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
