FastMCP
Pythonic framework for building MCP servers. Decorators for tools, resources, and prompts. Officially incorporated into the Python SDK.
FastMCP is the Python framework that makes writing an MCP server feel like writing a Flask or FastAPI app. You decorate functions with @mcp.tool, @mcp.resource, or @mcp.prompt and FastMCP handles the MCP protocol, transport negotiation, and schema generation. Version 1.0 was incorporated into the official Anthropic Python SDK, giving it a clear canonical home. The v2 line adds higher-level features on top: composable servers, auth middleware, and HTTP streaming. For any developer building their own MCP server in Python, FastMCP is the starting point and has effectively no competition at the same ergonomic tier.
