FastMCP is a Pythonic framework for building Model Context Protocol (MCP) servers, clients, and interactive applications. It handles schema generation, validation, transport negotiation, authentication, and lifecycle management so developers can focus on their business logic.
Use cases
- expose Python functions as LLM tools via MCP
- connect a local or remote LLM agent to an MCP server
- build interactive AI-powered dashboards with Prefab UI
- create stateful AI assistants that preserve user context across requests
- generate standard MCP JSON configuration files for any compatible client
- run MCP servers in production with built‑in authentication and routing
When to choose
- You need a high‑level, production‑ready framework for MCP‑based LLM tool integration.
- You want automatic schema and validation for Python functions used by LLMs.
- You require support for both legacy and new sessionless MCP protocol versions.
When to avoid
- You are not using the Model Context Protocol or LLM tool orchestration.
- You need a low‑level custom transport implementation not covered by FastMCP.
- Your project is limited to a language other than Python.
