Yes, you can. However, Claude’s mobile app does not have a screen for adding connectors, so the setup itself has to be done once in a browser.

​
How to connect

  1. Open Claude on your phone’s browser (Safari, Chrome, and so on) and log in.
  2. Go to [Customize(사용자 지정)] → [Connectors(커넥터)] → [Add(추가)] (claude.ai/settings/connectors).
  3. In the [Add custom connector(커스텀 커넥터 추가)] dialog, enter Carat for [Name(이름)] and https://mcp.carat.im/mcp for [Remote MCP server URL(원격 MCP 서버 URL)], then save.
  4. Log in with your Carat account when the Carat login window appears and allow access.
Once that is done, Carat’s tools appear in the Claude mobile app as well. The connector is stored on your account, so there is nothing to set up again in the app.
Sometimes tapping the link opens the Claude app instead and never reaches the add-connector screen. In that case, type the address into your browser directly, or connect once on a computer — it will then work on your phone too.

Connected, but the app still does not show the tools

Open a new chat in the app and check that Carat is switched on under [Connectors(커넥터)] in the message box. The full order is in Carat’s tools do not show up in Claude.
