How do I test my MCP server safely?

The guide recommends using evaluation harnesses or running servers in isolated environments like tmux to prevent the long-running process from hanging your main development terminal.

What is an MCP server?

A Model Context Protocol (MCP) server is a service that provides tools and resources, allowing LLMs to interact securely with external APIs, databases, and services.

What are the key components of an MCP implementation?

Implementation involves defining input schemas (Pydantic/Zod), core tool logic, shared utilities for pagination/auth, and descriptive metadata for the LLM to understand tool purpose.

Does this skill support both Python and Node.js?

Yes, it provides specific implementation paths and best practices for both Python (FastMCP/SDK) and Node/TypeScript environments.

Why focus on 'Agent-Centric' design?

Agents have limited context windows. This skill teaches you to build tools that return high-signal information and provide actionable error messages to improve agent success rates.

API開発

Builds high-quality Model Context Protocol (MCP) servers to enable seamless interaction between LLMs and external services.

This skill provides a comprehensive, step-by-step workflow for developing Model Context Protocol (MCP) servers using Python or Node/TypeScript. It guides developers through deep research, agent-centric design principles, and the implementation of robust tools optimized for AI context windows. By focusing on workflow-oriented design rather than simple API wrapping, it ensures that AI agents can effectively accomplish real-world tasks with clear error handling and high-signal data responses. The skill also includes a rigorous evaluation framework to verify server performance and reliability.
