Composio MCP

One connector that lets Claude act in 1,500+ apps, from Gmail to your CRM.

What is it?

Composio puts more than 1,500 apps behind one connector. Instead of adding a separate server for Gmail, Slack, HubSpot and Notion, you add Composio once, sign in to each app when Claude first needs it, and Claude picks the right action itself.

In Claude on the web or desktop, add it under Settings, Connectors, Add custom connector with the URL https://connect.composio.dev/mcp. In Claude Code, run the command below and sign in through /mcp. It works the same way in ChatGPT, Cursor and other MCP clients.

Compared with Zapier MCP, calls are far cheaper: the free plan covers 100,000 a month, where Zapier counts two tasks per call. The trade-off is a more developer-flavoured dashboard.

What Claude can do once it's connected

  • Send, search and reply to email in Gmail or Outlook
  • Update deals and contacts in HubSpot or Salesforce
  • Post and read messages in Slack
  • Create pages, issues and tasks in Notion, GitHub or Linear
  • Find the right action across 1,500+ apps when you ask in plain English

Install in Claude Code

Open your terminal in the project folder and run:

Command
claude mcp add --transport http composio https://connect.composio.dev/mcp

You'll be asked to sign in or paste an API key the first time you use it.

Who it's for

Anyone who wants Claude working across lots of business apps without setting up a connector for each one.

Best for

  • Many apps through one connector
  • Email and CRM actions
  • Apps with no official MCP

Why it made the list

It covers more apps than any other single connector, and the free plan is big enough that most people never pay.
