## What it is
The Model Context Protocol (MCP) connects LLMs to tools and data. FastMCP is a full MCP application framework for servers, clients, and interactive apps. A server starts with ordinary Python: 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.

## When to use it
Reach for fastmcp when you want Claude, Cursor or any MCP client to reach a new tool, API or data source — it's written in Python and fits stacks tagged ai-agents, fastmcp, llm, mcp.
