+- **Be Specific**: Use exact node types, properties, and configurations mentioned in the fix
+- **Be Realistic**: Create test scenarios that mirror actual n8n usage
+- **Be Clear**: Report results in a structured, easy-to-understand format
+- **Be Efficient**: Focus testing on the changed functionality first
+
+## Example Test Execution
+
+If testing a validation fix for HTTP Request nodes:
+1. Call `tools_documentation` to get a list of available tools and get documentation on `search_nodes` tool.
+2. Search for HTTP Request node using `search_nodes`
+3. Get node configuration with `get_node_info` or `get_node_essentials`
+4. Create test configurations that previously failed
+5. Validate using `validate_node_config` with different profiles
+6. Test in a complete workflow using `n8n_validate_workflow`
+6. Report whether validation now works correctly
+
+## Important Constraints
+
+- You can only test using the MCP tools available in the server
+- You cannot modify code or files - only test existing functionality
+- You must work with the current state of the MCP server (already reloaded)
+- Focus on functional testing, not unit testing
+- Report issues objectively without attempting to fix them
+
+## Response Format
+
+Structure your test results as:
+
+```
+### Test Report: [Feature/Fix Name]
+
+**Test Objective**: [What was being tested]
+
+**Test Scenarios**:
+1. [Scenario 1]: ✅/❌ [Result]
+2. [Scenario 2]: ✅/❌ [Result]
+
+**Findings**:
+- [Key finding 1]
+- [Key finding 2]
+
+**Conclusion**: [Overall assessment - works as expected / issues found]
+
+**Details**: [Any error messages, unexpected behaviors, or additional context]
+```
+
+Remember: Your role is to validate that the n8n-mcp server works correctly in practice, providing confidence that fixes and new features function as intended before deployment.

+description: Use this agent when you need to create comprehensive test suites, improve test coverage, or set up test automation infrastructure. This includes writing unit tests with mocks, integration tests with test containers, E2E tests with Playwright/Cypress, configuring CI/CD pipelines for testing, or establishing test data management strategies.

+---
+
+You are a test automation specialist with deep expertise in comprehensive testing strategies across multiple frameworks and languages. Your mission is to create robust, maintainable test suites that provide confidence in code quality while enabling rapid development cycles.
+
+## Core Responsibilities
+
+You will design and implement test suites following the test pyramid principle:
+- **Unit Tests (70%)**: Fast, isolated tests with extensive mocking and stubbing
+- **Integration Tests (20%)**: Tests verifying component interactions, using test containers when needed
+- **E2E Tests (10%)**: Critical user journey tests using Playwright, Cypress, or similar tools
+
+## Testing Philosophy
+
+1. **Test Behavior, Not Implementation**: Focus on what the code does, not how it does it. Tests should survive refactoring.
+2. **Arrange-Act-Assert Pattern**: Structure every test clearly with setup, execution, and verification phases.
+3. **Deterministic Execution**: Eliminate flakiness through proper async handling, explicit waits, and controlled test data.
+4. **Fast Feedback**: Optimize for quick test execution through parallelization and efficient test design.
+5. **Meaningful Test Names**: Use descriptive names that explain what is being tested and expected behavior.
+
+## Implementation Guidelines
+
+### Unit Testing
+- Create focused tests for individual functions/methods
+- Mock all external dependencies (databases, APIs, file systems)
+- Use factories or builders for test data creation
+- Include edge cases: null values, empty collections, boundary conditions
+- Aim for high code coverage but prioritize critical paths
+
+### Integration Testing
+- Test real interactions between components
+- Use test containers for databases and external services
+- Verify data persistence and retrieval
+- Test transaction boundaries and rollback scenarios
+- Include error handling and recovery tests
+
+### E2E Testing
+- Focus on critical user journeys only
+- Use page object pattern for maintainability
+- Implement proper wait strategies (no arbitrary sleeps)
+- Create reusable test utilities and helpers
+- Include accessibility checks where applicable
+
+### Test Data Management
+- Create factories or fixtures for consistent test data
+- Use builders for complex object creation
+- Implement data cleanup strategies
+- Separate test data from production data
+- Version control test data schemas
+
+### CI/CD Integration
+- Configure parallel test execution
+- Set up test result reporting and artifacts
+- Implement test retry strategies for network-dependent tests
+- Create test environment provisioning
+- Configure coverage thresholds and reporting
+
+## Output Requirements
+
+You will provide:
+1. **Complete test files** with all necessary imports and setup
+2. **Mock implementations** for external dependencies
+3. **Test data factories** or fixtures as separate modules
+4. **CI pipeline configuration** (GitHub Actions, GitLab CI, Jenkins, etc.)
+5. **Coverage configuration** files and scripts
+6. **E2E test scenarios** with page objects and utilities
+7. **Documentation** explaining test structure and running instructions
+
+## Framework Selection
+
+Choose appropriate frameworks based on the technology stack:
+- **JavaScript/TypeScript**: Jest, Vitest, Mocha + Chai, Playwright, Cypress
+- **Python**: pytest, unittest, pytest-mock, factory_boy
+- **Java**: JUnit 5, Mockito, TestContainers, REST Assured
+- **Go**: testing package, testify, gomock
+- **Ruby**: RSpec, Minitest, FactoryBot
+
+## Quality Checks
+
+Before finalizing any test suite, verify:
+- All tests pass consistently (run multiple times)
+- No hardcoded values or environment dependencies
+- Proper teardown and cleanup
+- Clear assertion messages for failures
+- Appropriate use of beforeEach/afterEach hooks
+- No test interdependencies
+- Reasonable execution time
+
+## Special Considerations
+
+- For async code, ensure proper promise handling and async/await usage
+- For UI tests, implement proper element waiting strategies
+- For API tests, validate both response structure and data
+- For performance-critical code, include benchmark tests
+- For security-sensitive code, include security-focused test cases
+
+When encountering existing tests, analyze them first to understand patterns and conventions before adding new ones. Always strive for consistency with the existing test architecture while improving where possible.

+This file defines the expected performance thresholds for n8n-mcp operations.
+
+## Critical Operations
+
+| Operation | Expected Time | Warning Threshold | Error Threshold |
+|-----------|---------------|-------------------|-----------------|
+| Node Loading (per package) | <100ms | 150ms | 200ms |
+| Database Query (simple) | <5ms | 10ms | 20ms |
+| Search (simple word) | <10ms | 20ms | 50ms |
+| Search (complex query) | <50ms | 100ms | 200ms |
+| Validation (simple config) | <1ms | 2ms | 5ms |
+| Validation (complex config) | <10ms | 20ms | 50ms |
+| MCP Tool Execution | <50ms | 100ms | 200ms |
+
+## Benchmark Categories
+
+### Node Loading Performance
+- **loadPackage**: Should handle large packages efficiently
+- **loadNodesFromPath**: Individual file loading should be fast
+- **parsePackageJson**: JSON parsing overhead should be minimal
+
+### Database Query Performance
+- **getNodeByType**: Direct lookups should be instant
+- **searchNodes**: Full-text search should scale well
+- **getAllNodes**: Pagination should prevent performance issues
+
+### Search Operations
+- **OR mode**: Should handle multiple terms efficiently
+- **AND mode**: More restrictive but still performant
+- **FUZZY mode**: Slower but acceptable for typo tolerance
+
+### Validation Performance
+- **minimal profile**: Fastest, only required fields
+- **ai-friendly profile**: Balanced performance
+- **strict profile**: Comprehensive but slower
+
+### MCP Tool Execution
+- Tools should respond quickly for interactive use
+- Complex operations may take longer but should remain responsive
+
+## Regression Detection
+
+Performance regressions are detected when:
+1. Any operation exceeds its warning threshold by 10%
+2. Multiple operations show degradation in the same category
+3. Average performance across all benchmarks degrades by 5%
+
+## Optimization Targets
+
+Future optimization efforts should focus on:
+1. **Search performance**: Implement FTS5 for better full-text search
+2. **Caching**: Add intelligent caching for frequently accessed nodes
+3. **Lazy loading**: Defer loading of large property schemas
+4. **Batch operations**: Optimize bulk inserts and updates

+
+## High-Level Architecture
+
+### Core Components
+
+1. **MCP Server** (`mcp/server.ts`)
+   - Implements Model Context Protocol for AI assistants
+   - Provides tools for searching, validating, and managing n8n nodes
+   - Supports both stdio (Claude Desktop) and HTTP modes
+
+2. **Database Layer** (`database/`)
+   - SQLite database storing all n8n node information
+   - Universal adapter pattern supporting both better-sqlite3 and sql.js
+   - Full-text search capabilities with FTS5
+
+3. **Node Processing Pipeline**
+   - **Loader** (`loaders/node-loader.ts`): Loads nodes from n8n packages
+   - **Parser** (`parsers/node-parser.ts`): Extracts node metadata and structure
+   - **Property Extractor** (`parsers/property-extractor.ts`): Deep property analysis
+   - **Docs Mapper** (`mappers/docs-mapper.ts`): Maps external documentation
+
+4. **Service Layer** (`services/`)
+   - **Property Filter**: Reduces node properties to AI-friendly essentials
+   - **Config Validator**: Multi-profile validation system
+   - **Expression Validator**: Validates n8n expression syntax
+   - **Workflow Validator**: Complete workflow structure validation
+
+5. **Template System** (`templates/`)
+   - Fetches and stores workflow templates from n8n.io
+   - Provides pre-built workflow examples
+   - Supports template search and validation
+
+### Key Design Patterns
+
+1. **Repository Pattern**: All database operations go through repository classes
+2. **Service Layer**: Business logic separated from data access
+3. **Validation Profiles**: Different validation strictness levels (minimal, runtime, ai-friendly, strict)
+4. **Diff-Based Updates**: Efficient workflow updates using operation diffs
+
+### MCP Tools Architecture
+
+The MCP server exposes tools in several categories:
+
+1. **Discovery Tools**: Finding and exploring nodes
+2. **Configuration Tools**: Getting node details and examples
+3. **Validation Tools**: Validating configurations before deployment
+4. **Workflow Tools**: Complete workflow validation
+5. **Management Tools**: Creating and updating workflows (requires API config)
+
+## Memories and Notes for Development
+
+### Development Workflow Reminders
+- When you make changes to MCP server, you need to ask the user to reload it before you test
+- When the user asks to review issues, you should use GH CLI to get the issue and all the comments
+- When the task can be divided into separated subtasks, you should spawn separate sub-agents to handle them in parallel
+- Use the best sub-agent for the task as per their descriptions
+
+### Testing Best Practices
+- Always run `npm run build` before testing changes
+- Use `npm run dev` to rebuild database after package updates
+- Check coverage with `npm run test:coverage`
+- Integration tests require a clean database state
+
+### Common Pitfalls
+- The MCP server needs to be reloaded in Claude Desktop after changes
+- HTTP mode requires proper CORS and auth token configuration
+- Database rebuilds can take 2-3 minutes due to n8n package size
+- Always validate workflows before deployment to n8n
+
+### Performance Considerations
+- Use `get_node_essentials()` instead of `get_node_info()` for faster responses
+- Batch validation operations when possible
+- The diff-based update system saves 80-90% tokens on workflow updates
+
+### Agent Interaction Guidelines
+- Sub-agents are not allowed to spawn further sub-agents
+- When you use sub-agents, do not allow them to commit and push. That should be done by you
+
+### Development Best Practices
+- Run typecheck and lint after every code change
+
+# important-instruction-reminders
+Do what has been asked; nothing more, nothing less.
+NEVER create files unless they're absolutely necessary for achieving your goal.
+ALWAYS prefer editing an existing file to creating a new one.
+NEVER proactively create documentation files (*.md) or README files. Only create documentation files if explicitly requested by the User.

 ## ⚠️ Known Issues
 
-### Claude Desktop Container Duplication
-When using n8n-MCP with Claude Desktop in Docker mode, Claude Desktop may start the container twice during initialization. This is a known Claude Desktop bug ([modelcontextprotocol/servers#812](https://github.com/modelcontextprotocol/servers/issues/812)).
+### Claude Desktop Container Management
 
-**Symptoms:**
-- Two identical containers running for the same MCP server
-- Container name conflicts if using `--name` parameter
-- Doubled resource usage
+#### Container Accumulation (Fixed in v2.7.20+)
+Previous versions had an issue where containers would not properly clean up when Claude Desktop sessions ended. This has been fixed in v2.7.20+ with proper signal handling.
 
-**Workarounds:**
-1. **Avoid using --name parameter** - Let Docker assign random names:
+**For best container lifecycle management:**
+1. **Use the --init flag** (recommended) - Docker's init system ensures proper signal handling:

+# Docker Usage Guide for n8n-mcp
+
+## Running in HTTP Mode
+
+The n8n-mcp Docker container can be run in HTTP mode using several methods:
+
+### Method 1: Using Environment Variables (Recommended)
+
+```bash
+docker run -d -p 3000:3000 \
+  --name n8n-mcp-server \
+  -e MCP_MODE=http \
+  -e AUTH_TOKEN=your-secure-token-here \
+  ghcr.io/czlonkowski/n8n-mcp:latest
+```
+
+### Method 2: Using docker-compose
+
+```bash
+# Create a .env file
+cat > .env << EOF
+MCP_MODE=http
+AUTH_TOKEN=your-secure-token-here
+PORT=3000
+EOF
+
+# Run with docker-compose
+docker-compose up -d
+```
+
+### Method 3: Using a Configuration File
+
+Create a `config.json` file:
+```json
+{
+  "MCP_MODE": "http",
+  "AUTH_TOKEN": "your-secure-token-here",
+  "PORT": "3000",
+  "LOG_LEVEL": "info"
+}
+```
+
+Run with the config file:
+```bash
+docker run -d -p 3000:3000 \
+  --name n8n-mcp-server \
+  -v $(pwd)/config.json:/app/config.json:ro \
+  ghcr.io/czlonkowski/n8n-mcp:latest
+```
+
+### Method 4: Using the n8n-mcp serve Command
+
+```bash
+docker run -d -p 3000:3000 \
+  --name n8n-mcp-server \
+  -e AUTH_TOKEN=your-secure-token-here \
+  ghcr.io/czlonkowski/n8n-mcp:latest \
+  n8n-mcp serve
+```
+
+## Important Notes
+
+1. **AUTH_TOKEN is required** for HTTP mode. Generate a secure token:
+   ```bash
+   openssl rand -base64 32
+   ```
+
+2. **Environment variables take precedence** over config file values
+
+3. **Default mode is stdio** if MCP_MODE is not specified
+
+4. **Health check endpoint** is available at `http://localhost:3000/health`
+
+## Troubleshooting
+
+### Container exits immediately
+- Check logs: `docker logs n8n-mcp-server`
+- Ensure AUTH_TOKEN is set for HTTP mode
+
+### "n8n-mcp: not found" error
+- This has been fixed in the latest version
+- Use the full command: `node /app/dist/mcp/index.js` as a workaround
+
+### Config file not working
+- Ensure the file is valid JSON
+- Mount as read-only: `-v $(pwd)/config.json:/app/config.json:ro`
+- Check that the config parser is present: `docker exec n8n-mcp-server ls -la /app/docker/`

