Connect Google Search Console and GA4 to Gemini CLI

Steps

1. Gemini CLI: run gemini mcp add --transport http rankgaroo https://mcp.rankgaroo.com/mcp. Scope is project by default. Use -s to change it.

2. Or add this to settings.json:

   Config (JSON)Copy

   {
     "mcpServers": {
       "rankgaroo": {
         "httpUrl": "https://mcp.rankgaroo.com/mcp"
       }
     }
   }

3. Inside the CLI, run /mcp auth to list servers that need sign-in, then run /mcp auth rankgaroo. Finish in the browser.

4. Run /mcp list to check the connection. It shows connection errors that are otherwise hidden.

5. Antigravity CLI: edit ~/.gemini/config/mcp_config.json (global) or <workspace>/.agents/mcp_config.json and add: {"mcpServers":{"rankgaroo":{"serverUrl":"https://mcp.rankgaroo.com/mcp"}}}. Type /mcp in the prompt panel to open the MCP Manager Overlay.

6. Antigravity IDE: open Agent settings (Cmd or Ctrl + comma), go to the Customizations tab, click Authenticate next to rankgaroo, sign in, copy the authorization code, paste it in the panel and click Submit.

Signing in with Google

In Gemini CLI, /mcp auth rankgaroo opens your browser on the Rankgaroo consent page, which names the app. Click Continue to Google, then review Google's read-only Search Console and Analytics request. You can untick either. In the Antigravity IDE you copy an authorization code from the browser and paste it back into the panel.

What you need

• Gemini CLI is still served for Gemini Code Assist Standard or Enterprise licenses, and for paid Gemini API keys or Gemini Enterprise Agent Platform keys.
• Unpaid-tier and Google One users moved to Antigravity CLI on June 18, 2026. Use the Antigravity steps below if that is you.
• A browser on the same machine. Sign-in fails over headless or SSH sessions.

Good to know

• The Gemini CLI callback is http://localhost:<random-port>/oauth/callback. You can fix the port with redirectUri.
• Avoid underscores in the server name. Use rankgaroo, not a name with underscores.
• Gemini CLI needs a local browser for sign-in, so it fails over headless or SSH sessions.
• Antigravity accepts serverUrl or url in its config, but not httpUrl, and it does not accept SSE. Its docs name no add command.
• How sign-in starts in the Antigravity CLI, as opposed to the IDE, is not documented.
• Gemini CLI's docs do not mention Client ID Metadata Documents. It uses Dynamic Client Registration, which Rankgaroo supports.

First questions to try

• List my Search Console properties and GA4 properties.

  Copy

• Which pages lost the most clicks in Search Console over the last 28 days?

  Copy

• Which channels drove the most GA4 sessions last month, and how did organic search compare?
