Introduction

Composio is the integration layer for AI agents. Instead of building OAuth flows, managing API keys, and writing API wrappers for every tool your agent needs, Composio provides:

  • 250+ pre-built integrations: GitHub, Slack, Jira, Linear, Notion, Google Workspace, Salesforce, databases, and more
  • Managed authentication: OAuth2, API keys, JWT — Composio handles the auth flow for each service
  • MCP server mode: Run Composio as an MCP server for Claude Code, Cursor, and other MCP-compatible tools
  • Framework agnostic: Works with OpenAI, LangChain, CrewAI, AutoGen, Anthropic SDK, Vercel AI SDK
  • Action-level granularity: Don't expose entire APIs — pick specific actions (e.g., "create issue" but not "delete repo")
  • Execution environments: Run tools in sandboxed Docker containers for safety

Think of Composio as "Zapier for AI agents" — but designed for programmatic use, not visual workflows.

FAQ

Q: How does auth work? A: Run composio add github and it opens an OAuth flow in your browser. Tokens are securely stored and auto-refreshed. Your agent never sees raw credentials.

Q: Can I use it with Claude Code? A: Yes, two ways: (1) Use the Python SDK in your scripts, or (2) Run composio mcp start to expose all tools as an MCP server that Claude Code can connect to.

Q: What if I need a tool that's not in the 250+ list? A: You can create custom tools with the Composio SDK. Define the API schema and auth method, and it integrates seamlessly.

Q: Is it free? A: Open-source with a free tier. Self-hostable. The cloud version has a generous free plan for individual developers.
