Composio solves the hardest part of building useful agents - connecting to external services. It provides pre-built toolkits for GitHub (create PRs, manage issues), Slack (send messages, read channels), Gmail, Google Calendar, Notion, databases, and more. The key value is managed authentication - it handles OAuth flows, token refresh, and permission scoping. Your agent describes what it wants to do, and Composio translates that into the right API calls. Provider packages cover OpenAI Agents, the Claude Agent SDK, the Vercel AI SDK, LangChain, CrewAI, and Mastra, and sessions are also exposed as an MCP endpoint.

- Model-agnostic: provider packages format Composio tools for OpenAI Agents, Claude Agent SDK, Vercel AI SDK, LangChain, CrewAI, Mastra and others, and sessions are also exposed as an MCP endpoint. You bring your own model; Composio only bills LLM tokens when it runs a model for you in its Sandbox.