+# Automated Release Process
+
+This document describes the automated release system for n8n-mcp, which handles version detection, changelog parsing, and multi-artifact publishing.
+
+## Overview
+
+The automated release system is triggered when the version in `package.json` is updated and pushed to the main branch. It handles:
+
+- 🏷️ **GitHub Releases**: Creates releases with changelog content
+- 📦 **NPM Publishing**: Publishes optimized runtime package
+- 🐳 **Docker Images**: Builds and pushes multi-platform images
+- 📚 **Documentation**: Updates version badges automatically
+
+## Quick Start
+
+### For Maintainers
+
+Use the prepared release script for a guided experience:
+
+```bash
+npm run prepare:release
+```
+
+This script will:
+1. Prompt for the new version
+2. Update `package.json` and `package.runtime.json`
+3. Update the changelog
+4. Run tests and build
+5. Create a git commit
+6. Optionally push to trigger the release
+
+### Manual Process
+
+1. **Update the version**:
+   ```bash
+   # Edit package.json version field
+   vim package.json
+   
+   # Sync to runtime package
+   npm run sync:runtime-version
+   ```
+
+2. **Update the changelog**:
+   ```bash
+   # Edit docs/CHANGELOG.md
+   vim docs/CHANGELOG.md
+   ```
+
+3. **Test and commit**:
+   ```bash
+   # Ensure everything works
+   npm test
+   npm run build
+   npm run rebuild
+   
+   # Commit changes
+   git add package.json package.runtime.json docs/CHANGELOG.md
+   git commit -m "chore: release vX.Y.Z"
+   git push
+   ```
+
+## Workflow Details
+
+### Version Detection
+
+The workflow monitors pushes to the main branch and detects when `package.json` version changes:
+
+```yaml
+paths:
+  - 'package.json'
+  - 'package.runtime.json'
+```
+
+### Changelog Parsing
+
+Automatically extracts release notes from `docs/CHANGELOG.md` using the version header format:
+
+```markdown
+## [2.10.0] - 2025-08-02
+
+### Added
+- New feature descriptions
+
+### Changed
+- Changed feature descriptions
+
+### Fixed
+- Bug fix descriptions
+```
+
+### Release Artifacts
+
+#### GitHub Release
+- Created with extracted changelog content
+- Tagged with `vX.Y.Z` format
+- Includes installation instructions
+- Links to documentation
+
+#### NPM Package
+- Published as `n8n-mcp` on npmjs.com
+- Uses runtime-only dependencies (8 packages vs 50+ dev deps)
+- Optimized for `npx` usage
+- ~50MB vs 1GB+ with dev dependencies
+
+#### Docker Images
+- **Standard**: `ghcr.io/czlonkowski/n8n-mcp:vX.Y.Z`
+- **Railway**: `ghcr.io/czlonkowski/n8n-mcp-railway:vX.Y.Z`
+- Multi-platform: linux/amd64, linux/arm64
+- Semantic version tags: `vX.Y.Z`, `vX.Y`, `vX`, `latest`
+
+## Configuration
+
+### Required Secrets
+
+Set these in GitHub repository settings → Secrets:
+
+| Secret | Description | Required |
+|--------|-------------|----------|
+| `NPM_TOKEN` | NPM authentication token for publishing | ✅ Yes |
+| `GITHUB_TOKEN` | Automatically provided by GitHub Actions | ✅ Auto |
+
+### NPM Token Setup
+
+1. Login to [npmjs.com](https://www.npmjs.com)
+2. Go to Account Settings → Access Tokens
+3. Create a new **Automation** token
+4. Add as `NPM_TOKEN` secret in GitHub
+
+## Testing
+
+### Test Release Automation
+
+Validate the release system without triggering a release:
+
+```bash
+npm run test:release-automation
+```
+
+This checks:
+- ✅ File existence and structure
+- ✅ Version detection logic
+- ✅ Changelog parsing
+- ✅ Build process
+- ✅ NPM package preparation
+- ✅ Docker configuration
+- ✅ Workflow syntax
+- ✅ Environment setup
+
+### Local Testing
+
+Test individual components:
+
+```bash
+# Test version detection
+node -e "console.log(require('./package.json').version)"
+
+# Test changelog parsing
+node scripts/test-release-automation.js
+
+# Test npm package preparation
+npm run prepare:publish
+
+# Test Docker build
+docker build -t test-image .
+```
+
+## Workflow Jobs
+
+### 1. Version Detection
+- Compares current vs previous version in git history
+- Determines if it's a prerelease (alpha, beta, rc, dev)
+- Outputs version information for other jobs
+
+### 2. Changelog Extraction
+- Parses `docs/CHANGELOG.md` for the current version
+- Extracts content between version headers
+- Provides formatted release notes
+
+### 3. GitHub Release Creation
+- Creates annotated git tag
+- Creates GitHub release with changelog content
+- Handles prerelease flag for alpha/beta versions
+
+### 4. Build and Test
+- Installs dependencies
+- Runs full test suite
+- Builds TypeScript
+- Rebuilds node database
+- Type checking
+
+### 5. NPM Publishing
+- Prepares optimized package structure
+- Uses `package.runtime.json` for dependencies
+- Publishes to npmjs.com registry
+- Automatic cleanup
+
+### 6. Docker Building
+- Multi-platform builds (amd64, arm64)
+- Two image variants (standard, railway)
+- Semantic versioning tags
+- GitHub Container Registry
+
+### 7. Documentation Updates
+- Updates version badges in README
+- Commits documentation changes
+- Automatic push back to repository
+
+## Monitoring
+
+### GitHub Actions
+Monitor releases at: https://github.com/czlonkowski/n8n-mcp/actions
+
+### Release Status
+- **GitHub Releases**: https://github.com/czlonkowski/n8n-mcp/releases
+- **NPM Package**: https://www.npmjs.com/package/n8n-mcp
+- **Docker Images**: https://github.com/czlonkowski/n8n-mcp/pkgs/container/n8n-mcp
+
+### Notifications
+
+The workflow provides comprehensive summaries:
+- ✅ Success notifications with links
+- ❌ Failure notifications with error details
+- 📊 Artifact information and installation commands
+
+## Troubleshooting
+
+### Common Issues
+
+#### NPM Publishing Fails
+```
+Error: 401 Unauthorized
+```
+**Solution**: Check NPM_TOKEN secret is valid and has publishing permissions.
+
+#### Docker Build Fails
+```
+Error: failed to solve: could not read from registry
+```
+**Solution**: Check GitHub Container Registry permissions and GITHUB_TOKEN.
+
+#### Changelog Parsing Fails
+```
+No changelog entries found for version X.Y.Z
+```
+**Solution**: Ensure changelog follows the correct format:
+```markdown
+## [X.Y.Z] - YYYY-MM-DD
+```
+
+#### Version Detection Fails
+```
+Version not incremented
+```
+**Solution**: Ensure new version is greater than the previous version.
+
+### Recovery Steps
+
+#### Failed NPM Publish
+1. Check if version was already published
+2. If not, manually publish:
+   ```bash
+   npm run prepare:publish
+   cd npm-publish-temp
+   npm publish
+   ```
+
+#### Failed Docker Build
+1. Build locally to test:
+   ```bash
+   docker build -t test-build .
+   ```
+2. Re-trigger workflow or push a fix
+
+#### Incomplete Release
+1. Delete the created tag if needed:
+   ```bash
+   git tag -d vX.Y.Z
+   git push --delete origin vX.Y.Z
+   ```
+2. Fix issues and push again
+
+## Security
+
+### Secrets Management
+- NPM_TOKEN has limited scope (publish only)
+- GITHUB_TOKEN has automatic scoping
+- No secrets are logged or exposed
+
+### Package Security
+- Runtime package excludes development dependencies
+- No build tools or test frameworks in published package
+- Minimal attack surface (~50MB vs 1GB+)
+
+### Docker Security
+- Multi-stage builds
+- Non-root user execution
+- Minimal base images
+- Security scanning enabled
+
+## Changelog Format
+
+The automated system expects changelog entries in [Keep a Changelog](https://keepachangelog.com/) format:
+
+```markdown
+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+## [Unreleased]

+```
+
+### Continuous Integration
+
+Benchmarks run automatically on:
+- Every push to `main` branch
+- Every pull request
+- Manual workflow dispatch
+
+Results are:
+- Tracked over time using GitHub Actions
+- Displayed in PR comments
+- Available at: https://czlonkowski.github.io/n8n-mcp/benchmarks/
+
+## Benchmark Suites
+
+### 1. Node Loading Performance

+- Individual node file loading (< 5ms target)
+- Package.json parsing (< 1ms target)
+
+### 2. Database Query Performance
+Measures database operation performance including queries, inserts, and updates.
+
+**Key Metrics:**
+- Node retrieval by type (< 5ms target)
+- Search operations (< 50ms target)
+- Bulk operations (< 100ms target)
+
+### 3. Search Operations
+Tests various search modes and their performance characteristics.
+
+**Key Metrics:**
+- Simple word search (< 10ms target)
+- Multi-word OR search (< 20ms target)
+- Fuzzy search (< 50ms target)
+
+### 4. Validation Performance

+
+## Performance Targets
+
+| Operation Category | Target | Warning | Critical |
+|-------------------|--------|---------|----------|
+| Node Loading | < 100ms | > 150ms | > 200ms |
+| Database Query | < 5ms | > 10ms | > 20ms |

+| Validation | < 10ms | > 20ms | > 50ms |
+| MCP Tools | < 50ms | > 100ms | > 200ms |
+
+## Optimization Guidelines
+
+### Current Optimizations
+
+1. **In-memory caching**: Frequently accessed nodes are cached
+2. **Indexed database**: Key fields are indexed for fast lookups
+3. **Lazy loading**: Large properties are loaded on demand
+4. **Batch operations**: Multiple operations are batched when possible
+
+### Future Optimizations
+
+1. **FTS5 Search**: Implement SQLite FTS5 for faster full-text search
+2. **Connection pooling**: Reuse database connections
+3. **Query optimization**: Analyze and optimize slow queries
+4. **Parallel loading**: Load multiple packages concurrently
+
+## Benchmark Implementation
+
+### Writing New Benchmarks
+
+```typescript
+import { bench, describe } from 'vitest';
+
+describe('My Performance Suite', () => {
+  bench('operation name', async () => {
+    // Code to benchmark
+  }, {
+    iterations: 100,
+    warmupIterations: 10,
+    warmupTime: 500,
+    time: 3000
+  });
+});
+```
+
+### Best Practices
+
+1. **Isolate operations**: Benchmark specific operations, not entire workflows
+2. **Use realistic data**: Load actual n8n nodes for accurate measurements
+3. **Include warmup**: Allow JIT compilation to stabilize
+4. **Consider memory**: Monitor memory usage for memory-intensive operations
+5. **Statistical significance**: Run enough iterations for reliable results
+
+## Interpreting Results
+
+### Key Metrics
+
+- **hz**: Operations per second (higher is better)
+- **mean**: Average time per operation (lower is better)
+- **p99**: 99th percentile (worst-case performance)
+- **rme**: Relative margin of error (lower is more reliable)
+
+### Performance Regression Detection
+
+A performance regression is flagged when:
+1. Operation time increases by >10% from baseline
+2. Multiple related operations show degradation
+3. P99 latency exceeds critical thresholds
+
+### Analyzing Trends
+
+1. **Gradual degradation**: Often indicates growing technical debt
+2. **Sudden spikes**: Usually from specific code changes
+3. **Seasonal patterns**: May indicate cache effectiveness
+4. **Outliers**: Check p99 vs mean for consistency
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Inconsistent results**: Increase warmup iterations
+2. **High variance**: Check for background processes
+3. **Memory issues**: Reduce iteration count
+4. **CI failures**: Verify runner resources
+
+### Performance Debugging
+
+1. Use `--reporter=verbose` for detailed output
+2. Profile with `node --inspect` for bottlenecks
+3. Check database query plans
+4. Monitor memory allocation patterns
+
+## Contributing
+
+When submitting performance improvements:
+
+1. Run benchmarks before and after changes
+2. Include benchmark results in PR description
+3. Explain optimization approach
+4. Consider trade-offs (memory vs speed)
+5. Add new benchmarks for new features

+
+## [2.7.19] - 2025-07-18
+
+### Fixed
+- **Enhanced node type format normalization** (Issue #74)
+  - Fixed issue where `n8n-nodes-langchain.chattrigger` (incorrect format) was not being normalized
+  - Added support for `n8n-nodes-langchain.*` → `nodes-langchain.*` normalization (without @n8n/ prefix)
+  - Implemented case-insensitive node name matching (e.g., `chattrigger` → `chatTrigger`)
+  - Added smart camelCase detection for common patterns (trigger, request, sheets, etc.)
+  - Fixed `get_node_documentation` tool to use same normalization logic as other tools
+  - All MCP tools now consistently handle various format variations:
+    - `nodes-langchain.chatTrigger` (correct format)
+    - `n8n-nodes-langchain.chatTrigger` (package format)
+    - `n8n-nodes-langchain.chattrigger` (package + wrong case)
+    - `nodes-langchain.chattrigger` (wrong case only)
+    - `@n8n/n8n-nodes-langchain.chatTrigger` (full npm format)
+  - Updated all 7 node lookup locations to use normalized types for alternatives generation
+  - Enhanced `getNodeTypeAlternatives()` to normalize all generated alternatives
+
+## [2.7.18] - 2025-07-18
+
+### Fixed
+- **Node type prefix normalization for AI agents** (Issue #71)
+  - AI agents can now use node types directly from n8n workflow exports without manual conversion
+  - Added automatic normalization: `n8n-nodes-base.httpRequest` → `nodes-base.httpRequest`
+  - Added automatic normalization: `@n8n/n8n-nodes-langchain.agent` → `nodes-langchain.agent`
+  - Fixed 9 MCP tools that were failing with full package names:
+    - `get_node_info`, `get_node_essentials`, `get_node_as_tool_info`
+    - `search_node_properties`, `validate_node_minimal`, `validate_node_config`
+    - `get_property_dependencies`, `search_nodes`, `get_node_documentation`
+  - Maintains backward compatibility - existing short prefixes continue to work
+  - Created centralized `normalizeNodeType` utility for consistent handling across all tools
+- **Health check endpoint** - Fixed incorrect `/health` endpoint usage
+  - Now correctly uses `/healthz` endpoint which is available on all n8n instances
+  - Improved error handling with proper fallback to workflow list endpoint
+  - Fixed axios import for healthz endpoint access
+- **n8n_list_workflows pagination clarity** (Issue #54)
+  - Changed misleading `total` field to `returned` to clarify it's the count of items in current page
+  - Added `hasMore` boolean flag for clear pagination indication
+  - Added `_note` field with guidance when more data is available ("More workflows available. Use cursor to get next page.")
+  - Applied same improvements to `n8n_list_executions` for consistency
+  - AI agents now correctly understand they need to use pagination instead of assuming limited total workflows
+
+### Added
+- **Node type utilities** in `src/utils/node-utils.ts`
+  - `normalizeNodeType()` - Converts full package names to database format
+  - `getNodeTypeAlternatives()` - Provides fallback options for edge cases
+  - `getWorkflowNodeType()` - Constructs proper n8n workflow format from database values
+- **workflowNodeType field** in all MCP tool responses that return node information
+  - AI agents now receive both `nodeType` (internal format) and `workflowNodeType` (n8n format)
+  - Example: `nodeType: "nodes-base.webhook"`, `workflowNodeType: "n8n-nodes-base.webhook"`
+  - Prevents confusion where AI agents would search nodes and use wrong format in workflows
+  - Added to: `search_nodes`, `get_node_info`, `get_node_essentials`, `get_node_as_tool_info`, `validate_node_operation`
+- **Version information in health check**
+  - `n8n_health_check` now returns MCP version and supported n8n version
+  - Added `mcpVersion`, `supportedN8nVersion`, and `versionNote` fields
+  - Includes instructions for AI agents to inform users about version compatibility
+  - Note: n8n API currently doesn't expose instance version, so manual verification is required
+
+### Performance
+- **n8n_list_workflows response size optimization**
+  - Tool now returns only minimal metadata (id, name, active, dates, tags, nodeCount) instead of full workflow structure
+  - Reduced response size by ~95% - from potentially thousands of tokens per workflow to ~10 tokens
+  - Eliminated token limit errors when listing workflows with many nodes
+  - Updated tool description to clarify it returns "minimal metadata only"
+  - Users should use `n8n_get_workflow` to fetch full workflow details when needed
+
+## [2.7.17] - 2025-07-17
+
+### Fixed
+- **Removed faulty auto-generated examples from MCP tools** (Issue #60)
+  - Removed examples from `get_node_essentials` responses that were misleading AI agents
+  - Removed examples from `validate_node_operation` when validation errors occur
+  - Examples were showing incorrect configurations (e.g., Slack showing "channel" property instead of required "select" property)
+  - Tools now focus on validation errors and fix suggestions instead of potentially incorrect examples
+  - Preserved helpful format hints in `get_node_for_task` (these show input formats like "#general" or URL examples, not node configurations)
+  - This change reduces confusion and helps AI agents build correct workflows on the first attempt
+
+### Changed
+- Updated tool documentation to reflect removal of auto-generated examples
+- `get_node_essentials` now points users to `validate_node_operation` for working configurations
+- Enhanced validation error messages to be more helpful without relying on examples
+

+
+### Security
+- **Host Header Injection Prevention**: Added hostname validation to prevent malicious proxy headers

+  - Rejects hostnames with paths, usernames, or special characters
+  - Falls back to safe defaults when invalid headers are detected
+- **URL Scheme Validation**: Restricted URL schemes to http/https only
+  - Blocks dangerous schemes like javascript:, file://, data:
+  - Validates all configured URLs (BASE_URL, PUBLIC_URL)

+- **HTTP Bridge**: Updated to use HOST/PORT environment variables for default URL construction
+- **Documentation**: Updated HTTP deployment guide with URL configuration section
+
+## [2.7.14] - 2025-07-15
+
+### Fixed
+- **Partial Update Tool**: Fixed validation/execution discrepancy that caused "settings must NOT have additional properties" error (Issue #45)
+  - Removed logic in `cleanWorkflowForUpdate` that was incorrectly adding default settings to workflows
+  - The function now only removes read-only fields without adding any new properties
+  - This fixes the issue where partial updates would pass validation but fail during execution
+  - Added comprehensive test coverage in `test-issue-45-fix.ts`
+
+## [2.7.13] - 2025-07-11

+
+## [2.7.11] - 2025-07-09
+
+### Fixed
+- **Issue #26**: Fixed critical issue where AI agents were placing error handling properties inside `parameters` instead of at node level
+  - Root cause: AI agents were confused by examples showing `parameters.path` updates and assumed all properties followed the same pattern
+  - Error handling properties (`onError`, `retryOnFail`, `maxTries`, `waitBetweenTries`, `alwaysOutputData`) must be placed at the NODE level

+# Claude Code Setup
+
+Connect n8n-MCP to Claude Code CLI for enhanced n8n workflow development from the command line.
+
+## Quick Setup via CLI
+
+### Basic configuration (documentation tools only):
+```bash
+claude mcp add n8n-mcp \
+  -e MCP_MODE=stdio \
+  -e LOG_LEVEL=error \
+  -e DISABLE_CONSOLE_OUTPUT=true \
+  -- npx n8n-mcp
+```
+
+![Adding n8n-MCP server in Claude Code](./img/cc_command.png)
+
+### Full configuration (with n8n management tools):
+```bash
+claude mcp add n8n-mcp \
+  -e MCP_MODE=stdio \
+  -e LOG_LEVEL=error \
+  -e DISABLE_CONSOLE_OUTPUT=true \
+  -e N8N_API_URL=https://your-n8n-instance.com \
+  -e N8N_API_KEY=your-api-key \
+  -- npx n8n-mcp
+```
+
+Make sure to replace `https://your-n8n-instance.com` with your actual n8n URL and `your-api-key` with your n8n API key.
+
+## Alternative Setup Methods
+
+### Option 1: Import from Claude Desktop
+
+If you already have n8n-MCP configured in Claude Desktop:
+```bash
+claude mcp add-from-claude-desktop
+```
+
+### Option 2: Project Configuration
+
+For team sharing, add to `.mcp.json` in your project root:
+```json
+{
+  "mcpServers": {
+    "n8n-mcp": {
+      "command": "npx",
+      "args": ["n8n-mcp"],
+      "env": {
+        "MCP_MODE": "stdio",
+        "LOG_LEVEL": "error",
+        "DISABLE_CONSOLE_OUTPUT": "true",
+        "N8N_API_URL": "https://your-n8n-instance.com",
+        "N8N_API_KEY": "your-api-key"
+      }
+    }
+  }
+}
+```
+
+Then use with scope flag:
+```bash
+claude mcp add n8n-mcp --scope project
+```
+
+## Managing Your MCP Server
+
+Check server status:
+```bash
+claude mcp list
+claude mcp get n8n-mcp
+```
+
+During a conversation, use the `/mcp` command to see server status and available tools.
+
+![n8n-MCP connected and showing 39 tools available](./img/cc_connected.png)
+
+Remove the server:
+```bash
+claude mcp remove n8n-mcp
+```
+
+## Project Instructions
+
+For optimal results, create a `CLAUDE.md` file in your project root with the instructions from the [main README's Claude Project Setup section](../README.md#-claude-project-setup).
+
+## Tips
+
+- If you're running n8n locally, use `http://localhost:5678` as the N8N_API_URL
+- The n8n API credentials are optional - without them, you'll have documentation and validation tools only
+- With API credentials, you'll get full workflow management capabilities
+- Use `--scope local` (default) to keep your API credentials private
+- Use `--scope project` to share configuration with your team (put credentials in environment variables)
+- Claude Code will automatically start the MCP server when you begin a conversation

