# Title: Complete MCP Server Implementation for Task Master using FastMCP
|
|
# Status: pending
|
|
# Dependencies: 22
|
|
# Priority: medium
|
|
# Description: Finalize the MCP server functionality for Task Master by leveraging FastMCP's capabilities, transitioning from CLI-based execution to direct function imports, and optimizing performance, authentication, and context management.
|
|
# Details:
|
|
This task involves completing the Model Context Protocol (MCP) server implementation for Task Master using FastMCP. Key updates include:
|
|
|
|
1. Transition from CLI-based execution to direct Task Master function imports for improved performance and reliability.
|
|
2. Enhance authentication and authorization mechanisms using FastMCP's built-in capabilities (e.g., API keys, OAuth, or JWT).
|
|
3. Refactor context management to align with best practices for handling large context windows, metadata, and tagging.
|
|
4. Optimize server performance by leveraging FastMCP's efficient transport mechanisms (e.g., stdio or SSE) and implementing caching for frequently accessed contexts.
|
|
5. Integrate the ModelContextProtocol SDK directly to streamline resource and tool registration.
|
|
6. Update documentation to include examples of using the MCP server with FastMCP, detailed setup instructions, and client integration guides.
|
|
|
|
The implementation must ensure compatibility with existing MCP clients and follow RESTful API design principles, while supporting concurrent requests and maintaining robust error handling.
|
|
|
|
# Test Strategy:
|
|
Testing for the updated MCP server functionality should include:
|
|
|
|
1. Unit tests:
|
|
- Validate direct function imports for Task Master tools.
|
|
- Test updated authentication and authorization mechanisms.
|
|
- Verify context management operations (CRUD, metadata, windowing).
|
|
|
|
2. Integration tests:
|
|
- Test the MCP server with FastMCP's stdio and SSE transport modes.
|
|
- Verify end-to-end request/response cycles for each endpoint.
|
|
- Ensure compatibility with the ModelContextProtocol SDK.
|
|
|
|
3. Performance tests:
|
|
- Benchmark response times for context operations with large datasets.
|
|
- Test caching mechanisms and concurrent request handling.
|
|
- Measure memory usage and server stability under load.
|
|
|
|
4. Security tests:
|
|
- Validate the robustness of authentication/authorization mechanisms.
|
|
- Test for vulnerabilities such as injection attacks, CSRF, and unauthorized access.
|
|
|
|
5. Documentation validation:
|
|
- Ensure all examples in the documentation are accurate and functional.
|
|
- Verify manual testing workflows using tools like curl or Postman.
|
|
|
|
All tests should be automated and integrated into the CI/CD pipeline to ensure consistent quality.
