# Atrax Improvement Plan This document outlines a systematic approach to improving the Atrax MCP proxy server codebase based on an in-depth analysis of the current implementation. ## Priority Improvements ### 1. Reduce Code Duplication in McpProxy - Extract common method handling patterns into shared helper functions - Create utility functions for handling `resources/list`, `tools/list`, and `prompts/list` requests - Implement a reusable pattern for capability detection and aggregation ### 2. Standardize Error Handling - Create a centralized error response utility - Define consistent error codes and messages across the codebase - Implement proper error propagation with context preservation - Ensure all error responses follow the MCP protocol specification ### 3. Enhance Type Safety - Improve the `determineServerForMethod` function with better TypeScript discrimination - Create more specific interface types for MCP method parameters and results - Leverage TypeScript's type system for enhanced compile-time safety - Add runtime type guards for improved validation ### 4. Refine Transport Abstraction - Extend the `Transport` interface to better handle MCP-specific message formats - Standardize event handling across transport implementations - Add better lifecycle management for transports - Improve error handling in transport implementations ### 5. Simplify Configuration Management - Refactor the configuration loading process with dedicated helper functions - Implement a more robust environment variable replacement mechanism - Add schema validation for configuration objects - Create a simplified configuration API for common operations ### 6. Improve Resource Registry Performance - Add indexing for faster resource, tool, and prompt lookups - Implement optimized search patterns for large registries - Add caching for frequently accessed resources - Improve conflict resolution strategies ## Medium-Term Improvements ### 7. Implement Modular Method Handling - Refactor method handling to use the Strategy pattern - Create dedicated handlers for each MCP method type - Implement a plugin architecture for extending method handlers - Improve routing logic for method dispatching ### 8. Add Response Format Normalization - Create a response normalization layer - Ensure consistent output formats across different server implementations - Add schema validation for server responses - Implement automatic format conversion for backward compatibility ### 9. Create a Request Validation Layer - Add middleware for request validation - Implement schema-based validation for all incoming requests - Add context tracking for request processing - Create detailed validation error messages ### 10. Centralize Capability Management - Enhance capability discovery with a centralized registry - Implement caching for server capabilities - Add capability negotiation based on client requirements - Improve capability detection reliability ## Long-Term Improvements ### 11. Implement Caching Strategy - Add a configurable caching mechanism for common requests - Implement time-based and request-based cache invalidation - Add cache headers for HTTP transport - Create a cache management API ### 12. Enhance Logging and Monitoring - Refine logging with operation IDs for request tracing - Implement structured logging for better analysis - Add performance metrics collection - Create a monitoring dashboard integration ### 13. Improve Documentation - Add comprehensive API documentation - Create usage examples for common scenarios - Document protocol compatibility details - Add architecture diagrams and flow charts ## Implementation Guidelines 1. **Incremental Changes**: Make changes one component at a time 2. **Test After Each Change**: Run tests after each significant change 3. **Maintain Compatibility**: Ensure backward compatibility throughout 4. **Document Changes**: Add inline documentation for complex logic 5. **Measure Performance**: Benchmark performance before and after changes ## Success Criteria - Reduced code complexity and improved maintainability - Enhanced type safety with minimal use of `any` types - Improved error handling with consistent messages - Better performance under high load - Complete protocol compliance with properly typed messages