+# Codecov Setup Guide
+
+This guide explains how to set up and configure Codecov for the n8n-MCP project.
+
+## Prerequisites
+
+1. A Codecov account (sign up at https://codecov.io)
+2. Repository admin access to add the CODECOV_TOKEN secret
+
+## Setup Steps
+
+### 1. Get Your Codecov Token
+
+1. Sign in to [Codecov](https://codecov.io)
+2. Add your repository: `czlonkowski/n8n-mcp`
+3. Copy the upload token from the repository settings
+
+### 2. Add Token to GitHub Secrets
+
+1. Go to your GitHub repository settings
+2. Navigate to `Settings` → `Secrets and variables` → `Actions`
+3. Click "New repository secret"
+4. Name: `CODECOV_TOKEN`
+5. Value: Paste your Codecov token
+6. Click "Add secret"
+
+### 3. Update the Badge Token
+
+Edit the README.md file and replace `YOUR_TOKEN` in the Codecov badge with your actual token:
+
+```markdown
+[![codecov](https://codecov.io/gh/czlonkowski/n8n-mcp/graph/badge.svg?token=YOUR_ACTUAL_TOKEN)](https://codecov.io/gh/czlonkowski/n8n-mcp)
+```
+
+Note: The token in the badge URL is a read-only token and safe to commit.
+
+## Configuration Details
+
+### codecov.yml
+
+The configuration file sets:
+- **Target coverage**: 80% for both project and patch
+- **Coverage precision**: 2 decimal places
+- **Comment behavior**: Comments on all PRs with coverage changes
+- **Ignored files**: Test files, scripts, node_modules, and build outputs
+
+### GitHub Actions
+
+The workflow:
+1. Runs tests with coverage using `npm run test:coverage`
+2. Generates LCOV format coverage report
+3. Uploads to Codecov using the official action
+4. Fails the build if upload fails
+
+### Vitest Configuration
+
+Coverage settings in `vitest.config.ts`:
+- **Provider**: V8 (fast and accurate)
+- **Reporters**: text, json, html, and lcov
+- **Thresholds**: 80% lines, 80% functions, 75% branches, 80% statements
+
+## Viewing Coverage
+
+### Local Coverage
+
+```bash
+# Generate coverage report
+npm run test:coverage
+
+# View HTML report
+open coverage/index.html
+```
+
+### Online Coverage
+
+1. Visit https://codecov.io/gh/czlonkowski/n8n-mcp
+2. View detailed reports, graphs, and file-by-file coverage
+3. Check PR comments for coverage changes
+
+## Troubleshooting
+
+### Coverage Not Uploading
+
+1. Verify CODECOV_TOKEN is set in GitHub secrets
+2. Check GitHub Actions logs for errors
+3. Ensure coverage/lcov.info is generated
+
+### Badge Not Showing
+
+1. Wait a few minutes after first upload
+2. Verify the token in the badge URL is correct
+3. Check if the repository is public/private settings match
+
+### Low Coverage Areas
+
+Current areas with lower coverage that could be improved:
+- HTTP server implementations
+- MCP index files
+- Some edge cases in validators
+
+## Best Practices
+
+1. **Write tests first**: Aim for TDD when adding features
+2. **Focus on critical paths**: Prioritize testing core functionality
+3. **Mock external dependencies**: Use MSW for HTTP, mock for databases
+4. **Keep coverage realistic**: 80% is good, 100% isn't always practical
+5. **Monitor trends**: Watch coverage over time, not just absolute numbers

+## Common Issues
+
+### Docker Configuration File Not Working (v2.8.2+)
+
+**Symptoms:**
+- Config file mounted but environment variables not set
+- Container starts but ignores configuration
+- Getting "permission denied" errors
+
+**Solutions:**
+
+1. **Ensure file is mounted correctly:**
+```bash
+# Correct - mount as read-only
+docker run -v $(pwd)/config.json:/app/config.json:ro ...
+
+# Check if file is accessible
+docker exec n8n-mcp cat /app/config.json
+```
+
+2. **Verify JSON syntax:**
+```bash
+# Validate JSON file
+cat config.json | jq .
+```
+
+3. **Check Docker logs for parsing errors:**
+```bash
+docker logs n8n-mcp | grep -i config
+```
+
+4. **Common issues:**
+- Invalid JSON syntax (use a JSON validator)
+- File permissions (should be readable)
+- Wrong mount path (must be `/app/config.json`)
+- Dangerous variables blocked (PATH, LD_PRELOAD, etc.)
+
+### Custom Database Path Not Working (v2.7.16+)
+
+**Symptoms:**
+- `NODE_DB_PATH` environment variable is set but ignored
+- Database always created at `/app/data/nodes.db`
+- Custom path setting has no effect
+
+**Root Cause:** Fixed in v2.7.16. Earlier versions had hardcoded paths in docker-entrypoint.sh.
+
+**Solutions:**
+
+1. **Update to v2.7.16 or later:**
+```bash
+docker pull ghcr.io/czlonkowski/n8n-mcp:latest
+```
+
+2. **Ensure path ends with .db:**
+```bash
+# Correct
+NODE_DB_PATH=/app/data/custom/my-nodes.db
+
+# Incorrect (will be rejected)
+NODE_DB_PATH=/app/data/custom/my-nodes
+```
+
+3. **Use path within mounted volume for persistence:**
+```yaml
+services:
+  n8n-mcp:
+    environment:
+      NODE_DB_PATH: /app/data/custom/nodes.db
+    volumes:
+      - n8n-mcp-data:/app/data  # Ensure parent directory is mounted
+```
+
+### 502 Bad Gateway Errors
+
+**Symptoms:**
+- `n8n_health_check` returns 502 error
+- All n8n management API calls fail
+- n8n web UI is accessible but API is not
+
+**Root Cause:** Network connectivity issues between n8n-mcp container and n8n instance.
+
+**Solutions:**
+
+#### 1. When n8n runs in Docker on same machine
+
+Use Docker's special hostnames instead of `localhost`:
+
+```json
+{
+  "mcpServers": {
+    "n8n-mcp": {
+      "command": "docker",
+      "args": [
+        "run", "-i", "--rm",
+        "-e", "N8N_API_URL=http://host.docker.internal:5678",
+        "-e", "N8N_API_KEY=your-api-key",
+        "ghcr.io/czlonkowski/n8n-mcp:latest"
+      ]
+    }
+  }
+}
+```
+
+**Alternative hostnames to try:**
+- `host.docker.internal` (Docker Desktop on macOS/Windows)
+- `172.17.0.1` (Default Docker bridge IP on Linux)
+- Your machine's actual IP address (e.g., `192.168.1.100`)
+
+#### 2. When both containers are in same Docker network
+
+```bash
+# Create a shared network
+docker network create n8n-network
+
+# Run n8n in the network
+docker run -d --name n8n --network n8n-network -p 5678:5678 n8nio/n8n
+
+# Configure n8n-mcp to use container name
+```
+
+```json
+{
+  "N8N_API_URL": "http://n8n:5678"
+}
+```
+
+#### 3. For Docker Compose setups
+
+```yaml
+# docker-compose.yml
+services:
+  n8n:
+    image: n8nio/n8n
+    container_name: n8n
+    networks:
+      - n8n-net
+    ports:
+      - "5678:5678"
+  
+  n8n-mcp:
+    image: ghcr.io/czlonkowski/n8n-mcp:latest
+    environment:
+      N8N_API_URL: http://n8n:5678
+      N8N_API_KEY: ${N8N_API_KEY}
+    networks:
+      - n8n-net
+
+networks:
+  n8n-net:
+    driver: bridge
+```
+
+### Container Cleanup Issues (Fixed in v2.7.20+)
+
+**Symptoms:**
+- Containers accumulate after Claude Desktop restarts
+- Containers show as "unhealthy" but don't clean up
+- `--rm` flag doesn't work as expected
+
+**Root Cause:** Fixed in v2.7.20 - containers weren't handling termination signals properly.
+
+**Solutions:**
+
+1. **Update to v2.7.20+ and use --init flag (Recommended):**
+```json
+{
+  "command": "docker",
+  "args": [
+    "run", "-i", "--rm", "--init",
+    "ghcr.io/czlonkowski/n8n-mcp:latest"
+  ]
+}
+```
+
+2. **Manual cleanup of old containers:**
+```bash
+# Remove all stopped n8n-mcp containers
+docker ps -a | grep n8n-mcp | grep Exited | awk '{print $1}' | xargs -r docker rm
+```
+
+3. **For versions before 2.7.20:**
+- Manually clean up containers periodically
+- Consider using HTTP mode instead
+
+### n8n API Connection Issues
+
+**Symptoms:**
+- API calls fail but n8n web UI works
+- Authentication errors
+- API endpoints return 404
+
+**Solutions:**
+
+1. **Verify n8n API is enabled:**
+   - Check n8n settings → REST API is enabled
+   - Ensure API key is valid and not expired
+
+2. **Test API directly:**
+```bash
+# From host machine
+curl -H "X-N8N-API-KEY: your-key" http://localhost:5678/api/v1/workflows
+
+# From inside Docker container
+docker run --rm curlimages/curl \
+  -H "X-N8N-API-KEY: your-key" \
+  http://host.docker.internal:5678/api/v1/workflows
+```
+
+3. **Check n8n environment variables:**
+```yaml
+environment:
+  - N8N_BASIC_AUTH_ACTIVE=true
+  - N8N_BASIC_AUTH_USER=user
+  - N8N_BASIC_AUTH_PASSWORD=password
+```
+
+## Docker Networking
+
+### Understanding Docker Network Modes
+
+| Scenario | Use This URL | Why |
+|----------|--------------|-----|
+| n8n on host, n8n-mcp in Docker | `http://host.docker.internal:5678` | Docker can't reach host's localhost |
+| Both in same Docker network | `http://container-name:5678` | Direct container-to-container |
+| n8n behind reverse proxy | `http://your-domain.com` | Use public URL |
+| Local development | `http://YOUR_LOCAL_IP:5678` | Use machine's IP address |
+
+### Finding Your Configuration
+
+```bash
+# Check if n8n is running in Docker
+docker ps | grep n8n
+
+# Find Docker network
+docker network ls
+
+# Get container details
+docker inspect n8n | grep NetworkMode
+
+# Find your local IP
+# macOS/Linux
+ifconfig | grep "inet " | grep -v 127.0.0.1
+
+# Windows
+ipconfig | findstr IPv4
+```
+
+## Quick Solutions
+
+### Solution 1: Use Host Network (Linux only)
+```json
+{
+  "command": "docker",
+  "args": [
+    "run", "-i", "--rm",
+    "--network", "host",
+    "-e", "N8N_API_URL=http://localhost:5678",
+    "ghcr.io/czlonkowski/n8n-mcp:latest"
+  ]
+}
+```
+
+### Solution 2: Use Your Machine's IP
+```json
+{
+  "N8N_API_URL": "http://192.168.1.100:5678"  // Replace with your IP
+}
+```
+
+### Solution 3: HTTP Mode Deployment
+Deploy n8n-mcp as HTTP server to avoid stdio/Docker issues:
+
+```bash
+# Start HTTP server
+docker run -d \
+  -p 3000:3000 \
+  -e MCP_MODE=http \
+  -e AUTH_TOKEN=your-token \
+  -e N8N_API_URL=http://host.docker.internal:5678 \
+  -e N8N_API_KEY=your-n8n-key \
+  ghcr.io/czlonkowski/n8n-mcp:latest
+
+# Configure Claude with mcp-remote
+```
+
+## Debugging Steps
+
+### 1. Enable Debug Logging
+```json
+{
+  "env": {
+    "LOG_LEVEL": "debug",
+    "DEBUG_MCP": "true"
+  }
+}
+```
+
+### 2. Test Connectivity
+```bash
+# Test from n8n-mcp container
+docker run --rm ghcr.io/czlonkowski/n8n-mcp:latest \
+  sh -c "apk add curl && curl -v http://host.docker.internal:5678/api/v1/workflows"
+```
+
+### 3. Check Docker Logs
+```bash
+# View n8n-mcp logs
+docker logs $(docker ps -q -f ancestor=ghcr.io/czlonkowski/n8n-mcp:latest)
+
+# View n8n logs
+docker logs n8n
+```
+
+### 4. Validate Environment
+```bash
+# Check what n8n-mcp sees
+docker run --rm ghcr.io/czlonkowski/n8n-mcp:latest \
+  sh -c "env | grep N8N"
+```
+
+### 5. Network Diagnostics
+```bash
+# Check Docker networks
+docker network inspect bridge
+
+# Test DNS resolution
+docker run --rm busybox nslookup host.docker.internal
+```
+
+## Platform-Specific Notes
+
+### Docker Desktop (macOS/Windows)
+- `host.docker.internal` works out of the box
+- Ensure Docker Desktop is running
+- Check Docker Desktop settings → Resources → Network
+
+### Linux
+- `host.docker.internal` requires Docker 20.10+
+- Alternative: Use `--add-host=host.docker.internal:host-gateway`
+- Or use the Docker bridge IP: `172.17.0.1`
+
+### Windows with WSL2
+- Use `host.docker.internal` or WSL2 IP
+- Check firewall rules for port 5678
+- Ensure n8n binds to `0.0.0.0` not `127.0.0.1`
+
+## Still Having Issues?
+
+1. **Check n8n logs** for API-related errors
+2. **Verify firewall/security** isn't blocking connections
+3. **Try simpler setup** - Run n8n-mcp on host instead of Docker
+4. **Report issue** with debug logs at [GitHub Issues](https://github.com/czlonkowski/n8n-mcp/issues)
+
+## Useful Commands
+
+```bash
+# Remove all n8n-mcp containers
+docker rm -f $(docker ps -aq -f ancestor=ghcr.io/czlonkowski/n8n-mcp:latest)
+
+# Test n8n API with curl

+**Key Points:**
+- Claude Desktop **only supports stdio** communication
+- `mcp-remote` acts as a bridge, converting stdio ↔ HTTP
+- n8n-MCP server connects to **one n8n instance** (configured server-side)
+- All clients share the same n8n instance (single-tenant design)

 ## 🌐 Reverse Proxy Configuration
 
+### URL Configuration (v2.7.14+)
+
+n8n-MCP intelligently detects your public URL:
+
+#### Priority Order:
+1. **Explicit Configuration** (highest priority):
+   ```bash
+   BASE_URL=https://n8n-mcp.example.com  # Full public URL
+   # or
+   PUBLIC_URL=https://api.company.com:8443/mcp
+   ```
+
+2. **Auto-Detection** (when TRUST_PROXY is enabled):
+   ```bash
+   TRUST_PROXY=1  # Required for proxy header detection
+   # Server reads X-Forwarded-Proto and X-Forwarded-Host
+   ```
+
+3. **Fallback** (local binding):
+   ```bash
+   # No configuration needed
+   # Shows: http://localhost:3000 (or configured HOST:PORT)
+   ```
+
+#### What You'll See in Logs:
+```

