Build MCP servers to connect external APIs to Claude using Python FastMCP and Node SDK patterns.

About

An agent-building skill for creating MCP servers that expose external APIs to Claude, covering both Python FastMCP and Node SDK approaches. Developers use it to give agents new tools by wrapping a third-party API as a Model Context Protocol server.
