 "what": "FastMCP is a Python framework for building Model Context Protocol servers, clients and interactive apps. You declare a tool as an ordinary Python function and FastMCP generates the schema, validation and documentation; clients connect to any server by URL with transport, authentication and lifecycle handled. Apps give tools interactive UIs rendered inside the conversation, and there is an official TypeScript counterpart.",
 "why": "28k stars, talked about in 2 AI sources we track",
 "language": "Python",
 "requirements": [
  "Python and uv (recommended) for installation",
  "An MCP client to connect your server to, such as an AI assistant or coding agent",
  "For TypeScript projects: the separate fastmcp-ts package"
 ],
 "audience_note": "Python developers who want to give Claude, ChatGPT or any MCP client access to their own tools and data with minimal boilerplate.",
