Try it in a small test task inside your agent workflow.
FastMCP is a Python framework that makes creating MCP servers as easy as writing a decorator. You define Python functions, add @mcp.tool(), and they become available to any AI coding agent that supports MCP.
FastMCP is the fastest way to build MCP servers in Python. Inspired by FastAPI's design philosophy, it provides a clean, type-safe API for exposing tools, resources, and prompts to AI agents. It handles all the MCP protocol complexity — transport, JSON-RPC, server lifecycle — so you focus on your tool logic. Supports stdio and SSE transports out of the box. Great for prototyping MCP tools quickly or building production-grade MCP servers.
Strong trust signals; still review the README and permissions before production use.
