**`discover_nodes`** - Analyze workflows to discover node types - Scans all workflows via n8n API - Extracts node types, parameters, credentials - Tracks usage statistics and popularity - Infers parameter types from real data - Persists to SQLite (~/.n8n-mcp/node_discovery.db) - **`get_node_schema`** - Get detailed schema for discovered nodes - Parameter names and inferred types - Credential requirements - Usage count across workflows - Real-world configuration examples - **`search_nodes`** - Search nodes by keyword - Keyword matching in node type and name - Category classification (trigger, data_source, transform, notification, http, logic, utility) - Icon-based visual categorization (⚡📊🔄📬🌐🔀🔧) - Sorted by popularity - **`recommend_nodes_for_task`** - AI-powered node recommendations - Natural language task descriptions - Advanced scoring algorithm (exact: 5pts, synonym: 2.5pts, parameter: +1pt) - Bidirectional synonym matching (40+ terms) - Popularity boost (max 3pts) - Detailed reason generation #### Advanced Features **Synonym Matching (Bidirectional)** - `slack` ↔ telegram, discord, mattermost, matrix, chat, message - `excel` ↔ sheets, spreadsheet, airtable, table - `database` ↔ postgres, mysql, mongodb, sql, db - `send` ↔ post, push, publish, transmit - `read` ↔ get, fetch, retrieve, load - `cloud` ↔ drive, dropbox, s3, storage - 40+ comprehensive synonym mappings **Parameter-Based Scoring** - Bonus points for nodes with relevant parameters - "email" task → finds nodes with "email" parameter - Helps distinguish similar nodes by capabilities **Category Tagging** - 7 categories: trigger, data_source, transform, notification, http, logic, utility - Auto-categorization based on node_type keywords - Persisted in database for consistency - Visual icons in search results **Stopword Filtering** - Filters 23 common English words (and, to, from, the, etc.) - Filters words < 3 characters - Improves matching relevance #### Architecture **Database Persistence** - Location: `~/.n8n-mcp/node_discovery.db` - SQLite with discovered_nodes table - Stores node types, parameters, types, credentials, usage counts - Auto-loads on server start - Survives restarts **Performance** - Discovery: 10 workflows (~2s), 100 workflows (~15s) - Recommendations: < 200ms for 100 nodes - In-memory caching for fast queries ### 🐛 Fixed **Synonym Matching Fixes** - Fixed synonyms not appearing in recommendation reasons - Fixed bidirectional synonym mapping -

Changed `global` to `nonlocal` for proper nested function scope ### 🔄 Improved **Scoring Algorithm** - Increased exact keyword match from +2 to +5 points - Added synonym match at +2.5 points (0.5x weight) - Reduced popularity boost from +5 to +3 max - Popularity only added if keywords match (prevents irrelevant popular nodes) - Parameter matching adds +1 point bonus **Recommendation Reasons** - Shows exact keyword matches: "Matches: send, message" - Shows synonym matches: "Similar: slack" - Shows popularity: "highly popular" or "commonly used" - Clear explanation of why node was recommended ### 📚 Documentation **New Files** - `docs/NODE_DISCOVERY.md` -

**Root Cause**: Duplicate local import caused Python to treat WORKFLOW_TEMPLATES as local variable - **Fix**: Removed redundant import since WORKFLOW_TEMPLATES is already imported at module level - **Commit**: `bb2b6fc` #### Fixed UnboundLocalError in get_template_details - **Issue**: Same UnboundLocalError when retrieving template details - **Root Cause**: Direct access to WORKFLOW_TEMPLATES without proper fallback logic - **Fix**: Refactored to use template registry with backward compatibility fallback - **Commit**: `e85f877` #### Enhanced get_template_details Output - **Added**: Source, complexity, node count, purpose, external systems - **Added**: Quality indicators (error handling, documentation) - **Added**: Trust metrics (success rate, usage count) - **Backward Compatible**: Old templates still work via fallback ### 📝 Technical Details - Python scope issue: Local imports later in function make variables local throughout entire scope - Solution: Import at module level, avoid local imports of module-level variables - All template tools now verified working correctly ### ✅ Testing - ✅ `generate_workflow_template` - Works correctly - ✅ `get_template_details` - Works with enhanced metadata - ✅ Backward compatibility - Old templates still accessible - ✅ All other template tools - Verified safe --- ## [1.18.0] - 2025-12-17 ### 🎯 Added - Drift Detection System **Major Feature**: Proactive workflow quality monitoring that detects degradation before it becomes critical. #### Drift Detection Tools -
