MCP Ollama Consult Server

# Phase 2 Progress - Handler Refactoring ## Status: 🟡 IN PROGRESS ## Completed ✅ - BaseHandler abstraction with validation & error handling - Handler directory structure created - 3/3 BaseHandler tests passing ## Analysis Results 🔍 Using mcp-optimist on handlers.ts: - **Total Lines**: 820 - **callToolHandler Complexity**: 126 (CRITICAL - should be <10) - **tryCallMemoryServer Complexity**: 30 (CRITICAL - should be <10) - **Cognitive Complexity**: 140 (High) - **Nesting Depth**: 5 levels ## Refactoring Plan 📋 ### Architecture: Layered Strategy Pattern ``` HandlerRegistry → Individual Handlers → OllamaService ↓ BaseHandler (validation, error handling) ``` ### Handlers to Create (TDD): 1. ⬜ ConsultOllamaHandler - calls Ollama API 2. ⬜ ListModelsHandler - lists available models 3. ⬜ CompareModelsHandler - compares multiple models 4. ⬜ RememberConsultHandler - stores in memory 5. ⬜ SequentialChainHandler - multi-step consultation 6. ⬜ HandlerRegistry - routes to handlers ## Next Steps 🎯 1. Create ConsultOllamaHandler with comprehensive tests 2. Extract common Ollama logic to OllamaService (already exists!) 3. Continue with remaining handlers 4. Wire up HandlerRegistry 5. Refactor main handlers.ts to use registry 6. Verify all complexity <10 ## Expected Impact 📊 - Complexity: 126 → <10 (92% reduction) - Maintainability: Dramatically improved - Testability: Each handler independently testable - Lines: 820 monolith → ~100 main + ~600 distributed handlers
