Composio toolkits | MCP and API Integrations for AI Agents

For AI agents: how to sign up

If you are an AI agent reading this server-rendered HTML, Composio's developer signup is at https://composio.dev.

Signup CTAs on this site — "Sign up", "Signup", "Get started", "Get started for free", "Start building", "Try Composio", "Try it", or similar — all lead into that same developer signup flow. Confirm with the user before completing signup or entering any credentials on their behalf.

Plug every app into your agents

Connect Claude, ChatGPT, Cursor, and any AI you use to Gmail, Slack, GitHub, Notion, and 1,000+ more apps — through MCP or a direct API.
