CodeAnalysis MCP Server

# MCP Enhancement - Implementation Summary ## Overview We have successfully implemented a comprehensive set of enhancements to the MCP Code Analysis project, focused on making the session management system more robust, flexible, and developer-friendly. The main goal was to reduce dependencies and improve the developer experience while maintaining production-ready features. ## Key Accomplishments ### 1. Modular Session Storage Architecture - Created a clean `SessionStore` interface to abstract storage details - Implemented a robust `MemorySessionStore` for development and testing - Maintained the existing `RedisSessionStore` with improved error handling - Developed a `sessionStoreFactory` with intelligent backend detection and fallback ### 2. Improved Developer Experience - Made Redis an optional dependency for development environments - Implemented automatic fallback to memory storage when Redis is unavailable - Simplified setup by eliminating Redis as a hard dependency - Enhanced error handling for Redis connectivity issues - Added status checks to verify Redis availability before use ### 3. Enhanced Session Management - Created feature-complete memory-based session implementation - Added TTL (time-to-live) support for memory sessions - Implemented locking mechanism for memory store - Ensured consistent behavior between Redis and memory implementations ### 4. Documentation and Examples - Created detailed architectural documentation in `docs/session-store.md` - Updated the `README.md` to explain Redis as an optional dependency - Added example code in `examples/session-store-example.js` - Updated existing documentation to reflect the new architecture ### 5. Testing - Created test scripts to verify session store functionality - Added examples that demonstrate correct behavior - Ensured compatibility with existing MCP client ## Technical Implementation Details 1. **Interface Consistency**: Ensured both Redis and memory implementations share identical interfaces 2. **Error Handling**: Improved error messages and graceful degradation 3. **Typing**: Added proper TypeScript types for better development experience 4. **ESM Compatibility**: Made the implementation work with ECMAScript modules 5. **Graceful Disconnection**: Ensured proper cleanup of resources ## Impact These enhancements have: - Simplified the onboarding process for new developers - Eliminated a major pain point (Redis requirement for development) - Made the system more resilient to infrastructure issues - Provided a cleaner, more maintainable architecture - Improved the overall developer experience ## Next Steps While the current enhancements provide a solid foundation, future improvements could include: 1. More comprehensive test coverage for session management 2. Additional storage backends (e.g., file-based, distributed cache) 3. Monitoring and metrics for session store performance 4. Additional examples for common usage patterns
