# FastMCP 🚀 Move fast and make things. *Made with 💙 by [Prefect](https://www.prefect.io/)* [](https://gofastmcp.com) [](https://discord.gg/uu8dJCgttd) [](https://pypi.org/project/fastmcp) [](https://github.com/PrefectHQ/fastmcp/actions/workflows/run-tests.yml) [](https://github.com/PrefectHQ/fastmcp/blob/main/LICENSE) --- The [Model Context Protocol](https://modelcontextprotocol.io/) (MCP) connects LLMs to tools and data. FastMCP gives you everything you need to go from prototype to production: ```python from fastmcp import FastMCP mcp = FastMCP("Demo 🚀") @mcp.tool def add(a: int, b: int) -> int: """Add two numbers""" return a + b if __name__ == "__main__": mcp.run() ``` ## Why FastMCP Building an effective MCP application is harder than it looks. FastMCP handles all of it. Declare a tool with a Python function, and the schema, validation, and documentation are generated automatically. Connect to a server with a URL, and transport negotiation, authentication, and protocol lifecycle are managed for you. You focus on your logic, and the MCP part just works: **with FastMCP, best practices are built in.** **That's why FastMCP is the standard framework for working with MCP.** FastMCP 1.0 was incorporated into the official MCP Python SDK in 2024. Today, the actively maintained standalone project is downloaded a million times a day, and some version of FastMCP powers 70% of MCP servers across all languages. FastMCP has three pillars: Servers Expose tools, resources, and prompts to LLMs. Apps Give your tools interactive UIs rendered directly in the conversation. Clients Connect to any MCP server — local or remote, programmatic or CLI. **[Servers](https://gofastmcp.com/servers/server)** wrap your Python functions into MCP-compliant tools, resources, and prompts. **[Clients](https://gofastmcp.com/clients/client)** connect to any server with full protocol support. And **[Apps](https://gofastmcp.com/apps/overview)** give your tools interactive UIs rendered directly in the conversation. Ready to build? Start with the [installation guide](https://gofastmcp.com/getting-started/installation) or jump straight to the [quickstart](https://gofastmcp.com/getting-started/quickstart). ## Run FastMCP in production with Horizon FastMCP is the standard way to build MCP servers. **[Prefect Horizon](https://www.prefect.io/horizon?utm_source=github&utm_medium=readme&utm_campaign=readme_horizon&utm_content=readme_body)** is the enterprise MCP gateway for running them safely. Built by the FastMCP team, Horizon packages the best practices we've learned shipping the world's most popular MCP framework. Deploy FastMCP servers from GitHub with branch previews and instant rollback. Create a private registry of every MCP your company uses. Secure access with SSO and tool-level RBAC. Get audit logs, observability, and governance across your MCP stack. Remix approved tools into purpose-built endpoints for teams and agents. Start with FastMCP.
