1000+ pre-authenticated toolkits, per-user sessions, triggers, and a workbench for your AI agent.
Everything you need to ship production agents.
Tools that resolve by intent.
Smart tool search over 1000+ apps — surfaced just-in-time, with the right scope.
Auth and context, per end-user.
OAuth, API keys, and tokens scoped to each user — refreshed automatically.

Run arbitrary code, safely.
A workbench pre-wired with your user's connected accounts and 1000+ tools.
const result = await composio.workbench.run(`
const issues = await tools.LINEAR_LIST_ISSUES();
const summary = await ai.summarize(issues);
await tools.SLACK_POST({ channel, text: summary });
