3d7fdeba02 feat: Complete overhaul to enhanced documentation-only MCP server
- Removed all workflow execution capabilities per user requirements
- Implemented enhanced documentation extraction with operations and API mappings
- Fixed credential code extraction for all nodes
- Fixed package info extraction (name and version)
- Enhanced operations parser to handle n8n markdown format
- Fixed documentation search to prioritize app nodes over trigger nodes
- Comprehensive test coverage for Slack node extraction
- All node information now includes:
  - Complete operations list (42 for Slack)
  - API method mappings with documentation URLs
  - Source code and credential definitions
  - Package metadata
  - Related resources and templates

- get_node_info: Get complete node information
- search_nodes: Full-text search across nodes
- get_node_example: Get usage examples
- get_node_source_code: Get source code only
- get_node_documentation: Get documentation only
- rebuild_database: Rebuild entire database
- get_database_statistics: Database stats

Database schema includes:
- Node source code and metadata
- Official documentation from n8n-docs
- Generated usage examples
- Full-text search capabilities
- Category and type filtering

Updated README with:

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
