The steps below are for organization admins on Team / Enterprise plans. On Pro / Max plans, you can add the connector for yourself from Settings → Connectors with the same steps.

Account menu
  1. Select Connectors in the sidebar

2. Add a custom connector

  1. Select Custom → Web from the Add menu
Custom option in the Add menu

    • Name: Arlet
    • Remote MCP server URL: https://mcp.arlet.dev/mcp/
Add custom connector example
  1. The authentication settings are auto-detected from Arlet’s server, so keep the defaults (Authentication: Always required, OAuth client: No client ID — register one automatically) and click Add
Authentication settings confirmation
Claude registers an OAuth client automatically (Dynamic Client Registration), so there is no need to enter a Client ID / Client Secret manually.

​
3. Authentication

Each user is asked to authenticate the first time they use the Arlet connector. Sign in with Google and complete the OAuth flow.
