FastMCP is a Python framework from Prefect (originating with Jeremiah Lowin) for building Model Context Protocol servers and clients with minimal boilerplate. It is a builder framework, not a ready-to-run server. Naming history matters: FastMCP v1 was donated into the official MCP Python SDK, and this actively developed successor revived the name — confirm you're pulling `fastmcp` (this project) versus the official `mcp` SDK, and review its client defaults (e.g. dynamic client registration) when connecting hosted clients.
