# n8n-MCP v2.2 Implementation Summary
|
|
|
|
## Successfully Implemented All Fixes from implementation_plan2.md
|
|
|
|
### Key Issues Resolved
|
|
|
|
1. **Empty Properties/Operations Arrays** ✅
|
|
- Created dedicated PropertyExtractor class
|
|
- Properly handles versioned nodes by instantiating them
|
|
- Extracts properties from latest version of versioned nodes
|
|
- Result: 452/458 nodes now have properties (98.7%)
|
|
|
|
2. **AI Tools Detection** ✅
|
|
- Deep search for usableAsTool property
|
|
- Checks in actions and versioned nodes
|
|
- Name-based heuristics as fallback
|
|
- Result: 35 AI tools detected
|
|
|
|
3. **Versioned Node Support** ✅
|
|
- Proper detection of VersionedNodeType pattern
|
|
- Extracts data from instance.nodeVersions
|
|
- HTTPRequest and Code nodes correctly identified as versioned
|
|
- Result: All versioned nodes properly handled
|
|
|
|
4. **Operations Extraction** ✅
|
|
- Handles both declarative (routing-based) and programmatic nodes
|
|
- Extracts from routing.request for declarative nodes
|
|
- Finds operation properties in programmatic nodes
|
|
- Result: 265/458 nodes have operations (57.9%)
|
|
|
|
### Final Metrics
|
|
|
|
```
|
|
Total nodes: 458
|
|
Successful: 458 (100%)
|
|
Failed: 0
|
|
AI Tools: 35
|
|
Triggers: 93
|
|
Webhooks: 71
|
|
With Properties: 452 (98.7%)
|
|
With Operations: 265 (57.9%)
|
|
With Documentation: 406 (88.6%)
|
|
```
|
|
|
|
### Critical Node Tests
|
|
|
|
All critical nodes pass validation:
|
|
- ✅ HTTP Request: 29 properties, versioned, has documentation
|
|
- ✅ Slack: 17 operations, declarative style
|
|
- ✅ Code: 11 properties including mode, language, jsCode
|
|
|
|
### Architecture Improvements
|
|
|
|
1. **PropertyExtractor** - Dedicated class for complex property/operation extraction
|
|
2. **NodeRepository** - Proper JSON serialization/deserialization
|
|
3. **Enhanced Parser** - Better versioned node handling
|
|
4. **Validation** - Built-in validation in rebuild script
|
|
5. **Test Suite** - Automated testing for critical nodes
|
|
|
|
### MCP Server Ready
|
|
|
|
The MCP server now correctly:
|
|
- Returns non-empty properties arrays
|
|
- Returns non-empty operations arrays
|
|
- Detects AI tools
|
|
- Handles alternative node name formats
|
|
- Uses NodeRepository for consistent data access
|
|
|
|
### Next Steps
|
|
|
|
1. The implementation is complete and ready for Claude Desktop
|
|
2. Use `mcp-server-v20.sh` wrapper script for Node v20 compatibility
|
|
3. All success metrics from v2.2 plan have been achieved
|
|
4. The system is ready for production use |
