Give your AI agents secure, authenticated access to 1,700+ apps
A large catalog of pre-built integrations spanning productivity, CRM, support, engineering, finance, HR, and e-commerce apps, each exposing callable actions to your agent.
Composio runs OAuth flows, stores and refreshes credentials, and enforces per-action permission scopes so agents act only where you allow them.
One managed MCP endpoint that connects Claude, ChatGPT, Codex, Cursor, and other MCP clients to your entire tool catalog in a few clicks.
Start background agents from events occurring across connected apps, so work can begin without a user prompt.
