a0f09fba28 fix: resolve HTTP server URL handling and security issues (#41, #42)
- Add intelligent URL detection supporting BASE_URL, PUBLIC_URL, and proxy headers
- Fix hardcoded localhost URLs in server console output
- Add hostname validation to prevent host header injection attacks
- Restrict URL schemes to http/https only (block javascript:, file://, etc.)
- Remove sensitive environment data from API responses
- Add GET endpoints (/, /mcp) for better API discovery
- Fix version inconsistency between server implementations
- Update HTTP bridge to use HOST/PORT environment variables
- Add comprehensive test scripts for URL configuration and security

This resolves issues #41 and #42 by making the HTTP server properly handle
deployment behind reverse proxies and adds critical security validations.

4c217088f5 fix: resolve partial update validation/execution discrepancy (issue #45)
- Remove default settings logic from cleanWorkflowForUpdate that was causing
  "settings must NOT have additional properties" error
- The function now only removes read-only fields without adding any properties
- Add comprehensive test coverage in test-issue-45-fix.ts
- Add documentation explaining the difference between create and update functions
- Bump version to 2.7.14

This fixes the issue where n8n_update_partial_workflow would pass validation
but fail during execution when workflows didn't have settings defined.

e8f6b684f0 fix: make FTS5 optional for template search (fixes Claude Desktop compatibility)
- Added runtime FTS5 detection in database adapters
- Removed FTS5 from required schema to prevent "no such module" errors
- FTS5 tables/triggers created conditionally only if supported
- Template search automatically falls back to LIKE when FTS5 unavailable
- Works in ALL SQLite environments (Claude Desktop, restricted envs, etc.)

This ensures search_templates() works correctly regardless of SQLite build,
while still providing optimal performance when FTS5 is available.

d8e84307e4 feat: optimize MCP tool descriptions for 65-70% token reduction
- Reduced average description length from 250-450 to 93-129 chars
- Documentation tools now average 129 chars per description
- Management tools average just 93 chars per description
- Moved detailed documentation to tools_documentation() system
- Only 2 tools exceed 200 chars (necessarily verbose)

Also includes search_nodes improvements:
- Fixed primary node ranking (webhook, HTTP Request now appear first)
- Fixed FUZZY mode threshold for better typo tolerance
- Removed unnecessary searchInfo messages
- Fixed HTTP node type case sensitivity issue

This significantly improves AI agent performance by reducing context usage
while preserving all essential information.

99e74cf22a fix: correct misleading Code node documentation based on real-world testing
Critical fixes based on Claude Desktop feedback:

1. Fixed crypto documentation: require('crypto') IS available despite editor warnings
   - Added clear examples of crypto usage
   - Updated validation to guide correct require() usage

2. Clarified $helpers vs standalone functions
   - $getWorkflowStaticData() is standalone, NOT $helpers.getWorkflowStaticData()
   - Added validation to catch incorrect usage (prevents '$helpers is not defined' errors)
   - Enhanced examples showing proper $helpers availability checks

3. Fixed JMESPath numeric literal documentation
   - n8n requires backticks around numbers in filters: [?age >= `18`]
   - Added multiple examples and validation to detect missing backticks
   - Prevents 'JMESPath syntax error' that Claude Desktop encountered

4. Fixed webhook data access gotcha
   - Webhook payload is at items[0].json.body, NOT items[0].json
   - Added dedicated 'Webhook Data Access' section with clear examples
   - Created process_webhook_data task template
   - Added validation to detect incorrect webhook data access patterns

All fixes based on production workflows TaNqYoZNNeHC4Hne and JZ9urD7PNClDZ1bm

eab3cc858e fix: comprehensive error handling and node-level properties validation (fixes #26)
Root cause: AI agents were placing error handling properties inside `parameters` instead of at node level

Major changes:
- Enhanced workflow validator to check for ALL node-level properties (expanded from 6 to 11)
- Added validation for onError property values and deprecation warnings for continueOnFail
- Updated all examples to use modern error handling (onError instead of continueOnFail)
- Added comprehensive node-level properties documentation in tools_documentation
- Enhanced MCP tool documentation for n8n_create_workflow and n8n_update_partial_workflow
- Added test script demonstrating correct node-level property usage

Node-level properties now validated:
- credentials, disabled, notes, notesInFlow, executeOnce
- onError, retryOnFail, maxTries, waitBetweenTries, alwaysOutputData
- continueOnFail (deprecated)

Validation improvements:
- Detects misplaced properties and provides clear fix examples
- Shows complete node structure when properties are incorrectly placed
- Type validation for all node-level boolean and string properties
- Smart error messages with correct placement guidance

87f0cfc4dc feat: enhanced authentication logging for better debugging (fixes #22, #16)
- Added specific error reasons for auth failures: no_auth_header, invalid_auth_format, invalid_token
- Fixed AUTH_TOKEN_FILE support in Docker production stacks (issue #16)
- Added AUTH_TOKEN_FILE support to single-session HTTP server for consistency
- Enhanced security by removing token lengths from logs
- Added token trimming and empty token validation
- Updated Docker entrypoint to properly support AUTH_TOKEN_FILE
- Bumped version to 2.7.10

This improves debugging for mcp-remote authentication issues and enables
proper Docker secrets usage in production environments.

1f12c4b690 feat: add npx support for zero-installation usage (closes #15)
- Add bin configuration to package.json for npx execution
- Implement smart database path resolution for npx/global/local installs
- Create dedicated npm publish script using runtime-only dependencies
- Add .npmignore to control published package contents
- Update README with npx as primary installation method
- Add n8n version badge to README
- Sync version between package.json and package.runtime.json
- Update CHANGELOG for v2.7.8 release

This allows users to run 'npx n8n-mcp' without installing the package,
reducing friction and making it easier to get started with n8n-MCP.
