Optimized Memory MCP Server V2

# MCP Server Implementation Tasks ## Phase 1: Code Cleanup [x] ### Remove REST API Code [x] - [x] Remove FastAPI dependencies and imports - [x] Delete API endpoint definitions - [x] Remove API-specific error handlers - [x] Clean up API documentation files ### Restructure Project [x] - [x] Update project structure to MCP patterns - [x] Keep database code in db/ module - [x] Create resources package - [x] Create tools package ## Phase 2: MCP Server Implementation [x] ### Core Setup [x] - [x] Create FastMCP server instance - [x] Configure DATABASE_URL handling - [x] Set up SQLite connection management - [x] Implement error handling ### Resource Implementation [x] #### Entity Resources [x] - [x] Convert GET /entities to entities://list resource - [x] Convert GET /entities/{id} to entities://{id} resource - [x] Convert GET /relationships to relationships://{id} resource - [x] Convert GET /observations to observations://{id} resource #### IaC Resources [x] - [x] Convert GET /providers to providers://{provider}/resources resource - [x] Convert GET /ansible/collections to ansible://collections resource - [x] Convert GET /versions/collections to collections://{name}/versions resource - [x] Convert GET /search/entities to search://{query} resource ### Tool Implementation [x] #### Entity Management Tools [x] - [x] Convert POST /entities to create_entity() tool - [x] Convert PUT /entities/{id} to update_entity() tool - [x] Convert DELETE /entities/{id} to delete_entity() tool - [x] Convert POST /observations to add_observation() tool #### IaC Management Tools [x] - [x] Convert POST /providers to register_provider() tool - [x] Convert POST /ansible/collections to register_collection() tool - [x] Convert POST /versions/collections to add_version() tool - [x] Convert GET /analysis/providers to analyze_provider() tool ## Phase 3: Database Integration [x] ### Core Database [x] - [x] Verify SQLite schema compatibility - [x] Update database utility functions - [x] Implement connection pooling - [x] Add error handling ### Query Optimization [x] - [x] Optimize entity queries - [x] Improve relationship lookups - [x] Enhance observation retrieval - [x] Add proper indexing ## Phase 4: Testing [x] ### Unit Tests [x] - [x] Test MCP resources - [x] Test MCP tools - [x] Test database operations - [x] Test error handling ### Integration Tests [x] - [x] Test Claude Desktop compatibility - [x] Verify database operations - [x] Test resource patterns - [x] Validate tool execution ## Phase 5: Documentation [x] ### Code Documentation [x] - [x] Update docstrings for MCP patterns - [x] Document resource implementations - [x] Document tool implementations - [x] Add usage examples ### User Documentation [x] - [x] Update README.md - [x] Create MCP usage guide - [x] Document environment setup - [x] Add troubleshooting guide Dependencies: - REST API removal must be completed first - Database compatibility must be verified before MCP implementation - Resources must be implemented before tools - All features must be tested with Claude Desktop Notes: - Follow MCP SDK patterns exactly - Keep files under 250 lines - Use only DATABASE_URL environment variable - Focus on proper MCP Tools and Resources implementation - Ensure backward compatibility with existing database
