AI Clients

Grok & Grok Build

Grok’s chat app and its CLI, Grok Build, both speak remote MCP with OAuth, so MCP Ads connects the same way it connects to Claude. Grok Bot, the autonomous agent, is a separate client with its own page.

Add the server

Pick the surface you use. All three take the same URL.

On grok.com open Connectors from the + button, choose New Connector, then Custom. Paste the URL and finish the sign-in when it opens. On mobile it is under Settings → Connectors.

Custom connector

Authorise

The chat app and Grok Build open a browser window for the MCP Ads sign-in on the first call. Approve it once; the grant persists and refreshes on its own.

Where this helps

Asking about spend and results across every platform in one chat, without opening a dashboard
Building a campaign in conversation and reviewing the exact changes before they go live
Grok Build: pulling live ad metrics into a script or a report from the terminal

Common questions

Does the Grok chat app need a paid plan for custom connectors?

xAI’s documentation covers Grok Business and Enterprise; consumer reports put custom connectors behind SuperGrok or X Premium+. Confirm on x.ai before assuming a free account can add one.

Is there a one-click install like Claude’s?

Not for Grok. There is no query-parameter deep link into the connector form, so the URL is pasted. Grok Build’s single command is the closest equivalent.

Why does the API example use a key instead of OAuth?

The xAI API’s mcp tool only carries an authorization value and headers; there is no place for an authorization-code flow to run. An MCP Ads API key fills that field. Create one under Manage → Connect MCP.
