The fastest way to enable your AI agents to take real‑world actions — without bespoke integrations or complex auth.
Composio lets agents act across apps with clean, reliable tools and built‑in authentication. No more juggling dozens of APIs or formats.
- 3000+ tools out of the box: Slack, GitHub, Notion, and more
- Fine‑grained access controls: enforce strict permissions per tool and user
- Event triggers: start agents/workflows from external events (e.g., new Slack message)
- Custom tools: adapt tools via modifiers for internal or proprietary APIs
- Framework integrations: OpenAI, Anthropic, LangChain, Vercel AI SDK, and more
- I/O processing hooks: clean and transform data for higher reliability
- Automatic tool‑call optimizations for better accuracy — free of cost