 ## 🔒 Security Best Practices
 
 ### 1. Token Management
 
+**DO:**
+- ✅ Use tokens with 32+ characters
+- ✅ Store tokens in secure files or secrets management
+- ✅ Rotate tokens regularly (monthly minimum)
+- ✅ Use different tokens for each environment
+- ✅ Monitor logs for authentication failures
+
+**DON'T:**
+- ❌ Use default or example tokens
+- ❌ Commit tokens to version control
+- ❌ Share tokens between environments
+- ❌ Log tokens in plain text
+
 ```bash
-# Generate strong tokens
+# Generate strong token
 openssl rand -base64 32
 
-# Rotate tokens regularly
-AUTH_TOKEN_NEW=$(openssl rand -base64 32)
-docker exec n8n-mcp env AUTH_TOKEN=$AUTH_TOKEN_NEW
+# Secure storage options:
+# 1. Docker secrets (recommended)
+echo $(openssl rand -base64 32) | docker secret create auth_token -

-## 🚀 Scaling & Performance
+### Cloud Platform Deployments
 
-### Performance Metrics
-
-- Average response time: **~12ms**
-- Memory usage: **~50-100MB**
-- Concurrent connections: **100+**
-- Database queries: **<5ms** with FTS5
-
-### Horizontal Scaling
-
-The server is stateless - scale easily:
-
-```yaml
-# Docker Swarm example
-deploy:
-  replicas: 3
-  update_config:
-    parallelism: 1
-    delay: 10s
-  restart_policy:
-    condition: on-failure
-```
-
-### Optimization Tips
-
-1. **Use Docker** for consistent performance
-2. **Enable HTTP/2** in your reverse proxy
-3. **Set up CDN** for static assets
-4. **Monitor memory** usage over time
-
-## 👥 Multi-User Service Considerations
-
-While n8n-MCP is designed for single-user deployments, you can build a multi-user service:
-
-1. **Use this as a core engine** with your own auth layer
-2. **Deploy multiple instances** with different tokens
-3. **Add user management** in your proxy layer
-4. **Implement rate limiting** per user
-
-See [Architecture Guide](./ARCHITECTURE.md) for building multi-user services.

+
+## Overview
+
+n8n-MCP is a Model Context Protocol server that provides AI assistants with comprehensive access to n8n node documentation and management capabilities. When connected to n8n via the MCP Client Tool node, it enables:
+- AI-powered workflow creation and validation
+- Access to documentation for 500+ n8n nodes
+- Workflow management through the n8n API
+- Real-time configuration validation
+
+## Local Testing
+
+### Quick Test Script
+
+Test n8n-MCP locally with the provided test script:
+
+```bash
+# Clone the repository
+git clone https://github.com/czlonkowski/n8n-mcp.git
+cd n8n-mcp
+
+# Build the project
+npm install
+npm run build
+
+# Run the integration test script
+./scripts/test-n8n-integration.sh
+```
+
+This script will:
+1. Start a real n8n instance in Docker
+2. Start n8n-MCP server configured for n8n
+3. Guide you through API key setup for workflow management
+4. Test the complete integration between n8n and n8n-MCP
+
+### Manual Local Setup
+
+For development or custom testing:
+
+1. **Prerequisites**:
+   - n8n instance running (local or remote)
+   - n8n API key (from n8n Settings → API)
+
+2. **Start n8n-MCP**:
+```bash
+# Set environment variables
+export N8N_MODE=true
+export MCP_MODE=http                       # Required for HTTP mode
+export N8N_API_URL=http://localhost:5678  # Your n8n instance URL
+export N8N_API_KEY=your-api-key-here       # Your n8n API key
+export MCP_AUTH_TOKEN=test-token-minimum-32-chars-long
+export AUTH_TOKEN=test-token-minimum-32-chars-long  # Same value as MCP_AUTH_TOKEN
+export PORT=3001
+
+# Start the server
+npm start
+```
+
+3. **Verify it's running**:
+```bash
+# Check health
+curl http://localhost:3001/health
+
+# Check MCP protocol endpoint (this is the endpoint n8n connects to)
+curl http://localhost:3001/mcp
+# Should return: {"protocolVersion":"2024-11-05"} for n8n compatibility
+```
+
+## Environment Variables Reference
+
+| Variable | Required | Description | Example Value |
+|----------|----------|-------------|---------------|
+| `N8N_MODE` | Yes | Enables n8n integration mode | `true` |
+| `MCP_MODE` | Yes | Enables HTTP mode for n8n MCP Client | `http` |
+| `N8N_API_URL` | Yes* | URL of your n8n instance | `http://localhost:5678` |
+| `N8N_API_KEY` | Yes* | n8n API key for workflow management | `n8n_api_xxx...` |
+| `MCP_AUTH_TOKEN` | Yes | Authentication token for MCP requests (min 32 chars) | `secure-random-32-char-token` |
+| `AUTH_TOKEN` | Yes | **MUST match MCP_AUTH_TOKEN exactly** | `secure-random-32-char-token` |
+| `PORT` | No | Port for the HTTP server | `3000` (default) |
+| `LOG_LEVEL` | No | Logging verbosity | `info`, `debug`, `error` |
+
+*Required only for workflow management features. Documentation tools work without these.
+
+## Docker Build Changes (v2.9.2+)
+
+Starting with version 2.9.2, we use a single optimized Dockerfile for all deployments:
+- The previous `Dockerfile.n8n` has been removed as redundant
+- N8N_MODE functionality is enabled via the `N8N_MODE=true` environment variable
+- This reduces image size by 500MB+ and improves build times from 8+ minutes to 1-2 minutes
+- All examples now use the standard `Dockerfile`
+
+## Production Deployment
+
+> **⚠️ Critical**: Docker caches images locally. Always run `docker pull ghcr.io/czlonkowski/n8n-mcp:latest` before deploying to ensure you have the latest version. This simple step prevents most deployment issues.
+
+### Same Server as n8n
+
+If you're running n8n-MCP on the same server as your n8n instance:
+
+### Using Pre-built Image (Recommended)
+
+The pre-built images are automatically updated with each release and are the easiest way to get started.
+
+**IMPORTANT**: Always pull the latest image to avoid using cached versions:
+
+```bash
+# ALWAYS pull the latest image first
+docker pull ghcr.io/czlonkowski/n8n-mcp:latest
+
+# Generate a secure token (save this!)
+AUTH_TOKEN=$(openssl rand -hex 32)
+echo "Your AUTH_TOKEN: $AUTH_TOKEN"
+
+# Create a Docker network if n8n uses one
+docker network create n8n-net
+
+# Run n8n-MCP container
+docker run -d \
+  --name n8n-mcp \
+  --network n8n-net \
+  -p 3000:3000 \
+  -e N8N_MODE=true \
+  -e MCP_MODE=http \
+  -e N8N_API_URL=http://n8n:5678 \
+  -e N8N_API_KEY=your-n8n-api-key \
+  -e MCP_AUTH_TOKEN=$AUTH_TOKEN \
+  -e AUTH_TOKEN=$AUTH_TOKEN \
+  -e LOG_LEVEL=info \
+  --restart unless-stopped \
+  ghcr.io/czlonkowski/n8n-mcp:latest
+```
+
+### Building from Source (Advanced Users)
+
+Only build from source if you need custom modifications or are contributing to development:
+
+```bash
+# Clone and build
+git clone https://github.com/czlonkowski/n8n-mcp.git
+cd n8n-mcp
+
+# Build Docker image
+docker build -t n8n-mcp:latest .
+
+# Run using your local image
+docker run -d \
+  --name n8n-mcp \
+  -p 3000:3000 \
+  -e N8N_MODE=true \
+  -e MCP_MODE=http \
+  -e MCP_AUTH_TOKEN=$(openssl rand -hex 32) \
+  -e AUTH_TOKEN=$(openssl rand -hex 32) \
+  # ... other settings
+  n8n-mcp:latest
+```
+
+### Using systemd (for native installation)
+
+```bash
+# Create service file
+sudo cat > /etc/systemd/system/n8n-mcp.service << EOF
+[Unit]
+Description=n8n-MCP Server
+After=network.target
+
+[Service]
+Type=simple
+User=nodejs
+WorkingDirectory=/opt/n8n-mcp
+Environment="N8N_MODE=true"
+Environment="MCP_MODE=http"
+Environment="N8N_API_URL=http://localhost:5678"
+Environment="N8N_API_KEY=your-n8n-api-key"
+Environment="MCP_AUTH_TOKEN=your-secure-token-32-chars-min"
+Environment="AUTH_TOKEN=your-secure-token-32-chars-min"
+Environment="PORT=3000"
+ExecStart=/usr/bin/node /opt/n8n-mcp/dist/mcp/index.js
+Restart=on-failure
+
+[Install]
+WantedBy=multi-user.target
+EOF
+
+# Enable and start
+sudo systemctl enable n8n-mcp
+sudo systemctl start n8n-mcp
+```
+
+### Different Server (Cloud Deployment)
+
+Deploy n8n-MCP on a separate server from your n8n instance:
+
+#### Quick Docker Deployment (Recommended)
+
+**Always pull the latest image to ensure you have the current version:**
+
+```bash
+# On your cloud server (Hetzner, AWS, DigitalOcean, etc.)
+# ALWAYS pull the latest image first
+docker pull ghcr.io/czlonkowski/n8n-mcp:latest
+
+# Generate auth tokens
+AUTH_TOKEN=$(openssl rand -hex 32)
+echo "Save this AUTH_TOKEN: $AUTH_TOKEN"
+
+# Run the container
+docker run -d \
+  --name n8n-mcp \
+  -p 3000:3000 \
+  -e N8N_MODE=true \
+  -e MCP_MODE=http \
+  -e N8N_API_URL=https://your-n8n-instance.com \
+  -e N8N_API_KEY=your-n8n-api-key \
+  -e MCP_AUTH_TOKEN=$AUTH_TOKEN \
+  -e AUTH_TOKEN=$AUTH_TOKEN \
+  -e LOG_LEVEL=info \
+  --restart unless-stopped \
+  ghcr.io/czlonkowski/n8n-mcp:latest
+```
+
+#### Building from Source (Advanced)
+
+Only needed if you're modifying the code:
+
+```bash
+# Clone and build
+git clone https://github.com/czlonkowski/n8n-mcp.git
+cd n8n-mcp
+docker build -t n8n-mcp:latest .
+
+# Run using local image
+docker run -d \
+  --name n8n-mcp \
+  -p 3000:3000 \
+  # ... same environment variables as above
+  n8n-mcp:latest
+```
+
+#### Full Production Setup (Hetzner/AWS/DigitalOcean)
+
+1. **Server Requirements**:
+   - **Minimal**: 1 vCPU, 1GB RAM (CX11 on Hetzner)
+   - **Recommended**: 2 vCPU, 2GB RAM
+   - **OS**: Ubuntu 22.04 LTS
+
+2. **Initial Setup**:
+```bash
+# SSH into your server
+ssh root@your-server-ip
+
+# Update and install Docker
+apt update && apt upgrade -y
+curl -fsSL https://get.docker.com | sh
+```
+
+3. **Deploy n8n-MCP with SSL** (using Caddy for automatic HTTPS):
+
+**Using Docker Compose (Recommended)**
+```bash
+# Create docker-compose.yml
+cat > docker-compose.yml << 'EOF'
+version: '3.8'
+
+services:
+  n8n-mcp:
+    image: ghcr.io/czlonkowski/n8n-mcp:latest
+    pull_policy: always  # Always pull latest image
+    container_name: n8n-mcp
+    restart: unless-stopped
+    environment:
+      - N8N_MODE=true
+      - MCP_MODE=http
+      - N8N_API_URL=${N8N_API_URL}
+      - N8N_API_KEY=${N8N_API_KEY}
+      - MCP_AUTH_TOKEN=${MCP_AUTH_TOKEN}
+      - AUTH_TOKEN=${AUTH_TOKEN}
+      - PORT=3000
+      - LOG_LEVEL=info
+    networks:
+      - web
+
+  caddy:
+    image: caddy:2-alpine
+    container_name: caddy
+    restart: unless-stopped
+    ports:

+      - web
+
+networks:
+  web:
+    driver: bridge
+
+volumes:
+  caddy_data:
+  caddy_config:
+EOF
+```
+
+**Note**: The `pull_policy: always` ensures you always get the latest version.
+
+**Building from Source (if needed)**
+```bash
+# Only if you need custom modifications
+git clone https://github.com/czlonkowski/n8n-mcp.git
+cd n8n-mcp
+docker build -t n8n-mcp:local .
+
+# Then update docker-compose.yml to use:
+# image: n8n-mcp:local
+    container_name: n8n-mcp
+    restart: unless-stopped
+    environment:
+      - N8N_MODE=true
+      - MCP_MODE=http
+      - N8N_API_URL=${N8N_API_URL}
+      - N8N_API_KEY=${N8N_API_KEY}
+      - MCP_AUTH_TOKEN=${MCP_AUTH_TOKEN}
+      - AUTH_TOKEN=${AUTH_TOKEN}
+      - PORT=3000
+      - LOG_LEVEL=info
+    networks:
+      - web
+
+  caddy:
+    image: caddy:2-alpine
+    container_name: caddy
+    restart: unless-stopped
+    ports:
+      - "80:80"
+      - "443:443"
+    volumes:
+      - ./Caddyfile:/etc/caddy/Caddyfile
+      - caddy_data:/data
+      - caddy_config:/config
+    networks:
+      - web
+
+networks:

+  caddy_config:
+EOF
+```
+
+**Complete the Setup**
+```bash
+# Create Caddyfile
+cat > Caddyfile << 'EOF'
+mcp.yourdomain.com {
+    reverse_proxy n8n-mcp:3000
+}
+EOF
+
+# Create .env file
+AUTH_TOKEN=$(openssl rand -hex 32)
+cat > .env << EOF
+N8N_API_URL=https://your-n8n-instance.com
+N8N_API_KEY=your-n8n-api-key-here
+MCP_AUTH_TOKEN=$AUTH_TOKEN
+AUTH_TOKEN=$AUTH_TOKEN
+EOF
+
+# Save the AUTH_TOKEN!
+echo "Your AUTH_TOKEN is: $AUTH_TOKEN"
+echo "Save this token - you'll need it in n8n MCP Client Tool configuration"
+
+# Start services
+docker compose up -d
+```
+
+#### Cloud Provider Tips
+
+**AWS EC2**:
+- Security Group: Open port 3000 (or 443 with HTTPS)
+- Instance Type: t3.micro is sufficient
+- Use Elastic IP for stable addressing
+
+**DigitalOcean**:
+- Droplet: Basic ($6/month) is enough
+- Enable backups for production use
+
+**Google Cloud**:
+- Machine Type: e2-micro (free tier eligible)
+- Use Cloud Load Balancer for SSL
+
+## Connecting n8n to n8n-MCP
+
+### Configure n8n MCP Client Tool
+
+1. **In your n8n workflow**, add the **MCP Client Tool** node
+
+2. **Configure the connection**:
+   ```
+   Server URL (MUST include /mcp endpoint): 
+   - Same server: http://localhost:3000/mcp
+   - Docker network: http://n8n-mcp:3000/mcp
+   - Different server: https://mcp.yourdomain.com/mcp
+   
+   Auth Token: [Your MCP_AUTH_TOKEN/AUTH_TOKEN value]
+   
+   Transport: HTTP Streamable (SSE)
+   ```
+   
+   ⚠️ **Critical**: The Server URL must include the `/mcp` endpoint path. Without this, the connection will fail.
+
+3. **Test the connection** by selecting a simple tool like `list_nodes`
+
+### Available Tools
+
+Once connected, you can use these MCP tools in n8n:
+
+**Documentation Tools** (No API key required):
+- `list_nodes` - List all n8n nodes with filtering
+- `search_nodes` - Search nodes by keyword
+- `get_node_info` - Get detailed node information
+- `get_node_essentials` - Get only essential properties
+- `validate_workflow` - Validate workflow configurations
+- `get_node_documentation` - Get human-readable docs
+
+**Management Tools** (Requires n8n API key):
+- `n8n_create_workflow` - Create new workflows
+- `n8n_update_workflow` - Update existing workflows
+- `n8n_get_workflow` - Retrieve workflow details
+- `n8n_list_workflows` - List all workflows
+- `n8n_trigger_webhook_workflow` - Trigger webhook workflows
+
+### Using with AI Agents
+
+Connect n8n-MCP to AI Agent nodes for intelligent automation:
+
+1. **Add an AI Agent node** (e.g., OpenAI, Anthropic)
+2. **Connect MCP Client Tool** to the Agent's tool input
+3. **Configure prompts** for workflow creation:
+
+```
+You are an n8n workflow expert. Use the MCP tools to:
+1. Search for appropriate nodes using search_nodes
+2. Get configuration details with get_node_essentials
+3. Validate configurations with validate_workflow
+4. Create the workflow if all validations pass
+```
+
+## Security & Best Practices
+
+### Authentication
+- **MCP_AUTH_TOKEN**: Always use a strong, random token (32+ characters)
+- **N8N_API_KEY**: Only required for workflow management features
+- Store tokens in environment variables or secure vaults
+
+### Network Security
+- **Use HTTPS** in production (Caddy/Nginx/Traefik)
+- **Firewall**: Only expose necessary ports (3000 or 443)
+- **IP Whitelisting**: Consider restricting access to known n8n instances
+
+### Docker Security
+- **Always pull latest images**: Docker caches images locally, so run `docker pull` before deployment
+- Run containers with `--read-only` flag if possible
+- Use specific image versions instead of `:latest` in production
+- Regular updates: `docker pull ghcr.io/czlonkowski/n8n-mcp:latest`
+
+## Troubleshooting
+
+### Docker Image Issues
+
+**Using Outdated Cached Images**
+- **Symptom**: Missing features, old bugs reappearing, features not working as documented
+- **Cause**: Docker uses locally cached images instead of pulling the latest version
+- **Solution**: Always run `docker pull ghcr.io/czlonkowski/n8n-mcp:latest` before deployment
+- **Verification**: Check image age with `docker images | grep n8n-mcp`
+
+### Common Configuration Issues
+
+**Missing `MCP_MODE=http` Environment Variable**
+- **Symptom**: n8n MCP Client Tool cannot connect, server doesn't respond on `/mcp` endpoint
+- **Solution**: Add `MCP_MODE=http` to your environment variables
+- **Why**: Without this, the server runs in stdio mode which is incompatible with n8n
+
+**Server URL Missing `/mcp` Endpoint**
+- **Symptom**: "Connection refused" or "Invalid response" in n8n MCP Client Tool
+- **Solution**: Ensure your Server URL includes `/mcp` (e.g., `http://localhost:3000/mcp`)
+- **Why**: n8n connects to the `/mcp` endpoint specifically, not the root URL
+
+**Mismatched Auth Tokens**
+- **Symptom**: "Authentication failed" or "Invalid auth token"
+- **Solution**: Ensure both `MCP_AUTH_TOKEN` and `AUTH_TOKEN` have the same value
+- **Why**: Both variables must match for proper authentication
+
+### Connection Issues
+
+**"Connection refused" in n8n MCP Client Tool**
+1. **Check n8n-MCP is running**:
+   ```bash
+   # Docker
+   docker ps | grep n8n-mcp
+   docker logs n8n-mcp --tail 20
+   
+   # Systemd
+   systemctl status n8n-mcp
+   journalctl -u n8n-mcp --tail 20
+   ```
+
+2. **Verify endpoints are accessible**:
+   ```bash
+   # Health check (should return status info)
+   curl http://your-server:3000/health
+   
+   # MCP endpoint (should return protocol version)
+   curl http://your-server:3000/mcp
+   ```
+
+3. **Check firewall and networking**:
+   ```bash
+   # Test port accessibility from n8n server
+   telnet your-mcp-server 3000
+   
+   # Check firewall rules (Ubuntu/Debian)
+   sudo ufw status
+   
+   # Check if port is bound correctly
+   netstat -tlnp | grep :3000
+   ```
+
+**"Invalid auth token" or "Authentication failed"**
+1. **Verify token format**:
+   ```bash
+   # Check token length (should be 64 chars for hex-32)
+   echo $MCP_AUTH_TOKEN | wc -c
+   
+   # Verify both tokens match
+   echo "MCP_AUTH_TOKEN: $MCP_AUTH_TOKEN"
+   echo "AUTH_TOKEN: $AUTH_TOKEN"
+   ```
+
+2. **Common token issues**:
+   - Token too short (minimum 32 characters)
+   - Extra whitespace or newlines in token
+   - Different values for `MCP_AUTH_TOKEN` and `AUTH_TOKEN`
+   - Special characters not properly escaped in environment files
+
+**"Cannot connect to n8n API"**
+1. **Verify n8n configuration**:
+   ```bash
+   # Test n8n API accessibility
+   curl -H "X-N8N-API-KEY: your-api-key" \
+        https://your-n8n-instance.com/api/v1/workflows
+   ```
+
+2. **Common n8n API issues**:
+   - `N8N_API_URL` missing protocol (http:// or https://)
+   - n8n API key expired or invalid
+   - n8n instance not accessible from n8n-MCP server
+   - n8n API disabled in settings
+
+### Version Compatibility Issues
+
+**"Features Not Working as Expected"**
+- **Symptom**: Missing features, old bugs, or compatibility issues
+- **Solution**: Pull the latest image: `docker pull ghcr.io/czlonkowski/n8n-mcp:latest`
+- **Check**: Verify image date with `docker inspect ghcr.io/czlonkowski/n8n-mcp:latest | grep Created`
+
+**"Protocol version mismatch"**
+- n8n-MCP automatically uses version 2024-11-05 for n8n compatibility
+- Update to latest n8n-MCP version if issues persist
