MCP is essential for connecting Large Language Models (LLMs) with external tools and data, enabling them to perform complex tasks. FastMCP simplifies this process, providing a full application framework for servers, clients, and interactive applications, making it the de facto standard for MCP development.\n\n## Installation\n\nGetting started with FastMCP is straightforward. You can add it to your project using `uv`:\n\nbash\nuv add fastmcp\n\n\nFor complete installation instructions, including verification and upgrading, refer to the [official Installation Guide](https://gofastmcp.com/getting-started/installation).\n\n## Examples\n\nFastMCP allows you to declare tools using ordinary Python functions. Here's a simple example of an MCP server:\n\npython\nfrom fastmcp import FastMCP\n\nmcp = FastMCP(\"Demo ?\")\n\n@mcp.tool\ndef add(a: int, b: int) -> int:\n    \"\"\"Add two numbers\"\"\"\n    return a + b\n\nif __name__ == \"__main__\":\n    mcp.run()\n\n\nThis code snippet demonstrates how easily you can define a tool, with schema, validation, and documentation generated automatically.\n\n## Why Use FastMCP\n\nBuilding effective MCP applications can be challenging, but FastMCP abstracts away much of the complexity. It automatically handles schema generation, validation, and documentation for your tools, and manages transport negotiation, authentication, and protocol lifecycle for clients. This allows developers to focus on core logic, ensuring that best practices are built in from the start.\n\nFastMCP is structured around three core pillars:\n\n*   **Servers**: Expose Python functions as MCP-compliant tools, resources, and prompts to LLMs. ([Learn more about Servers](https://gofastmcp.com/servers/server))\n*   **Clients**: Connect to any MCP server, local or remote, with full protocol support. ([Learn more about Clients](https://gofastmcp.com/clients/client))\n*   **Apps**: Provide interactive user interfaces for your tools, rendered directly within conversations. ([Learn more about Apps](https://gofastmcp.com/apps/overview))\n\nFor TypeScript developers, [FastMCP for TypeScript](https://github.com/PrefectHQ/fastmcp-ts) offers the same powerful features and concepts.\n\n## Links\n\nExplore FastMCP further with these resources:\n\n*   [Official Documentation](https://gofastmcp.com)\n*   [GitHub Repository](https://github.com/PrefectHQ/fastmcp)\n*   [Join the Community on Discord](https://discord.gg/uu8dJCgttd)","metrics":{"detailViews":0,"githubClicks":0},"dates":{"published":null,"modified":"2026-08-11T07:30:50.000Z"}}
