Can I use FastMCP with FastAPI?

Yes, FastMCP is designed to integrate seamlessly with ASGI frameworks like FastAPI and Starlette, allowing you to share server lifespans and application logic.

How do I run a FastMCP server?

You can run it as a standard Python script, use the FastMCP CLI for development mode, or deploy it as an HTTP service via transport flags.

What is FastMCP used for?

FastMCP is a framework used to build servers that follow the Model Context Protocol, allowing LLMs like Claude to securely use your custom Python tools, data resources, and prompts.

Does FastMCP support authentication?

Yes, it provides multiple patterns including JWT verification, OAuth Proxy for providers like GitHub and Google, and a full OAuth 2.0 provider implementation.

What storage backends are available?

It supports Memory, Disk (with Fernet encryption), Redis, DynamoDB, MongoDB, and several other databases for managing persistent state and token caches.

Desarrollo de API

Builds high-performance Model Context Protocol (MCP) servers in Python to expose tools, resources, and prompts to LLMs.

Acerca de

FastMCP is a robust Python framework designed for creating Model Context Protocol (MCP) servers that bridge the gap between Large Language Models and external data or functions. It provides a production-ready ecosystem featuring flexible storage backends like Redis and Disk, a modular middleware system for logging and rate limiting, and comprehensive OAuth authentication patterns. Whether you are building custom tools for Claude or deploying complex AI integrations via FastMCP Cloud, this skill provides the patterns and best practices needed to implement secure, scalable, and type-safe MCP servers with minimal boilerplate.