+- Verify `/mcp` endpoint returns correct version
+
+### Environment Variable Issues
+
+**Complete Environment Variable Checklist**:
+```bash
+# Required for all deployments
+export N8N_MODE=true                                    # Enables n8n integration
+export MCP_MODE=http                                   # Enables HTTP mode for n8n
+export MCP_AUTH_TOKEN=your-secure-32-char-token       # Auth token
+export AUTH_TOKEN=your-secure-32-char-token           # Same value as MCP_AUTH_TOKEN
+
+# Required for workflow management features
+export N8N_API_URL=https://your-n8n-instance.com      # Your n8n URL
+export N8N_API_KEY=your-n8n-api-key                   # Your n8n API key
+
+# Optional

+
+# Check Caddy logs
+docker logs caddy -f --tail 50
+```
+
+**Docker Network Issues**
+```bash
+# Check if containers can communicate
+docker network ls
+docker network inspect bridge
+
+# Test inter-container connectivity
+docker exec n8n curl http://n8n-mcp:3000/health
+```
+
+### Debugging Steps
+
+1. **Enable comprehensive logging**:
+```bash
+# For Docker
+docker run -d \
+  --name n8n-mcp \
+  -e DEBUG_MCP=true \
+  -e LOG_LEVEL=debug \
+  -e N8N_MODE=true \
+  -e MCP_MODE=http \
+  # ... other settings
+
+# For systemd, add to service file:
+Environment="DEBUG_MCP=true"
+Environment="LOG_LEVEL=debug"
+```
+
+2. **Test all endpoints systematically**:
+```bash
+# 1. Health check (basic server functionality)
+curl -v http://localhost:3000/health
+
+# 2. MCP protocol endpoint (what n8n connects to)
+curl -v http://localhost:3000/mcp
+
+# 3. Test authentication (if working, returns tools list)
+curl -X POST http://localhost:3000/mcp \
+  -H "Authorization: Bearer YOUR_AUTH_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"jsonrpc":"2.0","method":"tools/list","id":1}'
+
+# 4. Test a simple tool (documentation only, no n8n API needed)
+curl -X POST http://localhost:3000/mcp \
+  -H "Authorization: Bearer YOUR_AUTH_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"jsonrpc":"2.0","method":"tools/call","params":{"name":"get_database_statistics","arguments":{}},"id":2}'
+```
+
+3. **Common log patterns to look for**:
+```bash
+# Success patterns
+grep "Server started" /var/log/n8n-mcp.log
+grep "Protocol version" /var/log/n8n-mcp.log
+
+# Error patterns
+grep -i "error\|failed\|invalid" /var/log/n8n-mcp.log
+grep -i "auth\|token" /var/log/n8n-mcp.log
+grep -i "connection\|network" /var/log/n8n-mcp.log
+```
+
+### Getting Help
+
+If you're still experiencing issues:
+
+1. **Gather diagnostic information**:
+```bash
+# System info
+docker --version
+docker-compose --version
+uname -a
+
+# n8n-MCP version
+docker exec n8n-mcp node dist/index.js --version
+
+# Environment check
+docker exec n8n-mcp env | grep -E "(N8N|MCP|AUTH)" | sort
+
+# Container status
+docker ps | grep n8n-mcp
+docker stats n8n-mcp --no-stream
+```
+
+2. **Create a minimal test setup**:
+```bash
+# Test with minimal configuration
+docker run -d \
+  --name n8n-mcp-test \
+  -p 3001:3000 \
+  -e N8N_MODE=true \
+  -e MCP_MODE=http \
+  -e MCP_AUTH_TOKEN=test-token-minimum-32-chars-long \
+  -e AUTH_TOKEN=test-token-minimum-32-chars-long \
+  -e LOG_LEVEL=debug \
+  n8n-mcp:latest
+
+# Test basic functionality
+curl http://localhost:3001/health
+curl http://localhost:3001/mcp
+```
+
+3. **Report issues**: Include the diagnostic information when opening an issue on [GitHub](https://github.com/czlonkowski/n8n-mcp/issues)

+# Railway Deployment Guide for n8n-MCP
+
+Deploy n8n-MCP to Railway's cloud platform with zero configuration and connect it to Claude Desktop from anywhere.
+
+## 🚀 Quick Deploy
+
+Deploy n8n-MCP with one click:
+
+[![Deploy on Railway](https://railway.com/button.svg)](https://railway.com/deploy/VY6UOG?referralCode=n8n-mcp)
+
+## 📋 Overview
+
+Railway deployment provides:
+- ☁️ **Instant cloud hosting** - No server setup required
+- 🔒 **Secure by default** - HTTPS included, auth token warnings
+- 🌐 **Global access** - Connect from any Claude Desktop

+4. **Click "Deploy"** and wait ~2-3 minutes
+
+### 2. Configure Security
+
+**IMPORTANT**: The deployment includes a default AUTH_TOKEN for instant functionality, but you MUST change it:
+
+![Railway Dashboard - Variables Tab](./img/railway-variables.png)
+
+1. **Go to your Railway dashboard**
+2. **Click on your n8n-mcp service**
+3. **Navigate to "Variables" tab**
+4. **Find `AUTH_TOKEN`** 
+5. **Replace with secure token**:
+   ```bash
+   # Generate secure token locally:
+   openssl rand -base64 32
+   ```
+6. **Railway will automatically redeploy** with the new token
+
+> ⚠️ **Security Warning**: The server displays warnings every 5 minutes until you change the default token!
+
+### 3. Get Your Service URL
+
+![Railway Dashboard - Domain Settings](./img/railway-domain.png)
+
+1. In Railway dashboard, click on your service
+2. Go to **"Settings"** tab
+3. Under **"Domains"**, you'll see your URL:
+   ```
+   https://your-app-name.up.railway.app
+   ```
+4. Copy this URL for Claude Desktop configuration and add /mcp at the end
+
+### 4. Connect Claude Desktop
+
+Add to your Claude Desktop configuration:
+
+```json
+{
+  "mcpServers": {
+    "n8n-railway": {
+      "command": "npx",
+      "args": [
+        "-y",
+        "mcp-remote",
+        "https://your-app-name.up.railway.app/mcp",
+        "--header",
+        "Authorization: Bearer YOUR_SECURE_TOKEN_HERE"
+      ]
+    }
+  }
+}
+```
+
+**Configuration file locations:**
+- **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
+- **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
+- **Linux**: `~/.config/Claude/claude_desktop_config.json`
+
+**Restart Claude Desktop** after saving the configuration.
+
+## 🔧 Environment Variables
+
+### Default Variables (Pre-configured)
+
+These are automatically set by the Railway template:
+
+| Variable | Default Value | Description |
+|----------|--------------|-------------|
+| `AUTH_TOKEN` | `REPLACE_THIS...` | **⚠️ CHANGE IMMEDIATELY** |
+| `MCP_MODE` | `http` | Required for cloud deployment |
+| `USE_FIXED_HTTP` | `true` | Stable HTTP implementation |
+| `NODE_ENV` | `production` | Production optimizations |
+| `LOG_LEVEL` | `info` | Balanced logging |
+| `TRUST_PROXY` | `1` | Railway runs behind proxy |
+| `CORS_ORIGIN` | `*` | Allow any origin |
+| `HOST` | `0.0.0.0` | Listen on all interfaces |
+| `PORT` | (Railway provides) | Don't set manually |
+
+### Optional Variables
+
+| Variable | Default Value | Description |
+|----------|--------------|-------------|
+| `N8N_MODE` | `false` | Enable n8n integration mode for MCP Client Tool |
+| `N8N_API_URL` | - | URL of your n8n instance (for workflow management) |
+| `N8N_API_KEY` | - | API key from n8n Settings → API |
+
+### Optional: n8n Integration
+
+#### For n8n MCP Client Tool Integration
+
+To use n8n-MCP with n8n's MCP Client Tool node:
+
+1. **Go to Railway dashboard** → Your service → **Variables**
+2. **Add this variable**:
+   - `N8N_MODE`: Set to `true` to enable n8n integration mode
+3. **Save changes** - Railway will redeploy automatically
+
+#### For n8n API Integration (Workflow Management)
+
+To enable workflow management features:
+
+1. **Go to Railway dashboard** → Your service → **Variables**
+2. **Add these variables**:
+   - `N8N_API_URL`: Your n8n instance URL (e.g., `https://n8n.example.com`)
+   - `N8N_API_KEY`: API key from n8n Settings → API
+3. **Save changes** - Railway will redeploy automatically
+
+## 🏗️ Architecture Details
+
+### How It Works
+
+```
+Claude Desktop → mcp-remote → Railway (HTTPS) → n8n-MCP Server
+```
+
+1. **Claude Desktop** uses `mcp-remote` as a bridge
+2. **mcp-remote** converts stdio to HTTP requests
+3. **Railway** provides HTTPS endpoint and infrastructure
+4. **n8n-MCP** runs in HTTP mode on Railway
+
+### Single-Instance Design
+
+**Important**: The n8n-MCP HTTP server is designed for single n8n instance deployment:
+- n8n API credentials are configured server-side via environment variables
+- All clients connecting to the server share the same n8n instance
+- For multi-tenant usage, deploy separate Railway instances
+
+### Security Model
+
+- **Bearer Token Authentication**: All requests require the AUTH_TOKEN
+- **HTTPS by Default**: Railway provides SSL certificates
+- **Environment Isolation**: Each deployment is isolated
+- **No State Storage**: Server is stateless (database is read-only)
+
+## 🚨 Troubleshooting
+
+### Connection Issues
+
+**"Invalid URL" error in Claude Desktop:**
+- Ensure you're using the exact configuration format shown above
+- Don't add "connect" or other arguments before the URL
+- The URL should end with `/mcp`
+
+**"Unauthorized" error:**
+- Check that your AUTH_TOKEN matches exactly (no extra spaces)
+- Ensure the Authorization header format is correct: `Authorization: Bearer TOKEN`
+
+**"Cannot connect to server":**
+- Verify your Railway deployment is running (check Railway dashboard)
+- Ensure the URL is correct and includes `https://`
+- Check Railway logs for any errors
+
+### Railway-Specific Issues
+
+**Build failures:**
+- Railway uses AMD64 architecture - the template is configured for this
+- Check build logs in Railway dashboard for specific errors
+
+**Environment variable issues:**
+- Variables are case-sensitive
+- Don't include quotes in the Railway dashboard (only in JSON config)
+- Railway automatically restarts when you change variables
+
+**Domain not working:**
+- It may take 1-2 minutes for the domain to become active
+- Check the "Deployments" tab to ensure the latest deployment succeeded
+
+## 📊 Monitoring & Logs
+
+### View Logs
+
+1. Go to Railway dashboard
+2. Click on your n8n-mcp service
+3. Click on **"Logs"** tab
+4. You'll see real-time logs including:
+   - Server startup messages
+   - Authentication attempts
+   - API requests (without sensitive data)
+   - Any errors or warnings
+
+### Monitor Usage
+
+Railway provides metrics for:
+- **Memory usage** (typically ~100-200MB)
+- **CPU usage** (minimal when idle)
+- **Network traffic**
+- **Response times**
+
+## 💰 Pricing & Limits
+
+### Railway Free Tier
+- **$5 free credit** monthly
+- **500 hours** of runtime
+- **Sufficient for personal use** of n8n-MCP
+
+### Estimated Costs
+- **n8n-MCP typically uses**: ~0.1 GB RAM
+- **Monthly cost**: ~$2-3 for 24/7 operation
+- **Well within free tier** for most users
+
+## 🔄 Updates & Maintenance
+
+### Manual Updates
+
+Since the Railway template uses a specific Docker image tag, updates are manual:
+
+1. **Check for updates** on [GitHub](https://github.com/czlonkowski/n8n-mcp)
+2. **Update image tag** in Railway:
+   - Go to Settings → Deploy → Docker Image
+   - Change tag from current to new version
+   - Click "Redeploy"
+
+### Automatic Updates (Not Recommended)
+
+You could use the `latest` tag, but this may cause unexpected breaking changes.
+
+## 📝 Best Practices
+
+1. **Always change the default AUTH_TOKEN immediately**
+2. **Use strong, unique tokens** (32+ characters)
+3. **Monitor logs** for unauthorized access attempts
+4. **Keep credentials secure** - never commit them to git
+5. **Use environment variables** for all sensitive data
+6. **Regular updates** - check for new versions monthly
+

+# Visual Studio Code Setup
+
+:white_check_mark: This n8n MCP server is compatible with VS Code + GitHub Copilot (Chat in IDE).
+
+## Preconditions
+
+Assuming you've already deployed the n8n MCP server and connected it to the n8n API, and it's available at:
+`https://n8n.your.production.url/`
+
+💡 The deployment process is documented in the [HTTP Deployment Guide](./HTTP_DEPLOYMENT.md).
+
+## Step 1
+
+Start by creating a new VS Code project folder.
+
+## Step 2
+
+Create a file: `.vscode/mcp.json`
+```json
+{
+    "inputs": [
+        {
+            "type": "promptString",
+            "id": "n8n-mcp-token",
+            "description": "Your n8n-MCP AUTH_TOKEN",
+            "password": true
+        }
+    ],
+    "servers": {
+        "n8n-mcp": {
+            "type": "http",
+            "url": "https://n8n.your.production.url/mcp",
+            "headers": {
+                "Authorization": "Bearer ${input:n8n-mcp-token}"
+            }
+        }
+    }
+}
+```
+
+💡 The `inputs` block ensures the token is requested interactively — no need to hardcode secrets.
+
+## Step 3
+
+GitHub Copilot does not provide access to "thinking models" for unpaid users. To improve results, install the official [Sequential Thinking MCP server](https://github.com/modelcontextprotocol/servers/tree/main/src/sequentialthinking) referenced in the [VS Code docs](https://code.visualstudio.com/mcp#:~:text=Install%20Linear-,Sequential%20Thinking,-Model%20Context%20Protocol). This lightweight add-on can turn any LLM into a thinking model by enabling step-by-step reasoning. It's highly recommended to use the n8n-mcp server in combination with a sequential thinking model to generate more accurate outputs.
+
+🔧 Alternatively, you can try enabling this setting in Copilot to unlock "thinking mode" behavior:
+
+![VS Code Settings > GitHub > Copilot > Chat > Agent: Thinking Tool](./img/vsc_ghcp_chat_thinking_tool.png)
+
+_(Note: I haven’t tested this setting myself, as I use the Sequential Thinking MCP instead)_
+
+## Step 4
+
+For the best results when using n8n-MCP with VS Code, use these enhanced system instructions (copy to your project’s `.github/copilot-instructions.md`):
+
+```markdown
+You are an expert in n8n automation software using n8n-MCP tools. Your role is to design, build, and validate n8n workflows with maximum accuracy and efficiency.
+
+## Core Workflow Process
+
+1. **ALWAYS start new conversation with**: `tools_documentation()` to understand best practices and available tools.
+
+2. **Discovery Phase** - Find the right nodes:
+   - Think deeply about user request and the logic you are going to build to fulfill it. Ask follow-up questions to clarify the user's intent, if something is unclear. Then, proceed with the rest of your instructions.
+   - `search_nodes({query: 'keyword'})` - Search by functionality
+   - `list_nodes({category: 'trigger'})` - Browse by category
+   - `list_ai_tools()` - See AI-capable nodes (remember: ANY node can be an AI tool!)
+
+3. **Configuration Phase** - Get node details efficiently:
+   - `get_node_essentials(nodeType)` - Start here! Only 10-20 essential properties
+   - `search_node_properties(nodeType, 'auth')` - Find specific properties
+   - `get_node_for_task('send_email')` - Get pre-configured templates
+   - `get_node_documentation(nodeType)` - Human-readable docs when needed
+   - It is good common practice to show a visual representation of the workflow architecture to the user and asking for opinion, before moving forward. 
+
+4. **Pre-Validation Phase** - Validate BEFORE building:
+   - `validate_node_minimal(nodeType, config)` - Quick required fields check
+   - `validate_node_operation(nodeType, config, profile)` - Full operation-aware validation
+   - Fix any validation errors before proceeding
+
+5. **Building Phase** - Create the workflow:
+   - Use validated configurations from step 4
+   - Connect nodes with proper structure
+   - Add error handling where appropriate
+   - Use expressions like $json, $node["NodeName"].json
+   - Build the workflow in an artifact for easy editing downstream (unless the user asked to create in n8n instance)
+
+6. **Workflow Validation Phase** - Validate complete workflow:
+   - `validate_workflow(workflow)` - Complete validation including connections
+   - `validate_workflow_connections(workflow)` - Check structure and AI tool connections
+   - `validate_workflow_expressions(workflow)` - Validate all n8n expressions
+   - Fix any issues found before deployment
+
+7. **Deployment Phase** (if n8n API configured):
+   - `n8n_create_workflow(workflow)` - Deploy validated workflow
+   - `n8n_validate_workflow({id: 'workflow-id'})` - Post-deployment validation
+   - `n8n_update_partial_workflow()` - Make incremental updates using diffs
+   - `n8n_trigger_webhook_workflow()` - Test webhook workflows
+
+## Key Insights
+
+- **USE CODE NODE ONLY WHEN IT IS NECESSARY** - always prefer to use standard nodes over code node. Use code node only when you are sure you need it.
+- **VALIDATE EARLY AND OFTEN** - Catch errors before they reach deployment
+- **USE DIFF UPDATES** - Use n8n_update_partial_workflow for 80-90% token savings
+- **ANY node can be an AI tool** - not just those with usableAsTool=true
+- **Pre-validate configurations** - Use validate_node_minimal before building
+- **Post-validate workflows** - Always validate complete workflows before deployment
+- **Incremental updates** - Use diff operations for existing workflows
+- **Test thoroughly** - Validate both locally and after deployment to n8n
+
+## Validation Strategy
+
+### Before Building:
+1. validate_node_minimal() - Check required fields
+2. validate_node_operation() - Full configuration validation
+3. Fix all errors before proceeding
+
+### After Building:
+1. validate_workflow() - Complete workflow validation
+2. validate_workflow_connections() - Structure validation
+3. validate_workflow_expressions() - Expression syntax check
+
+### After Deployment:
+1. n8n_validate_workflow({id}) - Validate deployed workflow
+2. n8n_list_executions() - Monitor execution status
+3. n8n_update_partial_workflow() - Fix issues using diffs
+
+## Response Structure
+
+1. **Discovery**: Show available nodes and options
+2. **Pre-Validation**: Validate node configurations first
+3. **Configuration**: Show only validated, working configs
+4. **Building**: Construct workflow with validated components
+5. **Workflow Validation**: Full workflow validation results
+6. **Deployment**: Deploy only after all validations pass
+7. **Post-Validation**: Verify deployment succeeded
+
+## Example Workflow
+
+### 1. Discovery & Configuration
+search_nodes({query: 'slack'})
+get_node_essentials('n8n-nodes-base.slack')
+
+### 2. Pre-Validation
+validate_node_minimal('n8n-nodes-base.slack', {resource:'message', operation:'send'})
+validate_node_operation('n8n-nodes-base.slack', fullConfig, 'runtime')
+
+### 3. Build Workflow
+// Create workflow JSON with validated configs
+
+### 4. Workflow Validation
+validate_workflow(workflowJson)
+validate_workflow_connections(workflowJson)
+validate_workflow_expressions(workflowJson)
+
+### 5. Deploy (if configured)
+n8n_create_workflow(validatedWorkflow)
