mcp-use is the consumer side of MCP: an open-source library that connects a model or agent to one or many MCP servers, handling the handshake and tool discovery so you do not write client plumbing.

It is model-agnostic and works alongside common agent frameworks, turning a set of MCP servers into tools an agent can simply use.

Where it's ideally used

A fit when you are building an agent and want to consume existing MCP servers without writing client code.

Where it doesn't fit

A client, not a server framework — not the tool for exposing your own capability over MCP.
