# Composio

> Tooling and authentication layer connecting AI agents to external applications

Composio is an open-source integration framework that gives AI agents access to over a thousand external tools and APIs. It manages user authentication, dynamic tool discovery, and runtime sandboxes so developers can connect models to real-world actions without writing manual integrations. It supports TypeScript, Python, MCP clients, and major agent frameworks like LangChain, OpenAI Agents, and Claude.
