Composio is an integration and tool-infrastructure platform for AI agents that need authenticated actions across business applications. Current public copy and the GitHub repository describe 1,000+ toolkits, tool search, context management, managed authentication, delegated access, sessions, a CLI, MCP Gateway, and a sandboxed workbench. The stronger framing is no longer a small connector catalog; it is a managed auth and execution layer for agents that need Gmail, Slack, Notion, GitHub, Salesforce-style workflows, or custom API tools without rebuilding OAuth, token refresh, permissions, and integration maintenance from scratch.
The docs now steer many MCP use cases toward sessions and show single-toolkit MCP as one path rather than the only or best experience. That means the base page should separate Composio as the broader platform from its MCP Gateway and single-toolkit MCP modes. Useful buyer caveats are also important: teams should evaluate which app connectors are production-ready for their exact workflow, whether they want Composio-managed auth or custom/white-labeled auth, how sessions map to end users, and how much operational lock-in they accept when routing critical third-party actions through a vendor platform.
Pricing has moved beyond the older Hobby/Pro wording. The public pricing page lists a Totally Free plan at $0/month with 20K tool calls, a $29/month tier with 200K tool calls and $0.299 per additional 1K calls, a Serious Business plan at $229/month with 2M tool calls and $0.249 per additional 1K calls, and Enterprise custom pricing with user accounts, dedicated SLA and SOC-2 language, custom API volume, and VPC/on-prem options. The MIT-licensed GitHub repo was active and near 29K stars at verification time, but review copy should avoid unverified error-reduction or connector-count claims unless they are rechecked against current docs.
