Optimized Memory MCP Server V2

# MCP Server Integration Tasks ## Overview ### Project Scope Refactor existing MCP server implementation to properly use the FastMCP SDK, replacing current low-level Server implementation. ### Goals and Objectives - Implement proper FastMCP integration - Fix current test failures - Ensure Claude Desktop compatibility - Maintain database functionality ### Key Constraints - Must maintain existing database schema - Must support async operations - Must be compatible with Claude Desktop - Must pass all existing tests after refactoring ## Task Categories ### [✓] 1. Core Server Implementation **Priority**: High **Dependencies**: None #### Description Replace low-level Server implementation with FastMCP. #### Acceptance Criteria - [x] Server initialization uses FastMCP - [x] All server capabilities properly registered - [x] Async operations handled through FastMCP - [x] Database integration maintained - [x] Logging system integrated #### Resources - MCP Python SDK documentation - FastMCP examples - Current server implementation ### [✓] 2. Tool System Migration **Priority**: High **Dependencies**: Core Server Implementation #### Description Move all tool implementations to use FastMCP decorators. #### Acceptance Criteria - [✓] All tools use @mcp.tool() decorator - [✓] Tool signatures properly typed - [✓] Async operations correctly implemented - [✓] Documentation provided for all tools - [✓] Database operations properly integrated - [✓] Tool error handling implemented #### Resources - FastMCP tool documentation - Current tool implementations - Database models ### [✓] 3. Resource System Implementation **Priority**: High **Dependencies**: Core Server Implementation #### Description Implement all resources using FastMCP resource system. #### Acceptance Criteria - [x] All resources use @mcp.resource() decorator - [x] Resource paths follow MCP conventions - [x] Return types properly specified - [x] Async operations implemented - [x] Documentation provided - [x] Error handling implemented #### Resources - FastMCP resource documentation - Current resource implementations ### [✓] 4. Test Infrastructure Update **Priority**: High **Dependencies**: Tool System, Resource System #### Description Update test infrastructure to work with FastMCP. #### Acceptance Criteria - [x] Test client uses FastMCP methods - [x] Mock implementations removed - [x] Async testing properly implemented - [x] Database testing integrated - [x] All test utilities updated - [x] Enhanced error validation implemented - [x] Comprehensive test coverage for error scenarios - [x] Detailed assertion messages added #### Resources - FastMCP testing documentation - Current test implementations - pytest-asyncio documentation - Error handling specifications ### [✓] 5. Database Integration **Priority**: Medium **Dependencies**: Core Server Implementation #### Description Update database models and operations to work with FastMCP. #### Acceptance Criteria - [x] Models properly initialized - [x] Async operations supported - [x] Transactions properly handled - [x] Error handling implemented - [x] Foreign key constraints maintained - [x] Comprehensive validation implemented - [x] Concurrent operation handling added - [x] Database cleanup procedures added #### Resources - SQLAlchemy documentation - Current database models - FastMCP database examples - Database integration tests ### [✓] 6. Test Suite Updates **Priority**: Medium **Dependencies**: Test Infrastructure #### Description Update all individual tests to work with new implementation. #### Acceptance Criteria - [x] All tests pass - [x] Async operations properly tested - [x] Database operations verified - [x] Error scenarios covered - [x] Integration tests updated - [x] Comprehensive error validation added - [x] Database integration tests enhanced - [x] Claude Desktop compatibility verified #### Resources - Updated test infrastructure - Current test suite - FastMCP testing examples - Error handling specifications - Claude Desktop integration guide ### [🔄] 7. Documentation **Priority**: Low **Dependencies**: All implementation tasks #### Description Update all documentation to reflect new implementation. #### Acceptance Criteria - [x] README updated - [x] API documentation current - [x] Setup instructions correct - [x] Testing documentation updated - [x] Examples provided - [x] Error handling documented - [x] Database schema documented - [x] Testing patterns documented #### Resources - Current documentation - FastMCP documentation - Implementation details - Error handling specifications - Database schema documentation - Test coverage reports ## Implementation Order 1. Core Server Implementation 2. Tool System Migration 3. Resource System Implementation 4. Test Infrastructure Update 5. Database Integration 6. Test Suite Updates 7. Documentation ## Validation Steps ### Pre-Implementation - [x] All tasks identified - [x] Dependencies verified - [x] Resources available - [x] Scope confirmed ### During Implementation - [✓] Regular test execution - [✓] Functionality verification - [✓] Integration testing - [✓] Performance validation ### Post-Implementation - [ ] All tests passing - [ ] Documentation complete - [ ] Claude Desktop integration verified - [ ] Performance acceptable ## Notes - Tasks must be implemented in order - No scope changes permitted after start - Only completion status can be updated - All changes must align with FastMCP patterns
