Composio
SDKs and CLI that connect AI agents to a thousand-plus app integrations
What it is
Composio is a set of TypeScript and Python SDKs plus a command-line tool that hand AI agents ready-made tools for apps like email, calendars, and code hosts, with per-user sessions and managed OAuth connections. Adapters translate those tools into the native format of OpenAI Agents, Claude Agent SDK, LangChain, CrewAI, Vercel AI SDK, and others, and each session can also be reached as a hosted MCP endpoint. Developers building agents that act on behalf of their users rely on it to skip writing and authenticating each integration themselves. It depends on Composio's hosted service and an API key.
