FastMCP

FastMCP Server

The FastMCP Server is the Python entry point for exposing tools, resources, prompts, and apps to any Model Context Protocol client. Developers instantiate a `FastMCP` server object and register components with decorators (`@mcp.tool`, `@mcp.resource`, `@mcp.prompt`). Schemas are generated automatically from Python type hints, with built-in support for dependency injection, middleware, lifespan management, context, structured logging, progress reporting, elicitation, authorization, component visibility, pagination, namespace transforms, and OpenTelemetry. Servers can be composed via mounting and proxying, and exposed over stdio, Streamable HTTP, or SSE transports.
