If the connector is set up but Claude cannot find Carat’s tools, check the following in order. In most cases it is because you are in a chat that was already open or because the connector is switched off.

​
1. Open a new chat

Carat’s tools are not picked up in chats you opened before adding the connector. Start a new chat after connecting.

​
2. Check that Carat is on under [Connectors(커넥터)]

Open the [Connectors(커넥터)] menu in Claude’s message box and confirm Carat is switched on. Even with the connector added, the tools will not appear if it is off for that chat.

​
3. Turn the connector off and reconnect

If it is on and the tools still do not appear, go to [Customize(사용자 지정)] → [Connectors(커넥터)] in Claude and turn Carat off, then connect again. When the Carat login window appears during reconnection, log in with your Carat account and allow access.

​
4. Set tool permissions to [Always allow(항상 허용)] for regular use

If Claude asks for permission every time you make a request, set the permission to [Always allow(항상 허용)] and it will stop asking on later requests.
The connection fails if the connector is registered with an old address. The current address is https://mcp.carat.im/mcp. If you registered a different one, delete the connector and add it again with this address.

​
If the tools still do not appear

  • Check that you are logged in to your Carat account. The connector requires Carat account authentication, and tool calls fail once that authentication expires.
  • Refresh the tool list. An older cached tool list can leave you with the wrong set. If your environment cannot refresh it, connect the connector again.
  • If none of the above resolves it, use [Contact(문의하기)] in the Carat app or website and tell us which Claude environment you are using (web, app, or Claude Code) along with a screenshot.
Seeing a tool is not the same as a task running to completion. Free and paid plans both get the same tools, but each task is still subject to your account permissions and credit conditions — a request will not go through if your credits fall short (see Can I use MCP on the Free plan?).
