Composio

What Composio does

Composio is an integration and authentication layer for AI agents. It provides more than 1,500 application toolkits, managed OAuth, triggers, tool calls, custom tools, sessions, and an MCP Gateway. Its differentiator is identity-aware execution: a product can connect each user to approved apps while Composio brokers scoped actions without exposing raw third-party credentials to the agent. This removes OAuth, refresh-token, schema, and connector maintenance, but makes Composio part of the product's security and availability boundary.

Pricing and cost

The fetched pricing FAQ says Hobby is hard-capped, needs no card, and includes 100,000 monthly tool calls, unlimited connections, custom tools and MCP, and three team members. Managed apps receive 20,000 free calls before an extra $0.0002 per call atop the base rate. Pro costs $29 monthly with usage credit and metered overages. A BAA add-on costs $0.0003 per tool call on Pro and is included on Enterprise. Premium tools can add provider charges plus a 5% platform fee. Spend caps and per-path measurement are essential.

How to evaluate it

Test one read, one write, one trigger, and one recovery path across two user accounts. Ensure account A cannot invoke account B's connection, revocation stops access promptly, retries do not duplicate writes, and logs identify the user, arguments, result, and error without exposing credentials. Measure managed-app, sandbox, proxy, and premium-tool paths separately because billing differs. Require approval for irreversible actions such as sending messages, deleting records, or moving money.

Pros

• Large toolkit catalog and managed OAuth reduce integration work
• Hard-capped Hobby tier prevents surprise bills
• MCP Gateway, triggers, sessions, and logs fit production agent patterns

Cons

• Base calls and multiple add-ons complicate cost modeling
• The broker becomes part of the security and availability boundary
• Connector abstractions may lag new or uncommon vendor API features

Practical use cases

• Adding user-authorized SaaS actions to an assistant
• Operating an MCP gateway across many tools and user connections
• Replacing bespoke OAuth and refresh-token code

Alternatives and buying checklist

Relevant alternatives are Zapier, BuildShip, Auth0, Anthropic MCP. Compare each with identical inputs, acceptance criteria, and security constraints. Track successful outcomes, setup time, human correction time, latency, failed actions, and monthly cost. Run edge cases, revoke a test user's access, inspect exports and audit logs, and simulate an integration outage. A polished demo is not evidence of production reliability.

This profile reflects vendor homepage and pricing research performed September 14, 2026. Pricing and entitlements can change, so confirm billing interval, included usage, overage rates, retention, support, and cancellation terms before signing. For agents that can take actions, begin read-only, grant least privilege, require approval for consequential writes, and keep a rollback path. Select based on measured quality after review time and operating cost are included—not the most impressive first prompt.
