# Title: Implement MCP Server Functionality for Task Master using FastMCP
|
|
# Status: pending
|
|
# Dependencies: 22
|
|
# Priority: medium
|
|
# Description: Extend Task Master to function as an MCP server by leveraging FastMCP's JavaScript/TypeScript implementation for efficient context management services.
|
|
# Details:
|
|
This task involves implementing the Model Context Protocol server capabilities within Task Master. The implementation should:
|
|
|
|
1. Create a new module `mcp-server.js` that implements the core MCP server functionality
|
|
2. Implement the required MCP endpoints:
|
|
- `/context` - For retrieving and updating context
|
|
- `/models` - For listing available models
|
|
- `/execute` - For executing operations with context
|
|
3. Develop a context management system that can:
|
|
- Store and retrieve context data efficiently
|
|
- Handle context windowing and truncation when limits are reached
|
|
- Support context metadata and tagging
|
|
4. Add authentication and authorization mechanisms for MCP clients
|
|
5. Implement proper error handling and response formatting according to MCP specifications
|
|
6. Create configuration options in Task Master to enable/disable the MCP server functionality
|
|
7. Add documentation for how to use Task Master as an MCP server
|
|
8. Ensure the implementation is compatible with existing MCP clients
|
|
9. Optimize for performance, especially for context retrieval operations
|
|
10. Add logging for MCP server operations
|
|
|
|
The implementation should follow RESTful API design principles and should be able to handle concurrent requests from multiple clients.
|
|
|
|
# Test Strategy:
|
|
Testing for the MCP server functionality should include:
|
|
|
|
1. Unit tests:
|
|
- Test each MCP endpoint handler function independently
|
|
- Verify context storage and retrieval mechanisms
|
|
- Test authentication and authorization logic
|
|
- Validate error handling for various failure scenarios
|
|
|
|
2. Integration tests:
|
|
- Set up a test MCP server instance
|
|
- Test complete request/response cycles for each endpoint
|
|
- Verify context persistence across multiple requests
|
|
- Test with various payload sizes and content types
|
|
|
|
3. Compatibility tests:
|
|
- Test with existing MCP client libraries
|
|
- Verify compliance with the MCP specification
|
|
- Ensure backward compatibility with any MCP versions supported
|
|
|
|
4. Performance tests:
|
|
- Measure response times for context operations with various context sizes
|
|
- Test concurrent request handling
|
|
- Verify memory usage remains within acceptable limits during extended operation
|
|
|
|
5. Security tests:
|
|
- Verify authentication mechanisms cannot be bypassed
|
|
- Test for common API vulnerabilities (injection, CSRF, etc.)
|
|
|
|
All tests should be automated and included in the CI/CD pipeline. Documentation should include examples of how to test the MCP server functionality manually using tools like curl or Postman.
