Composio

Tool-use platform that gives agents access to 250+ apps

Live preview of composio.dev

Overview

Building tools for agents is mostly authentication. Composio solves that (OAuth flows, scoped tokens, refresh, multi-tenant credential storage) and exposes 250+ apps (Gmail, Slack, Notion, Linear, HubSpot, GitHub) as agent-ready actions.

This is the layer that turns "the agent can write text" into "the agent can actually send the email, file the ticket, update the CRM" without you writing twenty auth flows.

We pair Composio with whatever agent framework the client is on: Claude Agent SDK, LangGraph, CrewAI. It's framework-agnostic.
