Composio for Claude Code

Act on 1,000+ apps — Google Workspace, Slack, GitHub, Notion, Linear, Jira, HubSpot, and more — directly from Claude Code. Your agent decides what to do; Composio handles the rest: OAuth, permissions, and finding the right tool for each task. No API keys, no config files.

What you can do

• Act on any connected app — "send a Slack message to #eng", "list my open GitHub PRs", "add a lunch event to my calendar tomorrow". Claude finds the tool and runs it.
• Run cross-app workflows — turn the latest GitHub PR into a Linear issue and announce it in Slack; draft a Notion doc from a calendar event.
• Connect apps in the flow of work — fully managed OAuth; Claude hands you an auth link and picks up where it left off once you approve. Connections persist across sessions.

Install

In Claude Code:

/plugin marketplace add ComposioHQ/composio-plugin-cc
/plugin install composio@composio

Then ask Claude to do something — for example, "Star composiohq/composio on GitHub." On first use, Claude sets up everything it needs: it offers to install the Composio CLI if it's missing (behind the normal permission prompt), signs you in with composio login, and hands you an OAuth link to connect the app. Approve it in your browser and Claude runs the action.

Prefer to set things up ahead of time?

curl -fsSL https://composio.dev/install | bash
composio login

Logging in also installs the composio-cli skill, which gives Claude detailed usage guidance.

Team setup

Add this to .claude/settings.json in a project to auto-enable the plugin for teammates:

{
  "extraKnownMarketplaces": {
    "composio": {
      "source": { "source": "github", "repo": "ComposioHQ/composio-plugin-cc" }
    }
  },
  "enabledPlugins": {
    "composio@composio": true
  }
}

Examples

Naming the app explicitly keeps tool search scoped and the run reliable.

Single app:

What's on my Google Calendar for tomorrow? Add an event for lunch at 12PM.

Connect an app ahead of time:

/composio-connect linear

Cross-app workflow (reads feed the write):

Take the latest merged PR in acme/app, open a Linear issue summarizing it,
and post the issue link to #eng in Slack.

Parallel reads, then summarize:

In parallel, fetch my last 10 Gmail emails, my open Linear issues, and today's
Google Calendar events. Redact personal info, then give me a concise summary.

What's inside

Three small components; all tool logic lives in the composio CLI:

Because capabilities ship in the CLI, composio upgrade keeps them current — no plugin update needed.
