The Tool-Calling & Auth Layer for AI Agents
Give your agents secure, managed access to 1,000+ apps — auth, tool calls, and sandboxed execution handled for you.
Composio is the integration and authentication layer that lets an AI agent actually do things in other systems. Instead of writing and maintaining a bespoke connector (plus its OAuth dance) for every app an agent needs, builders point Composio at the target apps and get back ready-to-use, function-callable tools with secure delegated auth, just-in-time tool definitions, sandboxed execution, and parallel calls across 1,000+ integrations — Gmail, Notion, Slack, GitHub, Linear, CRMs, and the rest.
It slots in beneath the agent frameworks (LangChain, CrewAI, the OpenAI/Anthropic SDKs) and speaks MCP, so it complements rather than replaces tools like N8n or Openclaw: those orchestrate workflows; Composio supplies the authenticated reach into third-party apps. For Dojo members building agents, it's the most direct answer to the recurring "how do I wire my agent into Affinity / Notion / Drive without it being a multi-day auth project" question — the plumbing is the product.