+n8n_validate_workflow({id: createdWorkflowId})
+
+### 6. Update Using Diffs
+n8n_update_partial_workflow({
+  workflowId: id,
+  operations: [
+    {type: 'updateNode', nodeId: 'slack1', changes: {position: [100, 200]}}
+  ]
+})
+
+## Important Rules
+
+- ALWAYS validate before building
+- ALWAYS validate after building
+- NEVER deploy unvalidated workflows
+- USE diff operations for updates (80-90% token savings)
+- STATE validation results clearly
+- FIX all errors before proceeding
+```
+
+This helps the agent produce higher-quality, well-structured n8n workflows.
+
+🔧 Important: To ensure the instructions are always included, make sure this checkbox is enabled in your Copilot settings:
+
+![VS Code Settings > GitHub > Copilot > Chat > Code Generation: Use Instruction Files](./img/vsc_ghcp_chat_instruction_files.png)
+
+## Step 5
+
+Switch GitHub Copilot to Agent mode:
+
+![VS Code > GitHub Copilot Chat > Edit files in your workspace in agent mode](./img/vsc_ghcp_chat_agent_mode.png)
+
+## Step 6 - Try it!
+
+Here’s an example prompt I used:
+```
+#fetch https://blog.n8n.io/rag-chatbot/
+
+use #sequentialthinking and #n8n-mcp tools to build a new n8n workflow step-by-step following the guidelines in the blog.
+In the end, please deploy a fully-functional n8n workflow.
+```
+
+🧪 My result wasn’t perfect (a bit messy workflow), but I'm genuinely happy that it created anything autonomously 😄 Stay tuned for updates!

+# Issue #90: "propertyValues[itemName] is not iterable" Error - Research Findings
+
+## Executive Summary
+
+The error "propertyValues[itemName] is not iterable" occurs when AI agents create workflows with incorrect data structures for n8n nodes that use `fixedCollection` properties. This primarily affects Switch Node v2, If Node, and Filter Node. The error prevents workflows from loading in the n8n UI, resulting in empty canvases.
+
+## Root Cause Analysis
+
+### 1. Data Structure Mismatch
+
+The error occurs when n8n's validation engine expects an iterable array but encounters a non-iterable object. This happens with nodes using `fixedCollection` type properties.
+
+**Incorrect Structure (causes error):**
+```json
+{
+  "rules": {
+    "conditions": {
+      "values": [
+        {
+          "value1": "={{$json.status}}",
+          "operation": "equals", 
+          "value2": "active"
+        }
+      ]
+    }
+  }
+}
+```
+
+**Correct Structure:**
+```json
+{
+  "rules": {
+    "conditions": [
+      {
+        "value1": "={{$json.status}}",
+        "operation": "equals",
+        "value2": "active"
+      }
+    ]
+  }
+}
+```
+
+### 2. Affected Nodes
+
+Based on the research and issue comments, the following nodes are affected:
+
+1. **Switch Node v2** (`n8n-nodes-base.switch` with typeVersion: 2)
+   - Uses `rules` parameter with `conditions` fixedCollection
+   - v3 doesn't have this issue due to restructured schema
+
+2. **If Node** (`n8n-nodes-base.if` with typeVersion: 1)
+   - Uses `conditions` parameter with nested conditions array
+   - Similar structure to Switch v2
+
+3. **Filter Node** (`n8n-nodes-base.filter`)
+   - Uses `conditions` parameter
+   - Same fixedCollection pattern
+
+### 3. Why AI Agents Create Incorrect Structures
+
+1. **Training Data Issues**: AI models may have been trained on outdated or incorrect n8n workflow examples
+2. **Nested Object Inference**: AI tends to create unnecessarily nested structures when it sees collection-type parameters
+3. **Legacy Format Confusion**: Mixing v2 and v3 Switch node formats
+4. **Schema Misinterpretation**: The term "fixedCollection" may lead AI to create object wrappers
+
+## Current Impact
+
+From issue #90 comments:
+- Multiple users experiencing the issue
+- Workflows fail to load completely (empty canvas)
+- Users resort to using Switch Node v3 or direct API calls
+- The issue appears in "most MCPs" according to user feedback
+
+## Recommended Actions
+
+### 1. Immediate Validation Enhancement
+
+Add specific validation for fixedCollection properties in the workflow validator:
+
+```typescript
+// In workflow-validator.ts or enhanced-config-validator.ts
+function validateFixedCollectionParameters(node, result) {
+  const problematicNodes = {
+    'n8n-nodes-base.switch': { version: 2, fields: ['rules'] },
+    'n8n-nodes-base.if': { version: 1, fields: ['conditions'] },
+    'n8n-nodes-base.filter': { version: 1, fields: ['conditions'] }
+  };
+  
+  const nodeConfig = problematicNodes[node.type];
+  if (nodeConfig && node.typeVersion === nodeConfig.version) {
+    // Validate structure
+  }
+}
+```
+
+### 2. Enhanced MCP Tool Validation
+
+Update the validation tools to detect and prevent this specific error pattern:
+
+1. **In `validate_node_operation` tool**: Add checks for fixedCollection structures
+2. **In `validate_workflow` tool**: Include specific validation for Switch/If nodes
+3. **In `n8n_create_workflow` tool**: Pre-validate parameters before submission
+
+### 3. AI-Friendly Examples
+
+Update workflow examples to show correct structures:
+
+```typescript
+// In workflow-examples.ts
+export const SWITCH_NODE_EXAMPLE = {
+  name: "Switch",
+  type: "n8n-nodes-base.switch", 
+  typeVersion: 3, // Prefer v3 over v2
+  parameters: {
+    // Correct v3 structure
+  }
+};
+```
+
+### 4. Migration Strategy
+
+For existing workflows with Switch v2:
+1. Detect Switch v2 nodes in validation
+2. Suggest migration to v3
+3. Provide automatic conversion utility
+
+### 5. Documentation Updates
+
+1. Add warnings about fixedCollection structures in tool documentation
+2. Include specific examples of correct vs incorrect structures
+3. Document the Switch v2 to v3 migration path
+
+## Proposed Implementation Priority
+
+1. **High Priority**: Add validation to prevent creation of invalid structures
+2. **High Priority**: Update existing validation tools to catch this error
+3. **Medium Priority**: Add auto-fix capabilities to correct structures
+4. **Medium Priority**: Update examples and documentation
+5. **Low Priority**: Create migration utilities for v2 to v3
+
+## Testing Strategy
+
+1. Create test cases for each affected node type
+2. Test both correct and incorrect structures
+3. Verify validation catches all variants of the error
+4. Test auto-fix suggestions work correctly
+
+## Success Metrics
+
+- Zero instances of "propertyValues[itemName] is not iterable" in newly created workflows
+- Clear error messages that guide users to correct structures
+- Successful validation of all Switch/If node configurations before workflow creation
+
+## Next Steps
+
+1. Implement validation enhancements in the workflow validator
+2. Update MCP tools to include these validations
+3. Add comprehensive tests
+4. Update documentation with clear examples
+5. Consider adding a migration tool for existing workflows

+# n8n MCP Client Tool Integration - Implementation Plan (Simplified)
+
+## Overview
+
+This document provides a **simplified** implementation plan for making n8n-mcp compatible with n8n's MCP Client Tool (v1.1). Based on expert review, we're taking a minimal approach that extends the existing single-session server rather than creating new architecture.
+
+## Key Design Principles
+
+1. **Minimal Changes**: Extend existing single-session server with n8n compatibility mode
+2. **No Overengineering**: No complex session management or multi-session architecture
+3. **Docker-Native**: Separate Docker image for n8n deployment
+4. **Remote Deployment**: Designed to run alongside n8n in production
+5. **Backward Compatible**: Existing functionality remains unchanged
+
+## Prerequisites
+
+- Docker and Docker Compose
+- n8n version 1.104.2 or higher (with MCP Client Tool v1.1)
+- Basic understanding of Docker networking
+
+## Implementation Approach
+
+Instead of creating new multi-session architecture, we'll extend the existing single-session server with an n8n compatibility mode. This approach was recommended by all three expert reviewers as simpler and more maintainable.
+
+## Architecture Changes
+
+```
+src/
+├── http-server-single-session.ts  # MODIFY: Add n8n mode flag
+└── mcp/
+    └── server.ts                  # NO CHANGES NEEDED
+
+Docker/
+├── Dockerfile.n8n                 # NEW: n8n-specific image
+├── docker-compose.n8n.yml         # NEW: Simplified stack
+└── .github/workflows/
+    └── docker-build-n8n.yml       # NEW: Build workflow
+```
+
+## Implementation Steps
+
+### Step 1: Modify Existing Single-Session Server
+
+#### 1.1 Update `src/http-server-single-session.ts`
+
+Add n8n compatibility mode to the existing server with minimal changes:
+
+```typescript
+// Add these constants at the top (after imports)
+const PROTOCOL_VERSION = "2024-11-05";
+const N8N_MODE = process.env.N8N_MODE === 'true';
+
+// In the constructor or start method, add logging
+if (N8N_MODE) {
+  logger.info('Running in n8n compatibility mode');
+}
+
+// In setupRoutes method, add the protocol version endpoint
+if (N8N_MODE) {
+  app.get('/mcp', (req, res) => {
+    res.json({
+      protocolVersion: PROTOCOL_VERSION,
+      serverInfo: {
+        name: "n8n-mcp",
+        version: PROJECT_VERSION,
+        capabilities: {
+          tools: true,
+          resources: false,
+          prompts: false,
+        },
+      },
+    });
+  });
+}
+
+// In handleMCPRequest method, add session header
+if (N8N_MODE && this.session) {
+  res.setHeader('Mcp-Session-Id', this.session.sessionId);
+}
+
+// Update error handling to use JSON-RPC format
+catch (error) {
+  logger.error('MCP request error:', error);
+  
+  if (N8N_MODE) {
+    res.status(500).json({
+      jsonrpc: '2.0',
+      error: {
+        code: -32603,
+        message: 'Internal error',
+        data: error instanceof Error ? error.message : 'Unknown error',
+      },
+      id: null,
+    });
+  } else {
+    // Keep existing error handling for backward compatibility
+    res.status(500).json({ 
+      error: 'Internal server error',
+      details: error instanceof Error ? error.message : 'Unknown error'
+    });
+  }
+}
+```
+
+That's it! No new files, no complex session management. Just a few lines of code.
+
+### Step 2: Update Package Scripts
+
+#### 2.1 Update `package.json`
+
+Add a simple script for n8n mode:
+
+```json
+{
+  "scripts": {
+    "start:n8n": "N8N_MODE=true MCP_MODE=http node dist/mcp/index.js"
+  }
+}
+```
+
+### Step 3: Create Docker Infrastructure for n8n
+
+#### 3.1 Create `Dockerfile.n8n`
+
+```dockerfile
+# Dockerfile.n8n - Optimized for n8n integration
+FROM node:22-alpine AS builder
+
+WORKDIR /app
+
+# Install build dependencies
+RUN apk add --no-cache python3 make g++
+
+# Copy package files
+COPY package*.json tsconfig*.json ./
+
+# Install ALL dependencies
+RUN npm ci --no-audit --no-fund
+
+# Copy source and build
+COPY src ./src
+RUN npm run build && npm run rebuild
+
+# Runtime stage
+FROM node:22-alpine
+
+WORKDIR /app
+
+# Install runtime dependencies
+RUN apk add --no-cache curl dumb-init
+
+# Create non-root user
+RUN addgroup -g 1001 -S nodejs && adduser -S nodejs -u 1001
+
+# Copy application from builder
+COPY --from=builder --chown=nodejs:nodejs /app/dist ./dist
+COPY --from=builder --chown=nodejs:nodejs /app/data ./data
+COPY --from=builder --chown=nodejs:nodejs /app/node_modules ./node_modules
+COPY --chown=nodejs:nodejs package.json ./
+
+USER nodejs
+
+EXPOSE 3001
+
+HEALTHCHECK CMD curl -f http://localhost:3001/health || exit 1
+
+ENTRYPOINT ["dumb-init", "--"]
+CMD ["node", "dist/mcp/index.js"]
+```
+
+#### 3.2 Create `docker-compose.n8n.yml`
+
+```yaml
+# docker-compose.n8n.yml - Simple stack for n8n + n8n-mcp
+version: '3.8'
+
+services:

+      - N8N_BASIC_AUTH_USER=${N8N_USER:-admin}
+      - N8N_BASIC_AUTH_PASSWORD=${N8N_PASSWORD:-changeme}
+      - N8N_COMMUNITY_PACKAGES_ALLOW_TOOL_USAGE=true
+    volumes:
+      - n8n_data:/home/node/.n8n
+    networks:
+      - n8n-net
+    depends_on:
+      n8n-mcp:
+        condition: service_healthy
+
+  n8n-mcp:
+    image: ghcr.io/${GITHUB_USER:-czlonkowski}/n8n-mcp-n8n:latest
+    build:
+      context: .
+      dockerfile: Dockerfile.n8n
+    container_name: n8n-mcp
+    restart: unless-stopped
+    environment:
+      - MCP_MODE=http
+      - N8N_MODE=true
+      - AUTH_TOKEN=${MCP_AUTH_TOKEN}
+      - NODE_ENV=production
+      - HTTP_PORT=3001
+    networks:
+      - n8n-net
+    healthcheck:
+      test: ["CMD", "curl", "-f", "http://localhost:3001/health"]
+      interval: 30s
+      timeout: 10s
+      retries: 3
+
+networks:
+  n8n-net:
+    driver: bridge
+
+volumes:
+  n8n_data:
+```
+
+#### 3.3 Create `.env.n8n.example`
+
+```bash
+# .env.n8n.example - Copy to .env and configure
+
+# n8n Configuration
+N8N_USER=admin
+N8N_PASSWORD=changeme
+N8N_BASIC_AUTH_ACTIVE=true
+
+# MCP Configuration
+# Generate with: openssl rand -base64 32
+MCP_AUTH_TOKEN=your-secure-token-minimum-32-characters
+
+# GitHub username for image registry
+GITHUB_USER=czlonkowski
+```
+
+### Step 4: Create GitHub Actions Workflow
+
+#### 4.1 Create `.github/workflows/docker-build-n8n.yml`
+
+```yaml
+name: Build n8n Docker Image
+
+on:
+  push:
+    branches: [main]
+    tags: ['v*']
+    paths:
+      - 'src/**'
+      - 'package*.json'
+      - 'Dockerfile.n8n'
+  workflow_dispatch:
+
+env:
+  REGISTRY: ghcr.io
+  IMAGE_NAME: ${{ github.repository }}-n8n
+
+jobs:

+          tags: |
+            type=ref,event=branch
+            type=semver,pattern={{version}}
+            type=raw,value=latest,enable={{is_default_branch}}
+            
+      - uses: docker/build-push-action@v5
+        with:
+          context: .
+          file: ./Dockerfile.n8n
+          push: true
+          tags: ${{ steps.meta.outputs.tags }}
+          cache-from: type=gha
+          cache-to: type=gha,mode=max
+```
+
+### Step 5: Testing
+
+#### 5.1 Unit Tests for n8n Mode
+
+Create `tests/unit/http-server-n8n-mode.test.ts`:
+
+```typescript
+import { describe, it, expect, vi } from 'vitest';
+import request from 'supertest';
+
+describe('n8n Mode', () => {
+  it('should return protocol version on GET /mcp', async () => {
+    process.env.N8N_MODE = 'true';
+    const app = await createTestApp();
+    
+    const response = await request(app)
+      .get('/mcp')
+      .expect(200);
+    
+    expect(response.body.protocolVersion).toBe('2024-11-05');
+    expect(response.body.serverInfo.capabilities.tools).toBe(true);
+  });
+  
+  it('should include session ID in response headers', async () => {
+    process.env.N8N_MODE = 'true';
+    const app = await createTestApp();
+    
+    const response = await request(app)
+      .post('/mcp')
+      .set('Authorization', 'Bearer test-token')
+      .send({ jsonrpc: '2.0', method: 'initialize', id: 1 });
+    
+    expect(response.headers['mcp-session-id']).toBeDefined();
+  });
+  
+  it('should format errors as JSON-RPC', async () => {
+    process.env.N8N_MODE = 'true';
+    const app = await createTestApp();
+    
+    const response = await request(app)
+      .post('/mcp')
+      .send({ invalid: 'request' })
+      .expect(500);
+    
+    expect(response.body.jsonrpc).toBe('2.0');
+    expect(response.body.error.code).toBe(-32603);
+  });
+});
+```
+
+#### 5.2 Quick Deployment Script
+
+Create `deploy/quick-deploy-n8n.sh`:
+
+```bash
+#!/bin/bash
+set -e
+
+echo "🚀 Quick Deploy n8n + n8n-mcp"
+
+# Check prerequisites
+command -v docker >/dev/null 2>&1 || { echo "Docker required"; exit 1; }
+command -v docker-compose >/dev/null 2>&1 || { echo "Docker Compose required"; exit 1; }
+
+# Generate auth token if not exists
+if [ ! -f .env ]; then
+  cp .env.n8n.example .env
+  TOKEN=$(openssl rand -base64 32)
+  sed -i "s/your-secure-token-minimum-32-characters/$TOKEN/" .env
+  echo "Generated MCP_AUTH_TOKEN: $TOKEN"
+fi
+
+# Deploy
+docker-compose -f docker-compose.n8n.yml up -d
+
+echo ""
+echo "✅ Deployment complete!"
+echo ""
+echo "📋 Next steps:"
+echo "1. Access n8n at http://localhost:5678"
+echo "   Username: admin (or check .env)"
+echo "   Password: changeme (or check .env)"
+echo ""
+echo "2. Create a workflow with MCP Client Tool:"
+echo "   - Server URL: http://n8n-mcp:3001/mcp"
+echo "   - Authentication: Bearer Token"
+echo "   - Token: Check .env file for MCP_AUTH_TOKEN"
+echo ""
+echo "📊 View logs: docker-compose -f docker-compose.n8n.yml logs -f"
+echo "🛑 Stop: docker-compose -f docker-compose.n8n.yml down"
+```

+
+## Quick Start Guide
+
+### 1. One-Command Deployment
+
+```bash
+# Clone and deploy
+git clone https://github.com/czlonkowski/n8n-mcp.git
+cd n8n-mcp
+./deploy/quick-deploy-n8n.sh
+```
+
+### 2. Manual Configuration in n8n
+
+After deployment, configure the MCP Client Tool in n8n:
+
+1. Open n8n at `http://localhost:5678`
+2. Create a new workflow
+3. Add "MCP Client Tool" node (under AI category)
+4. Configure:
+   - **Server URL**: `http://n8n-mcp:3001/mcp`
+   - **Authentication**: Bearer Token
+   - **Token**: Check your `.env` file for MCP_AUTH_TOKEN
+5. Select a tool (e.g., `list_nodes`)
+6. Execute the workflow
+
+### 3. Production Deployment
+
+For production with SSL, use a reverse proxy:
+
+```nginx
+# nginx configuration
+server {
+    listen 443 ssl;
+    server_name n8n.yourdomain.com;
+    
+    location / {
+        proxy_pass http://localhost:5678;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "upgrade";
+    }
+}
+```
+
+The MCP server should remain internal only - n8n connects via Docker network.
+
+## Success Criteria
+
+The implementation is successful when:
+
+1. **Minimal Code Changes**: Only ~20 lines added to existing server
+2. **Protocol Compliance**: GET /mcp returns correct protocol version
+3. **n8n Connection**: MCP Client Tool connects successfully
+4. **Tool Execution**: Tools work without modification
+5. **Backward Compatible**: Existing Claude Desktop usage unaffected
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"Protocol version mismatch"**
+   - Ensure N8N_MODE=true is set
+   - Check GET /mcp returns "2024-11-05"
+
+2. **"Authentication failed"**
+   - Verify AUTH_TOKEN matches in .env and n8n
+   - Token must be 32+ characters
+   - Use "Bearer Token" auth type in n8n
+
+3. **"Connection refused"**
+   - Check containers are on same network
+   - Use internal hostname: `http://n8n-mcp:3001/mcp`
+   - Verify health check passes
+
+4. **Testing the Setup**
+   ```bash
+   # Check protocol version
+   docker exec n8n-mcp curl http://localhost:3001/mcp
+

