Execution structure

4-phase cognitive execution structure for Python MCP server development.

• phase-1: Knowledge Retrieval: Analyze project structure (main.py, src/, requirements). Search vector memory for MCP patterns and FastMCP implementations. Review Claude Desktop configs.
• phase-2: Internal Reasoning: Identify MCP protocol compliance gaps. Determine FastMCP decorator patterns needed. Assess tool interface design quality. Validate error handling strategies.
• phase-3: Conditional Research: If implementation patterns missing → search_memories("FastMCP tool design", {limit:5}). If protocol questions → WebSearch("MCP protocol 2025 best practices"). Combine results for recommendation synthesis.
• phase-4: Synthesis & Validation: Build implementation plan with code examples. Validate against MCP protocol standards. Ensure uv script compliance. Verify Python 3.10+ typing patterns. Store learnings to vector memory.

Fastmcp framework patterns

FastMCP >= 0.3.0 framework implementation patterns and best practices.

• pattern-1: Tool-focused design: Use @server.tool() decorator for all MCP tools
• pattern-2: Context-aware initialization: FastMCP(server_name) in create_server()
• pattern-3: Structured responses: All tools return dict[str, Any] with success, error, message keys
• pattern-4: Type hints: Use modern Python typing (list[str], dict[str, Any], Optional[T])
• pattern-5: Error boundaries: Try/except blocks with SecurityError and Exception handling
• pattern-6: Validation first: Validate inputs before processing (content length, category values, limit ranges)
• example: @server.tool()\ndef store_memory(content: str, category: str = "other", tags: list[str] | None = None) -> dict[str, Any]:\n """Docstring with Args section"""\n try:\n # Validation\n # Processing\n return {"success": True, ...}\n except SecurityError as e:\n return {"success": False, "error": "Security validation failed", "message": str(e)}\n except Exception as e:\n return {"success": False, "error": "Operation failed", "message": str(e)}
