+# Subtasks:
+## 1. Create Core MCP Server Module and Basic Structure [done]
+### Dependencies: None
+### Description: Create the foundation for the MCP server implementation by setting up the core module structure, configuration, and server initialization.
+### Details:
+Implementation steps:
+1. Create a new module `mcp-server.js` with the basic server structure
+2. Implement configuration options to enable/disable the MCP server
+3. Set up Express.js routes for the required MCP endpoints (/context, /models, /execute)
+4. Create middleware for request validation and response formatting
+5. Implement basic error handling according to MCP specifications
+6. Add logging infrastructure for MCP operations
+7. Create initialization and shutdown procedures for the MCP server
+8. Set up integration with the main Task Master application
+
+Testing approach:
+- Unit tests for configuration loading and validation
+- Test server initialization and shutdown procedures
+- Verify that routes are properly registered
+- Test basic error handling with invalid requests
+
+## 2. Implement Context Management System [done]
+### Dependencies: 23.1
+### Description: Develop a robust context management system that can efficiently store, retrieve, and manipulate context data according to the MCP specification.
+### Details:
+Implementation steps:
+1. Design and implement data structures for context storage
+2. Create methods for context creation, retrieval, updating, and deletion
+3. Implement context windowing and truncation algorithms for handling size limits
+4. Add support for context metadata and tagging
+5. Create utilities for context serialization and deserialization
+6. Implement efficient indexing for quick context lookups
+7. Add support for context versioning and history
+8. Develop mechanisms for context persistence (in-memory, disk-based, or database)
+
+Testing approach:
+- Unit tests for all context operations (CRUD)
+- Performance tests for context retrieval with various sizes
+- Test context windowing and truncation with edge cases
+- Verify metadata handling and tagging functionality
+- Test persistence mechanisms with simulated failures
+
+## 3. Implement MCP Endpoints and API Handlers [done]
+### Dependencies: 23.1, 23.2
+### Description: Develop the complete API handlers for all required MCP endpoints, ensuring they follow the protocol specification and integrate with the context management system.
+### Details:
+Implementation steps:
+1. Implement the `/context` endpoint for:
+   - GET: retrieving existing context
+   - POST: creating new context
+   - PUT: updating existing context
+   - DELETE: removing context
+2. Implement the `/models` endpoint to list available models
+3. Develop the `/execute` endpoint for performing operations with context
+4. Create request validators for each endpoint
+5. Implement response formatters according to MCP specifications
+6. Add detailed error handling for each endpoint
+7. Set up proper HTTP status codes for different scenarios
+8. Implement pagination for endpoints that return lists
+
+Testing approach:
+- Unit tests for each endpoint handler
+- Integration tests with mock context data
+- Test various request formats and edge cases
+- Verify response formats match MCP specifications
+- Test error handling with invalid inputs
+- Benchmark endpoint performance
+
+## 4. Implement Authentication and Authorization System [pending]
+### Dependencies: 23.1, 23.3
+### Description: Create a secure authentication and authorization mechanism for MCP clients to ensure only authorized applications can access the MCP server functionality.
+### Details:
+Implementation steps:
+1. Design authentication scheme (API keys, OAuth, JWT, etc.)
+2. Implement authentication middleware for all MCP endpoints
+3. Create an API key management system for client applications
+4. Develop role-based access control for different operations
+5. Implement rate limiting to prevent abuse
+6. Add secure token validation and handling
+7. Create endpoints for managing client credentials
+8. Implement audit logging for authentication events
+
+Testing approach:
+- Security testing for authentication mechanisms
+- Test access control with various permission levels
+- Verify rate limiting functionality
+- Test token validation with valid and invalid tokens
+- Simulate unauthorized access attempts
+- Verify audit logs contain appropriate information
+
+## 5. Optimize Performance and Finalize Documentation [pending]
+### Dependencies: 23.1, 23.2, 23.3, 23.4
+### Description: Optimize the MCP server implementation for performance, especially for context retrieval operations, and create comprehensive documentation for users.
+### Details:
+Implementation steps:
+1. Profile the MCP server to identify performance bottlenecks
+2. Implement caching mechanisms for frequently accessed contexts
+3. Optimize context serialization and deserialization
+4. Add connection pooling for database operations (if applicable)
+5. Implement request batching for bulk operations
+6. Create comprehensive API documentation with examples
+7. Add setup and configuration guides to the Task Master documentation
+8. Create example client implementations
+9. Add monitoring endpoints for server health and metrics
+10. Implement graceful degradation under high load
+
+Testing approach:
+- Load testing with simulated concurrent clients
+- Measure response times for various operations
+- Test with large context sizes to verify performance
+- Verify documentation accuracy with sample requests
+- Test monitoring endpoints
+- Perform stress testing to identify failure points