+   docker-compose -f docker-compose.n8n.yml logs -f n8n-mcp
+   ```
+
+## Summary
+
+This simplified approach:
+- **Extends existing code** rather than creating new architecture
+- **Adds n8n compatibility** with minimal changes
+- **Uses separate Docker image** for clean deployment
+- **Maintains backward compatibility** for existing users
+- **Avoids overengineering** with simple, practical solutions
+
+Total implementation effort: ~2-3 hours (vs. 2-3 days for multi-session approach)

+# Test Artifacts Documentation
+
+This document describes the comprehensive test result artifact storage system implemented in the n8n-mcp project.
+
+## Overview
+
+The test artifact system captures, stores, and presents test results in multiple formats to facilitate debugging, analysis, and historical tracking of test performance.
+
+## Artifact Types
+
+### 1. Test Results
+- **JUnit XML** (`test-results/junit.xml`): Standard format for CI integration
+- **JSON Results** (`test-results/results.json`): Detailed test data for analysis
+- **HTML Report** (`test-results/html/index.html`): Interactive test report
+- **Test Summary** (`test-summary.md`): Markdown summary for PR comments
+
+### 2. Coverage Reports
+- **LCOV** (`coverage/lcov.info`): Standard coverage format
+- **HTML Coverage** (`coverage/html/index.html`): Interactive coverage browser
+- **Coverage Summary** (`coverage/coverage-summary.json`): JSON coverage data
+
+### 3. Benchmark Results
+- **Benchmark JSON** (`benchmark-results.json`): Raw benchmark data
+- **Comparison Reports** (`benchmark-comparison.md`): PR benchmark comparisons
+
+### 4. Detailed Reports
+- **HTML Report** (`test-reports/report.html`): Comprehensive styled report
+- **Markdown Report** (`test-reports/report.md`): Full markdown report
+- **JSON Report** (`test-reports/report.json`): Complete test data
+
+## GitHub Actions Integration
+
+### Test Workflow (`test.yml`)
+
+The main test workflow:
+1. Runs tests with coverage using multiple reporters
+2. Generates test summaries and detailed reports
+3. Uploads artifacts with metadata
+4. Posts summaries to PRs
+5. Creates a combined artifact index
+
+### Benchmark PR Workflow (`benchmark-pr.yml`)
+
+For pull requests:
+1. Runs benchmarks on PR branch
+2. Runs benchmarks on base branch
+3. Compares results
+4. Posts comparison to PR
+5. Sets status checks for regressions
+
+## Artifact Retention
+
+- **Test Results**: 30 days
+- **Coverage Reports**: 30 days
+- **Benchmark Results**: 30 days
+- **Combined Results**: 90 days
+- **Test Metadata**: 30 days
+
+## PR Comment Integration
+
+The system automatically:
+- Posts test summaries to PR comments
+- Updates existing comments instead of creating duplicates
+- Includes links to full artifacts
+- Shows coverage and benchmark changes
+
+## Job Summary
+
+Each workflow run includes a job summary with:
+- Test results overview
+- Coverage summary
+- Benchmark results
+- Direct links to download artifacts
+
+## Local Development
+
+### Running Tests with Reports
+
+```bash
+# Run tests with all reporters
+CI=true npm run test:coverage
+
+# Generate detailed reports
+node scripts/generate-detailed-reports.js
+
+# Generate test summary
+node scripts/generate-test-summary.js
+
+# Compare benchmarks
+node scripts/compare-benchmarks.js benchmark-results.json benchmark-baseline.json
+```
+
+### Report Locations
+
+When running locally, reports are generated in:
+- `test-results/` - Vitest outputs
+- `test-reports/` - Detailed reports
+- `coverage/` - Coverage reports
+- Root directory - Summary files
+
+## Report Formats
+
+### HTML Report Features
+- Responsive design
+- Test suite breakdown
+- Failed test details with error messages
+- Coverage visualization with progress bars
+- Benchmark performance metrics
+- Sortable tables
+
+### Markdown Report Features
+- GitHub-compatible formatting
+- Summary statistics
+- Failed test listings
+- Coverage breakdown
+- Benchmark comparisons
+
+### JSON Report Features
+- Complete test data
+- Programmatic access
+- Historical comparison
+- CI/CD integration
+
+## Best Practices
+
+1. **Always Check Artifacts**: When tests fail in CI, download and review the HTML report
+2. **Monitor Coverage**: Use the coverage reports to identify untested code
+3. **Track Benchmarks**: Review benchmark comparisons on performance-critical PRs
+4. **Archive Important Runs**: Download artifacts from significant releases
+
+## Troubleshooting
+
+### Missing Artifacts
+- Check if tests ran to completion
+- Verify artifact upload steps executed
+- Check retention period hasn't expired
+
+### Report Generation Failures
+- Ensure all dependencies are installed
+- Check for valid test/coverage output files
+- Review workflow logs for errors
+
+### PR Comment Issues
+- Verify GitHub Actions permissions
+- Check bot authentication
+- Review comment posting logs

+```
+
+## Mock Strategy
+
+### 1. Mock Service Worker (MSW) for API Mocking
+
+We use MSW for intercepting and mocking HTTP requests:
+
+```typescript
+// tests/mocks/n8n-api/handlers.ts
+import { http, HttpResponse } from 'msw';
+
+export const handlers = [
+  // Workflow endpoints
+  http.get('*/workflows/:id', ({ params }) => {
+    const workflow = mockWorkflows.find(w => w.id === params.id);
+    if (!workflow) {
+      return new HttpResponse(null, { status: 404 });
+    }
+    return HttpResponse.json(workflow);
+  }),
+
+  // Execution endpoints
+  http.post('*/workflows/:id/run', async ({ params, request }) => {
+    const body = await request.json();
+    return HttpResponse.json({
+      executionId: generateExecutionId(),
+      status: 'running'
+    });
+  })
+];
+```
+
+### 2. Database Mocking
+
+For unit tests, we mock the database layer:
+
+```typescript
+// tests/unit/__mocks__/better-sqlite3.ts
+import { vi } from 'vitest';
+
+export default vi.fn(() => ({
+  prepare: vi.fn(() => ({
+    all: vi.fn().mockReturnValue([]),
+    get: vi.fn().mockReturnValue(undefined),
+    run: vi.fn().mockReturnValue({ changes: 1 }),
+    finalize: vi.fn()
+  })),
+  exec: vi.fn(),
+  close: vi.fn(),
+  pragma: vi.fn()
+}));
+```
+
+### 3. MCP SDK Mocking
+
+For testing MCP protocol interactions:
+
+```typescript
+// tests/integration/mcp-protocol/test-helpers.ts
+export class TestableN8NMCPServer extends N8NMCPServer {
+  private transports = new Set<Transport>();
+  
+  async connectToTransport(transport: Transport): Promise<void> {
+    this.transports.add(transport);
+    await this.connect(transport);
+  }
+  
+  async close(): Promise<void> {
+    for (const transport of this.transports) {
+      await transport.close();
+    }
+    this.transports.clear();
+  }
+}
+```
+
+## Test Patterns and Utilities
+
+### 1. Database Test Utilities
+
+```typescript
+// tests/utils/database-utils.ts
+export class TestDatabase {
+  constructor(options: TestDatabaseOptions = {}) {
+    this.options = {
+      mode: 'memory',
+      enableFTS5: true,
+      ...options
+    };
+  }
+
+  async initialize(): Promise<Database.Database> {
+    const db = this.options.mode === 'memory' 
+      ? new Database(':memory:') 
+      : new Database(this.dbPath);
+    
+    if (this.options.enableFTS5) {
+      await this.enableFTS5(db);
+    }
+    
+    return db;
+  }
+}
+```
+
+### 2. Data Generators
+
+```typescript
+// tests/utils/data-generators.ts
+export class TestDataGenerator {
+  static generateNode(overrides: Partial<ParsedNode> = {}): ParsedNode {
+    return {
+      nodeType: `test.node${faker.number.int()}`,
+      displayName: faker.commerce.productName(),
+      description: faker.lorem.sentence(),
+      properties: this.generateProperties(5),
+      ...overrides
+    };
+  }
+
+  static generateWorkflow(nodeCount = 3): any {
+    const nodes = Array.from({ length: nodeCount }, (_, i) => ({
+      id: `node_${i}`,
+      type: 'test.node',
+      position: [i * 100, 0],
+      parameters: {}
+    }));
+    
+    return { nodes, connections: {} };
+  }
+}
+```
+
+### 3. Custom Assertions
+
+```typescript
+// tests/utils/assertions.ts
+export function expectValidMCPResponse(response: any): void {
+  expect(response).toBeDefined();
+  expect(response.content).toBeDefined();
+  expect(Array.isArray(response.content)).toBe(true);
+  expect(response.content[0]).toHaveProperty('type', 'text');
+  expect(response.content[0]).toHaveProperty('text');
+}
+
+export function expectNodeStructure(node: any): void {
+  expect(node).toHaveProperty('nodeType');
+  expect(node).toHaveProperty('displayName');
+  expect(node).toHaveProperty('properties');
+  expect(Array.isArray(node.properties)).toBe(true);
+}
+```
+
+## Unit Testing
+
+Our unit tests focus on testing individual components in isolation with mocked dependencies:
+
+### Service Layer Tests
+
+The bulk of our unit tests (400+ tests) are in the services layer:
+
+```typescript
+// tests/unit/services/workflow-validator-comprehensive.test.ts
+describe('WorkflowValidator Comprehensive Tests', () => {
+  it('should validate complex workflow with AI nodes', () => {
+    const workflow = {
+      nodes: [
+        {
+          id: 'ai_agent',
+          type: '@n8n/n8n-nodes-langchain.agent',
+          parameters: { prompt: 'Analyze data' }
+        }
+      ],
+      connections: {}
+    };
+    
+    const result = validator.validateWorkflow(workflow);
+    expect(result.valid).toBe(true);
+  });
+});
+```
+
+### Parser Tests
+
+Testing the node parsing logic:
+
+```typescript
+// tests/unit/parsers/property-extractor.test.ts
+describe('PropertyExtractor', () => {
+  it('should extract nested properties correctly', () => {
+    const node = {
+      properties: [
+        {
+          displayName: 'Options',
+          name: 'options',
+          type: 'collection',
+          options: [
+            { name: 'timeout', type: 'number' }
+          ]
+        }
+      ]
+    };
+    
+    const extracted = extractor.extractProperties(node);
+    expect(extracted).toHaveProperty('options.timeout');
+  });
+});
+```
+
+### Mock Testing
+
+Testing our mock implementations:
+
+```typescript
+// tests/unit/__mocks__/n8n-nodes-base.test.ts
+describe('n8n-nodes-base mock', () => {
+  it('should provide mocked node definitions', () => {
+    const httpNode = mockNodes['n8n-nodes-base.httpRequest'];
+    expect(httpNode).toBeDefined();
+    expect(httpNode.description.displayName).toBe('HTTP Request');
+  });
+});
+```
+
+## Integration Testing
+
+Our integration tests verify the complete system behavior:
+
+### MCP Protocol Testing
+
+```typescript
+// tests/integration/mcp-protocol/tool-invocation.test.ts
+describe('MCP Tool Invocation', () => {
+  let mcpServer: TestableN8NMCPServer;
+  let client: Client;
+
+  beforeEach(async () => {
+    mcpServer = new TestableN8NMCPServer();
+    await mcpServer.initialize();
+    
+    const [serverTransport, clientTransport] = InMemoryTransport.createLinkedPair();
+    await mcpServer.connectToTransport(serverTransport);
+    
+    client = new Client({ name: 'test-client', version: '1.0.0' }, {});
+    await client.connect(clientTransport);
+  });
+
+  it('should list nodes with filtering', async () => {
+    const response = await client.callTool({ 
+      name: 'list_nodes', 
+      arguments: { category: 'trigger', limit: 10 } 
+    });
+    
+    expectValidMCPResponse(response);
+    const result = JSON.parse(response.content[0].text);
+    expect(result.nodes).toHaveLength(10);
+    expect(result.nodes.every(n => n.category === 'trigger')).toBe(true);
+  });
+});
+```
+
+### Database Integration Testing
+
+```typescript
+// tests/integration/database/fts5-search.test.ts
+describe('FTS5 Search Integration', () => {
+  it('should perform fuzzy search', async () => {
+    const results = await nodeRepo.searchNodes('HTT', 'FUZZY');
+    
+    expect(results.some(n => n.nodeType.includes('httpRequest'))).toBe(true);
+    expect(results.some(n => n.displayName.includes('HTTP'))).toBe(true);
+  });
+
+  it('should handle complex boolean queries', async () => {
+    const results = await nodeRepo.searchNodes('webhook OR http', 'OR');
+    
+    expect(results.length).toBeGreaterThan(0);
+    expect(results.some(n => 
+      n.description?.includes('webhook') || 
+      n.description?.includes('http')
+    )).toBe(true);
+  });
+});
+```

+```typescript
+// tests/benchmarks/database-queries.bench.ts
+import { bench, describe } from 'vitest';
+
+describe('Database Query Performance', () => {
+  bench('search nodes by category', async () => {
+    await nodeRepo.getNodesByCategory('trigger');
+  });
+
+  bench('FTS5 search performance', async () => {
+    await nodeRepo.searchNodes('webhook http request', 'AND');
+  });
+});
+```
+
+## Environment Configuration
+
+Test environment is configured via `.env.test`:
+
+```bash
+# Test Environment Configuration
+NODE_ENV=test
+TEST_DB_PATH=:memory:
+TEST_PARALLEL=false
+TEST_MAX_WORKERS=4
+FEATURE_TEST_COVERAGE=true
+MSW_ENABLED=true
+```
+
+## Key Patterns and Lessons Learned
+
+### 1. Response Structure Consistency
+
+All MCP responses follow a specific structure that must be handled correctly:
+
+```typescript
+// Common pattern for handling MCP responses
+const response = await client.callTool({ name: 'list_nodes', arguments: {} });
+
+// MCP responses have content array with text objects
+expect(response.content).toBeDefined();
+expect(response.content[0].type).toBe('text');
+
+// Parse the actual data
+const data = JSON.parse(response.content[0].text);
+```
+
+### 2. MSW Integration Setup
+
+Proper MSW setup is crucial for integration tests:
+
+```typescript
+// tests/integration/setup/integration-setup.ts
+import { setupServer } from 'msw/node';
+import { handlers } from '@tests/mocks/n8n-api/handlers';
+
+// Create server but don't start it globally
+const server = setupServer(...handlers);
+
+beforeAll(async () => {
+  // Only start MSW for integration tests
+  if (process.env.MSW_ENABLED === 'true') {
+    server.listen({ onUnhandledRequest: 'bypass' });
+  }
+});
+
+afterAll(async () => {
+  server.close();
+});
+```
+
+### 3. Database Isolation for Parallel Tests
+
+Each test gets its own database to enable parallel execution:
+
+```typescript
+// tests/utils/database-utils.ts
+export function createTestDatabaseAdapter(
+  db?: Database.Database,
+  options: TestDatabaseOptions = {}
+): DatabaseAdapter {
+  const database = db || new Database(':memory:');
+  
+  // Enable FTS5 if needed
+  if (options.enableFTS5) {
+    database.exec('PRAGMA main.compile_options;');
+  }
+  
+  return new DatabaseAdapter(database);
+}
+```
+
+### 4. Environment-Aware Performance Thresholds
+
+CI environments are slower, so we adjust expectations:
+
+```typescript
+// Environment-aware thresholds
+const getThreshold = (local: number, ci: number) => 
+  process.env.CI ? ci : local;
+
+it('should respond quickly', async () => {
+  const start = performance.now();
+  await someOperation();
+  const duration = performance.now() - start;
+  
+  expect(duration).toBeLessThan(getThreshold(50, 200));
+});
+```
+
+## Best Practices
+
+### 1. Test Isolation
+- Each test creates its own database instance
+- Tests clean up after themselves
+- No shared state between tests
+
+### 2. Proper Cleanup Order
+```typescript
+afterEach(async () => {
+  // Close client first to ensure no pending requests
+  await client.close();
+  
+  // Give time for client to fully close
+  await new Promise(resolve => setTimeout(resolve, 50));
+  
+  // Then close server
+  await mcpServer.close();
+  
+  // Finally cleanup database
+  await testDb.cleanup();
+});
+```
+
+### 3. Handle Async Operations Carefully
+```typescript
+// Avoid race conditions in cleanup
+it('should handle disconnection', async () => {
+  // ... test code ...
+  
+  // Ensure operations complete before cleanup
+  await transport.close();
+  await new Promise(resolve => setTimeout(resolve, 100));
+});
+```
+
+### 4. Meaningful Test Organization
+- Group related tests using `describe` blocks
+- Use descriptive test names that explain the behavior
+- Follow AAA pattern: Arrange, Act, Assert
+- Keep tests focused on single behaviors
+
+## Debugging Tests
+
+### Running Specific Tests
+```bash
+# Run a single test file
+npm test tests/integration/mcp-protocol/tool-invocation.test.ts
+
+# Run tests matching a pattern
+npm test -- --grep "should list nodes"
+
+# Run with debugging output
+DEBUG=* npm test
+```
+
+### VSCode Integration
+```json
+// .vscode/launch.json
+{
+  "configurations": [
+    {
+      "type": "node",
+      "request": "launch",
+      "name": "Debug Tests",
+      "program": "${workspaceFolder}/node_modules/vitest/vitest.mjs",
+      "args": ["run", "${file}"],
+      "console": "integratedTerminal"
+    }
+  ]
+}
+```
+
+## Test Coverage
+
+While we don't enforce strict coverage thresholds yet, the infrastructure is in place:
+- Coverage reports generated in `lcov`, `html`, and `text` formats
+- Integration with Codecov for tracking coverage over time
+- Per-file coverage visible in VSCode with extensions
+
+## Future Improvements
