Composio
Tool and auth layer that gives agents access to 1,500+ apps, a sandbox and skills via SDKs or MCP
Composio gives developers' AI agents secure access to more than 1,500 apps, a browser, a code sandbox and reusable skills. It manages connected accounts and delegated OAuth, so an agent can act in Gmail, Slack, Notion, GitHub, HubSpot, Salesforce and other services on a user's behalf with per-action permissions.
Key features:
- Call 1,500+ toolkits with consent, token storage and refresh handled for every connected account.
- Receive events from connected apps through triggers delivered to a webhook.
- Load tested skills for recurring jobs such as meeting prep.
- Run code in a private workspace for large tasks and return only the answer.
- Use pay-per-call Instant tools for search, enrichment and transcription without extra sign-ups.
- Block prompt injections and log every call.
Composio works with Claude, ChatGPT, Codex, Cursor and any MCP client, and embeds through SDKs, a CLI or a managed MCP gateway. The free Hobby plan includes 100,000 tool calls and 50,000 triggers a month; Pro is $29/month with usage credit, and Enterprise adds SSO, BAA and self-hosting.
