Split monolithic task-master-core.js into separate function files within
the mcp-server/src/core/direct-functions/ directory. This change:
- Creates individual files for each direct function implementation
- Moves findTasksJsonPath to a dedicated utils/path-utils.js file
- Converts task-master-core.js to be a simple import/export hub
- Improves maintainability and organization of the codebase
- Reduces potential merge conflicts when multiple developers contribute
- Follows standard module separation patterns
Each function is now in its own self-contained file with clear imports and
focused responsibility, while maintaining the same API endpoints.
The function aimed to abstract the common flow within MCP tool methods (logging, calling direct function, handling result).
However, the established pattern (e.g., in ) involves the method directly calling the function (which handles its own caching via ) and then passing the result to . This pattern is clear, functional, and leverages the core utilities effectively.
Removing the unused simplifies , eliminates a redundant abstraction layer, and clarifies the standard implementation pattern for MCP tools.
Implemented LRU caching for the function to improve performance for repeated requests.
Key changes include:
- Added dependency.
- Introduced a reusable utility function in leveraging a .
- Refactored in to use the caching utility with a key based on task path, filter, and subtask flag.
- Modified to include the boolean flag in the final JSON response structure, nesting the original data under a key.
- Added function and corresponding MCP tool () for monitoring cache performance.
- Improved error handling in for cases where is not found.
This addresses the previous issue of the empty task list likely caused by stale cache entries and provides clear visibility into whether a response is served from the cache.
Relates to #23.9
This commit introduces a major refactoring of the MCP server implementation to prioritize direct function calls over CLI execution, enhancing performance and reliability. It also includes substantial updates to documentation for consistency and interlinking.
**MCP Server & Core Logic Refactoring:**
1. **Introduce Direct Function Wrappers ():**
* Created to house direct wrappers for core Task Master functions (imported from ).
* Implemented as the first wrapper, calling .
* Added utility within to centralize file location logic, removing duplication.
* Established the map for registering these wrappers.
2. **Enhance MCP Utilities ():**
* Added : A primary utility function to streamline MCP tool methods. It handles logging, argument processing (incl. project root normalization), calling the direct action function (e.g., ), processing results via , and formatting the final MCP response.
* Added : Standardizes processing of objects returned by direct function wrappers.
* Added : Filters sensitive/large fields (like , ) from responses sent to the MCP client.
* Added , , to support the new workflow.
* Refactored to use internally, simplifying its usage (though it's now primarily a fallback).
3. **Update MCP Tools (, ):**
* Refactored to use with , significantly simplifying the tool's method.
* Updated (initially) to use the improved (Note: further refactoring to use a direct wrapper for would follow the pattern).
**Documentation Enhancements:**
4. **Comprehensive Interlinking:** Added links across rule files (, , , , , ) to connect related guidelines, improving navigation.
5. **Standardize CLI Syntax ():** Removed legacy ℹ️ Initialized Perplexity client with OpenAI compatibility layer examples, reinforcing ℹ️ Initialized Perplexity client with OpenAI compatibility layer

6. **Add MCP Architecture & Workflow Sections:** Added detailed sections in and explaining MCP server structure and the workflow for adding new MCP tool integrations using the direct function pattern.
7. **Clarify MCP Role:** Updated and to better explain the MCP server's role and its specific utilities.
Overall, this establishes a cleaner, more performant, and maintainable pattern for integrating Task Master functionality with the MCP server, supported by improved documentation.