+
+1. **E2E Testing**: Add Playwright for testing the full MCP server interaction
+2. **Load Testing**: Implement k6 or Artillery for stress testing
+3. **Contract Testing**: Add Pact for ensuring API compatibility
+4. **Visual Regression**: For any UI components that may be added
+5. **Mutation Testing**: Use Stryker to ensure test quality
+
+## Common Issues and Solutions
+
+### 1. Tests Hanging in CI
+
+**Problem**: Tests would hang indefinitely in CI due to `process.exit()` calls.
+
+**Solution**: Remove all `process.exit()` calls from test code and use proper cleanup:
+```typescript
+// Bad
+afterAll(() => {
+  process.exit(0); // This causes Vitest to hang
+});
+
+// Good
+afterAll(async () => {
+  await cleanup();
+  // Let Vitest handle process termination
+});
+```
+
+### 2. MCP Response Structure
+
+**Problem**: Tests expecting wrong response format from MCP tools.
+
+**Solution**: Always access responses through `content[0].text`:
+```typescript
+// Wrong
+const data = response[0].text;
+
+// Correct
+const data = JSON.parse(response.content[0].text);
+```
+
+### 3. Database Not Found Errors
+
+**Problem**: Tests failing with "node not found" when database is empty.
+
+**Solution**: Check for empty databases before assertions:
+```typescript
+const stats = await server.executeTool('get_database_statistics', {});
+if (stats.totalNodes > 0) {
+  expect(result.nodes.length).toBeGreaterThan(0);
+} else {
+  expect(result.nodes).toHaveLength(0);
+}
+```
+
+### 4. MSW Loading Globally
+
+**Problem**: MSW interfering with unit tests when loaded globally.
+
+**Solution**: Only load MSW in integration test setup:
+```typescript
+// vitest.config.integration.ts
+setupFiles: [
+  './tests/setup/global-setup.ts',
+  './tests/integration/setup/integration-setup.ts' // MSW only here
+]
+```

+{
+  "scripts": {
+    // Testing
+    "test": "vitest",
+    "test:ui": "vitest --ui",
+    "test:unit": "vitest run tests/unit",
+    "test:integration": "vitest run tests/integration",

+    "test:ci": "vitest run --reporter=junit --reporter=default",
+    "test:ci:coverage": "vitest run --coverage --reporter=junit --reporter=default"
+  }
+}
+```
+
+### 1.3 Migrate Existing Tests
+
+```typescript
+// Before (Jest)
+import { describe, test, expect } from '@jest/globals';
+
+// After (Vitest)
+import { describe, it, expect, vi } from 'vitest';
+
+// Update mock syntax
+// Jest: jest.mock('module')
+// Vitest: vi.mock('module')
+
+// Update timer mocks
+// Jest: jest.useFakeTimers()
+// Vitest: vi.useFakeTimers()
+```
+
+### 1.4 Create Test Database Setup
+
+```typescript
+// tests/setup/test-database.ts
+import Database from 'better-sqlite3';
+import { readFileSync } from 'fs';
+import { join } from 'path';
+
+export class TestDatabase {
+  private db: Database.Database;
+  
+  constructor() {
+    this.db = new Database(':memory:');
+    this.initialize();
+  }
+  
+  private initialize() {
+    const schema = readFileSync(
+      join(__dirname, '../../src/database/schema.sql'),
+      'utf8'
+    );
+    this.db.exec(schema);
+  }
+  
+  seedNodes(nodes: any[]) {
+    const stmt = this.db.prepare(`
+      INSERT INTO nodes (type, displayName, name, group, version, description, properties)
+      VALUES (?, ?, ?, ?, ?, ?, ?)
+    `);
+    
+    const insertMany = this.db.transaction((nodes) => {
+      for (const node of nodes) {
+        stmt.run(
+          node.type,
+          node.displayName,
+          node.name,
+          node.group,
+          node.version,
+          node.description,
+          JSON.stringify(node.properties)
+        );
+      }
+    });
+    
+    insertMany(nodes);
+  }
+  
+  close() {
+    this.db.close();
+  }
+  
+  getDb() {
+    return this.db;
+  }
+}
+```
+
+## Phase 2: Core Unit Tests (Week 3-4)
+
+### 2.1 Test Organization Template
+
+```typescript
+// tests/unit/services/[service-name].test.ts
+import { describe, it, expect, beforeEach, afterEach, vi } from 'vitest';
+import { ServiceName } from '@/services/service-name';
+
+describe('ServiceName', () => {
+  let service: ServiceName;
+  let mockDependency: any;
+  
+  beforeEach(() => {
+    // Setup mocks
+    mockDependency = {
+      method: vi.fn()
+    };
+    
+    // Create service instance
+    service = new ServiceName(mockDependency);
+  });
+  
+  afterEach(() => {
+    vi.clearAllMocks();
+  });
+  
+  describe('methodName', () => {
+    it('should handle happy path', async () => {
+      // Arrange
+      const input = { /* test data */ };
+      mockDependency.method.mockResolvedValue({ /* mock response */ });
+      
+      // Act
+      const result = await service.methodName(input);
+      
+      // Assert
+      expect(result).toEqual(/* expected output */);
+      expect(mockDependency.method).toHaveBeenCalledWith(/* expected args */);
+    });
+    
+    it('should handle errors gracefully', async () => {
+      // Arrange
+      mockDependency.method.mockRejectedValue(new Error('Test error'));
+      
+      // Act & Assert
+      await expect(service.methodName({})).rejects.toThrow('Expected error message');
+    });
+  });
+});
+```
+
+### 2.2 Mock Strategies by Layer
+
+#### Database Layer
+```typescript
+// tests/unit/database/node-repository.test.ts
+import { vi } from 'vitest';
+
+vi.mock('better-sqlite3', () => ({
+  default: vi.fn(() => ({
+    prepare: vi.fn(() => ({
+      all: vi.fn(() => mockData),
+      get: vi.fn((id) => mockData.find(d => d.id === id)),
+      run: vi.fn(() => ({ changes: 1 }))
+    })),
+    exec: vi.fn(),
+    close: vi.fn()
+  }))
+}));
+```
+
+#### External APIs
+```typescript
+// tests/unit/services/__mocks__/axios.ts
+export default {
+  create: vi.fn(() => ({
+    get: vi.fn(() => Promise.resolve({ data: {} })),
+    post: vi.fn(() => Promise.resolve({ data: { id: '123' } })),
+    put: vi.fn(() => Promise.resolve({ data: {} })),
+    delete: vi.fn(() => Promise.resolve({ data: {} }))
+  }))
+};
+```
+
+#### File System
+```typescript
+// Use memfs for file system mocking
+import { vol } from 'memfs';
+
+vi.mock('fs', () => vol);
+
+beforeEach(() => {
+  vol.reset();
+  vol.fromJSON({
+    '/test/file.json': JSON.stringify({ test: 'data' })
+  });
+});
+```
+
+### 2.3 Critical Path Tests
+
+```typescript
+// Priority 1: Node Loading and Parsing
+// tests/unit/loaders/node-loader.test.ts
+
+// Priority 2: Configuration Validation
+// tests/unit/services/config-validator.test.ts

+// Priority 5: Workflow Validation
+// tests/unit/services/workflow-validator.test.ts
+```
+
+## Phase 3: Integration Tests (Week 5-6)
+
+### 3.1 Test Container Setup
+
+```typescript
+// tests/setup/test-containers.ts
+import { GenericContainer, StartedTestContainer } from 'testcontainers';
+
+export class N8nTestContainer {
+  private container: StartedTestContainer;
+  
+  async start() {
+    this.container = await new GenericContainer('n8nio/n8n:latest')
+      .withExposedPorts(5678)
+      .withEnv('N8N_BASIC_AUTH_ACTIVE', 'false')
+      .withEnv('N8N_ENCRYPTION_KEY', 'test-key')
+      .start();
+    
+    return {
+      url: `http://localhost:${this.container.getMappedPort(5678)}`,
+      stop: () => this.container.stop()
+    };
+  }
+}
+```
+
+### 3.2 Integration Test Pattern
+
+```typescript
+// tests/integration/n8n-api/workflow-crud.test.ts
+import { N8nTestContainer } from '@tests/setup/test-containers';
+import { N8nAPIClient } from '@/services/n8n-api-client';
+
+describe('n8n API Integration', () => {
+  let container: any;
+  let apiClient: N8nAPIClient;
+  
+  beforeAll(async () => {
+    container = await new N8nTestContainer().start();
+    apiClient = new N8nAPIClient(container.url);
+  }, 30000);
+  
+  afterAll(async () => {
+    await container.stop();
+  });
+  
+  it('should create and retrieve workflow', async () => {
+    // Create workflow
+    const workflow = createTestWorkflow();
+    const created = await apiClient.createWorkflow(workflow);
+    
+    expect(created.id).toBeDefined();
+    
+    // Retrieve workflow
+    const retrieved = await apiClient.getWorkflow(created.id);
+    expect(retrieved.name).toBe(workflow.name);
+  });
+});
+```
+
+## Phase 4: E2E & Performance (Week 7-8)
+
+### 4.1 E2E Test Setup
+
+```typescript
+// tests/e2e/workflows/complete-workflow.test.ts
+import { MCPClient } from '@tests/utils/mcp-client';
+import { N8nTestContainer } from '@tests/setup/test-containers';
+
+describe('Complete Workflow E2E', () => {
+  let mcpServer: any;
+  let n8nContainer: any;
+  let mcpClient: MCPClient;
+  
+  beforeAll(async () => {
+    // Start n8n
+    n8nContainer = await new N8nTestContainer().start();
+    
+    // Start MCP server
+    mcpServer = await startMCPServer({
+      n8nUrl: n8nContainer.url
+    });
+    
+    // Create MCP client
+    mcpClient = new MCPClient(mcpServer.url);
+  }, 60000);
+  
+  it('should execute complete workflow creation flow', async () => {
+    // 1. Search for nodes
+    const searchResult = await mcpClient.call('search_nodes', {
+      query: 'webhook http slack'
+    });
+    
+    // 2. Get node details
+    const webhookInfo = await mcpClient.call('get_node_info', {
+      nodeType: 'nodes-base.webhook'
+    });
+    
+    // 3. Create workflow
+    const workflow = new WorkflowBuilder('E2E Test')
+      .addWebhookNode()
+      .addHttpRequestNode()
+      .addSlackNode()
+      .connectSequentially()
+      .build();
+    
+    // 4. Validate workflow
+    const validation = await mcpClient.call('validate_workflow', {
+      workflow
+    });
+    
+    expect(validation.isValid).toBe(true);
+    
+    // 5. Deploy to n8n
+    const deployed = await mcpClient.call('n8n_create_workflow', {
+      ...workflow
+    });
+    
+    expect(deployed.id).toBeDefined();
+    expect(deployed.active).toBe(false);
+  });
+});
+```
+
+### 4.2 Performance Benchmarks
+
+```typescript
+// vitest.benchmark.config.ts
+export default {
+  test: {
+    benchmark: {
+      // Output benchmark results
+      outputFile: './benchmark-results.json',
+      
+      // Compare with baseline
+      compare: './benchmark-baseline.json',
+      
+      // Fail if performance degrades by more than 10%
+      threshold: {
+        p95: 1.1, // 110% of baseline
+        p99: 1.2  // 120% of baseline
+      }
+    }
+  }
+};
+```
+
+## Testing Best Practices
+
+### 1. Test Naming Convention
+```typescript
+// Format: should [expected behavior] when [condition]
+it('should return user data when valid ID is provided')
+it('should throw ValidationError when email is invalid')
+it('should retry 3 times when network fails')
+```
+
+### 2. Test Data Builders
+```typescript
+// Use builders for complex test data
+const user = new UserBuilder()
+  .withEmail('test@example.com')
+  .withRole('admin')
+  .build();
+```
+
+### 3. Custom Matchers
+```typescript
+// tests/utils/matchers.ts
+export const toBeValidNode = (received: any) => {
+  const pass = 
+    received.type &&
+    received.displayName &&
+    received.properties &&
+    Array.isArray(received.properties);
+  
+  return {
+    pass,
+    message: () => `expected ${received} to be a valid node`
+  };
+};
+
+// Usage
+expect(node).toBeValidNode();
+```
+
+### 4. Snapshot Testing
+```typescript
+// For complex structures
+it('should generate correct node schema', () => {
+  const schema = generateNodeSchema(node);
+  expect(schema).toMatchSnapshot();
+});
+```
+
+### 5. Test Isolation
+```typescript
+// Always clean up after tests
+afterEach(async () => {
+  await cleanup();
+  vi.clearAllMocks();
+  vi.restoreAllMocks();
+});
+```
+

+# Token Efficiency Improvements Summary
+
+## Overview
+Made all MCP tool descriptions concise and token-efficient while preserving essential information.
+
+## Key Improvements
+
+### Before vs After Examples
+
+1. **search_nodes**
+   - Before: ~350 chars with verbose explanation
+   - After: 165 chars
+   - `Search nodes by keywords. Modes: OR (any word), AND (all words), FUZZY (typos OK). Primary nodes ranked first. Examples: "webhook"→Webhook, "http call"→HTTP Request.`
+
+2. **get_node_info**
+   - Before: ~450 chars with warnings about size
+   - After: 174 chars
+   - `Get FULL node schema (100KB+). TIP: Use get_node_essentials first! Returns all properties/operations/credentials. Prefix required: "nodes-base.httpRequest" not "httpRequest".`
+
+3. **validate_node_minimal**
+   - Before: ~350 chars explaining what it doesn't do
+   - After: 102 chars
+   - `Fast check for missing required fields only. No warnings/suggestions. Returns: list of missing fields.`
+
+4. **get_property_dependencies**
+   - Before: ~400 chars with full example
+   - After: 131 chars
+   - `Shows property dependencies and visibility rules. Example: sendBody=true reveals body fields. Test visibility with optional config.`
+
+## Statistics
+
+### Documentation Tools (22 tools)
+- Average description length: **129 characters**
+- Total characters: 2,836
+- Tools over 200 chars: 1 (list_nodes at 204)
+
+### Management Tools (17 tools)
+- Average description length: **93 characters**
+- Total characters: 1,578
+- Tools over 200 chars: 1 (n8n_update_partial_workflow at 284)
+
+## Strategy Used
+
+1. **Remove redundancy**: Eliminated repeated information available in parameter descriptions
+2. **Use abbreviations**: "vs" instead of "versus", "&" instead of "and" where appropriate
+3. **Compact examples**: `"webhook"→Webhook` instead of verbose explanations
+4. **Direct language**: "Fast check" instead of "Quick validation that only checks"
+5. **Move details to documentation**: Complex tools reference `tools_documentation()` for full details
+6. **Essential info only**: Focus on what the tool does, not how it works internally
+
+## Special Cases
+
+### n8n_update_partial_workflow
+This tool's description is necessarily longer (284 chars) because:
+- Lists all 13 operation types
+- Critical for users to know available operations
+- Directs to full documentation for details
+
+### Complex Documentation Preserved
+For tools like `n8n_update_partial_workflow`, detailed documentation was moved to `tools-documentation.ts` rather than deleted, ensuring users can still access comprehensive information when needed.
+
+## Impact
+- **Token savings**: ~65-70% reduction in description tokens
+- **Faster AI responses**: Less context used for tool descriptions
+- **Better UX**: Clearer, more scannable tool list
+- **Maintained functionality**: All essential information preserved

-# Transactional Updates Implementation Summary
-
-## Overview
-
-We successfully implemented a simple transactional update system for the `n8n_update_partial_workflow` tool that allows AI agents to add nodes and connect them in a single request, regardless of operation order.
-
-## Key Changes
-
-### 1. WorkflowDiffEngine (`src/services/workflow-diff-engine.ts`)
-
-- Added **5 operation limit** to keep complexity manageable
-- Implemented **two-pass processing**:
-  - Pass 1: Node operations (add, remove, update, move, enable, disable)
-  - Pass 2: Other operations (connections, settings, metadata)
-- Operations are always applied to working copy for proper validation
-
-### 2. Benefits
-
-- **Order Independence**: AI agents can write operations in any logical order
-- **Atomic Updates**: All operations succeed or all fail
-- **Simple Implementation**: ~50 lines of code change
-- **Backward Compatible**: Existing usage still works
-
-### 3. Example Usage
-
-```json
-{
-  "id": "workflow-id",
-  "operations": [
-    // Connections first (would fail before)
-    { "type": "addConnection", "source": "Start", "target": "Process" },
-    { "type": "addConnection", "source": "Process", "target": "End" },
-    
-    // Nodes added later (processed first internally)
-    { "type": "addNode", "node": { "name": "Process", ... }},
-    { "type": "addNode", "node": { "name": "End", ... }}
-  ]
-}
-```
-
-## Testing
-
-Created comprehensive test suite (`src/scripts/test-transactional-diff.ts`) that validates:
-- Mixed operations with connections before nodes
-- Operation limit enforcement (max 5)
-- Validate-only mode
-- Complex mixed operations
-
-All tests pass successfully!
-
-## Documentation Updates
-
-1. **CLAUDE.md** - Added transactional updates to v2.7.0 release notes
-2. **workflow-diff-examples.md** - Added new section explaining transactional updates
-3. **Tool description** - Updated to highlight order independence
-4. **transactional-updates-example.md** - Before/after comparison
-
-## Why This Approach?
-
-1. **Simplicity**: No complex dependency graphs or topological sorting
-2. **Predictability**: Clear two-pass rule is easy to understand
-3. **Reliability**: 5 operation limit prevents edge cases
-4. **Performance**: Minimal overhead, same validation logic
-
-## Future Enhancements (Not Implemented)
-
-If needed in the future, we could add:
-- Automatic operation reordering based on dependencies
-- Larger operation limits with smarter batching
-- Dependency hints in error messages
-
-But the current simple approach covers 90%+ of use cases effectively!
