2cb264fd56 fix: implement Single-Session architecture to resolve MCP stream errors
- Add ConsoleManager to prevent console output interference with StreamableHTTPServerTransport
- Implement SingleSessionHTTPServer with persistent session reuse
- Create N8NMCPEngine for clean service integration
- Add automatic session expiry after 30 minutes of inactivity
- Update logger to be HTTP-aware during active requests
- Maintain backward compatibility with existing deployments

This fixes the "stream is not readable" error by implementing the Hybrid
Single-Session architecture as documented in MCP_ERROR_FIX_PLAN.md

3ab8fbd60b feat: implement Docker image optimization - reduces size from 2.6GB to ~200MB
- Add optimized database schema with embedded source code storage
- Create optimized rebuild script that extracts source at build time
- Implement optimized MCP server reading from pre-built database
- Add Dockerfile.optimized with multi-stage build process
- Create comprehensive documentation and testing scripts
- Demonstrate 92% size reduction by removing runtime n8n dependencies

The optimization works by:
1. Building complete database at Docker build time
2. Extracting all node source code into the database
3. Creating minimal runtime image without n8n packages
4. Serving everything from pre-built SQLite database

This makes n8n-MCP suitable for resource-constrained production deployments.

887e98ca0b Add production deployment scripts and quickstart guide
- Add deploy-to-vm.sh script for easy VM deployment
- Add systemd service file template
- Add Nginx configuration with SSL and rate limiting
- Add DEPLOYMENT_QUICKSTART.md for n8ndocumentation.aiservices.pl
- Update REMOTE_DEPLOYMENT.md to reference quickstart

The deployment process is now streamlined:
1. Copy .env.example to .env
2. Configure for production (domain, auth token)
3. Run ./scripts/deploy-to-vm.sh

Tested locally with production configuration - all endpoints
working correctly with authentication.

1dd6b8e55f Clean up legacy documentation and scripts
- Remove all references to workflow execution/management features
- Delete legacy scripts for bidirectional n8n integration
- Update documentation to focus on node documentation serving only
- Remove old docker-compose files for workflow management
- Add simplified docker-compose.yml for documentation server
- Update CHANGELOG.md to reflect v2.0.0 and v2.1.0 changes
- Update Dockerfile to use v2 paths and database

The project is now clearly focused on serving n8n node documentation
to AI assistants, with no workflow execution capabilities.

078b67ff35 Implement SQLite database with full-text search for n8n node documentation
Major features implemented:
- SQLite storage service with FTS5 for fast node search
- Database rebuild mechanism for bulk node extraction
- MCP tools: search_nodes, extract_all_nodes, get_node_statistics
- Production Docker deployment with persistent storage
- Management scripts for database operations
- Comprehensive test suite for all functionality

Database capabilities:
- Stores node source code and metadata
- Full-text search by node name or content
- No versioning (stores latest only as per requirements)
- Supports complete database rebuilds
- ~4.5MB database with 500+ nodes indexed

Production features:
- Automated deployment script
- Docker Compose production configuration
- Database initialization on first run
- Volume persistence for data
- Management utilities for operations

Documentation:
- Updated README with complete instructions
- Production deployment guide
- Clear troubleshooting section
- API reference for all new tools

04627616d4 Add AI Agent node source code extraction capability
This commit implements the ability to extract n8n node source code through MCP:

Features:
- New MCP tools: get_node_source_code and list_available_nodes
- NodeSourceExtractor utility for file system access to n8n nodes
- Support for extracting any n8n node including AI Agent from @n8n/n8n-nodes-langchain
- Resource endpoint for accessing node source: nodes://source/{nodeType}

Testing:
- Docker test environment with mounted n8n node_modules
- Multiple test scripts for different scenarios
- Comprehensive test documentation
- Standalone MCP client test demonstrating full extraction flow

The implementation successfully demonstrates:
1. MCP server can access n8n's installed nodes
2. Source code can be extracted and returned to MCP clients
3. Full metadata including package info and file locations
4. Support for credential code extraction when available
