What is Composio?

Composio connects AI assistants and custom agents to more than 1,500 apps and toolkits. It lets them retrieve information and take actions across services such as Gmail, Slack, Notion, Salesforce, and GitHub. Users can connect an existing assistant through MCP or use the CLI, while developers can embed tool access and account authentication into their own applications through SDKs.

The platform handles OAuth consent, token storage, refresh, and scopes for connected accounts. Agents can find available actions, follow reusable task skills, run code in a private workspace, and respond to events from connected apps. Teams can share accounts, skills, and usage budgets rather than configuring each assistant separately.

Access controls and action logs help teams manage what agents can do. An optional Firewall uses decision models to check tool requests and results against policies, including checks for hidden instructions. Enterprise options add identity management, customer-managed encryption keys, and deployment choices. The free Hobby plan has monthly usage caps; paid usage and selected security features require an upgrade or add-on.

What can Composio do?

  • App connections and authentication

    Connect agents to 1,500+ toolkits with managed OAuth consent, token refresh, and account permissions.

  • SDKs, CLI, and MCP gateway

    Add tools to existing assistants or integrate them into custom agents through SDKs, a CLI, and a managed MCP endpoint.

  • Event-driven triggers

    Deliver events from connected apps to webhooks to start background agent workflows.

  • Skills and code execution

    Give agents reusable task instructions and a private workspace for running code on larger jobs.

  • Policy checks and action logs

    Inspect agent activity and use the optional Firewall to check tool requests and results against policies.

  • Shared team configuration

    Share connected accounts, skills, and usage budgets across teammates and their AI assistants.

Frequently asked questions

What does the free plan include?

Hobby includes 100,000 tool calls and 50,000 triggers per month, unlimited connected accounts, and three team members. It requires no credit card and pauses usage when a cap is reached.

How much does Pro cost?

Which AI assistants can use Composio?

Composio supports connections for Claude, ChatGPT, Codex, Cursor, and other MCP clients. Developers can also integrate it with frameworks including OpenAI, Anthropic, Vercel AI SDK, and LangChain.

Can I bring my own tools and credentials?

All plans support custom tools, external MCP servers, and self-managed credentials. With self-managed credentials, you pass access tokens at execution time, and Composio does not store or refresh them.

Do managed app connections have different allowances?

Using your own OAuth application or API keys provides the full 100,000 free monthly tool-call allowance. Composio-managed shared OAuth apps include 20,000 free calls per month, then add $0.0002 per call on top of the base rate.
