MCP Builder is an Agent Skill that guides you in creating high-quality Model Context Protocol servers, which let LLMs interact with external services through well-designed tools. It covers both Python, using FastMCP, and Node/TypeScript, using the MCP SDK. Use it when you want to integrate an external API or service into an MCP server and want guidance on doing it well rather than from scratch.
