Composio

Composio gives AI assistants and agents secure access to more than 1,500 apps, so tools like Claude, ChatGPT, Cursor, and custom agents can take actions across the software you already use instead of acting as another standalone chatbot.

Key Features

• Broad app connections — Connect Gmail, Google Calendar, Slack, Notion, GitHub, Google Drive, HubSpot, Salesforce, Instagram, and many others, with support for multiple accounts on the same app and connections reusable across different AI assistants.
• Per-action permissions — You approve access on each app's own sign-in page, choose which actions the AI may take, require approval for some, and remove a connection at any time. Passwords and tokens are kept by Composio, not exposed to the AI.
• Tested skills for recurring work — Skills package proven steps for a job, such as preparing a meeting brief, so the AI knows what to check and what to avoid.
• Heavy-work computer — For large tasks, the AI runs code in a private workspace and returns just the answer, as in reconciling thousands of payouts against a ledger.
• Instant tools — 1,500+ tools for search, enrichment, transcription, and more, available pay-per-use without creating accounts.
• Action log — Every action is recorded with the app involved and what needed your approval, and prompt injections hidden in emails or pages are blocked before the AI reads them.

Typical Use Cases

• Meeting preparation: Ask your assistant to prepare for a 10am call; a loaded skill researches the company and attendees, reviews recent threads, and produces a one-page brief with talking points.
• Finance reconciliation: An agent downloads Stripe payouts, matches them against the Xero ledger, and flags the payouts that need review.
• Everyday app actions: Instruct your AI to update a CRM, file issues, send emails, or post to Slack through connected accounts.
• Agent development: Developers building their own agents use Composio as an integration layer for authentication, tool access, and actions, installing packages such as @composio/core or @composio/openai.

How It Works

1. Connect Composio to the AI you already use — one-click installs for ChatGPT/Codex and Grok Bot, a Claude connector, a Claude Code plugin, a single MCP URL for Cursor, or a prompt for Hermes.
2. Connect the apps you want, usually in a couple of clicks, or ask your AI to generate the connection link.
3. Set permissions per app and per action, optionally requiring approval.
4. Ask your agent to do something; it searches for the right tool, runs the action, and records it in the trace.

Who It's For

Composio suits people who want their existing AI assistant to act inside their apps without coding, as well as developers who need a ready-made integration layer for their own agents. Teams that handle multi-app or high-volume tasks benefit from tested skills, the private code workspace, and the recorded action log.

Composio is most useful for anyone who wants an AI assistant to take real, permission-controlled actions across many apps rather than only answer questions.
