Zapier MCP
Productivity & Comms
Connects Claude to thousands of apps you already use, through Zapier.

One connector that lets Claude act in 1,500+ apps, from Gmail to your CRM.
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.
Open your terminal in the project folder and run:
claude mcp add --transport http composio https://connect.composio.dev/mcpYou'll be asked to sign in or paste an API key the first time you use it.
Anyone who wants Claude working across lots of business apps without setting up a connector for each one.
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.
