Applied automated linting and formatting:
- Fixed missing newlines at end of files
- Adjusted line wrapping for better readability
- Fixed multi-line string formatting in tests
- No functional changes, only style improvements
All 43 tests still passing after formatting changes.
Comprehensive update to MCP server error handling:
Error Handling Improvements:
- Applied MCPErrorFormatter to all remaining MCP tool files
- Replaced all hardcoded timeout values with configurable timeout system
- Converted all simple string errors to structured error format
- Added proper httpx exception handling with detailed context
Tools Updated:
- document_tools.py: All 5 document management tools
- version_tools.py: All 4 version management tools
- feature_tools.py: Project features tool
- project_tools.py: Remaining 3 project tools (get, list, delete)
- task_tools.py: Remaining 4 task tools (get, list, update, delete)
Test Improvements:
- Removed backward compatibility checks from all tests
- Tests now enforce structured error format (dict not string)
- Any string error response is now considered a bug
- All 20 tests passing with new strict validation
This completes the error handling refactor for all MCP tools,
ensuring consistent client experience and better debugging.
Critical improvements to MCP server reliability and client experience:
Error Handling:
- Created MCPErrorFormatter for consistent error responses across all tools
- Provides structured errors with type, message, details, and actionable suggestions
- Helps clients (like Claude Code) understand and handle failures gracefully
- Categorizes errors (connection_timeout, validation_error, etc.) for better debugging
Timeout Configuration:
- Centralized timeout config with environment variable support
- Different timeouts for regular operations vs polling operations
- Configurable via MCP_REQUEST_TIMEOUT, MCP_CONNECT_TIMEOUT, etc.
- Prevents indefinite hangs when services are unavailable
Module Registration:
- Distinguishes between ImportError (acceptable) and code errors (must fix)
- SyntaxError/NameError/AttributeError now halt execution immediately
- Prevents broken code from silently failing in production
Polling Safety:
- Fixed project creation polling with exponential backoff
- Handles API unavailability with proper error messages
- Maximum attempts configurable via MCP_MAX_POLLING_ATTEMPTS
Response Normalization:
- Fixed inconsistent response handling in list_tasks
- Validates and normalizes different API response formats
- Clear error messages when response format is unexpected
These changes address critical issues from PR review while maintaining
backward compatibility. All 20 existing tests pass.
- Add explicit type annotations for params dictionaries to resolve mypy errors
- Remove trailing whitespace from blank lines (W293 ruff warnings)
- Ensure type safety in task_tools.py and document_tools.py
- Rename src/mcp to src/mcp_server for clarity
- Update all internal imports to use new path
- Create features/projects directory for modular tool organization
- Add separate, simple project tools (create, list, get, delete, update)
- Keep consolidated tools for backward compatibility (via env var)
- Add USE_SEPARATE_PROJECT_TOOLS env var to toggle between approaches
The new separate tools:
- Solve the async project creation context loss issue
- Provide clearer, single-purpose interfaces
- Remove complex PRP examples for simplicity
- Handle project creation polling automatically
