Connect ROASaurus to Grok

Set it up

1. Create a named API key with the mcp scope under Store settings › API & data.
2. In a request to the xAI API, add a remote MCP tool with the server URL below and the key as its authorization.
3. Grok calls the ROASaurus tools while it answers.

{
  "tools": [
    {
      "type": "mcp",
      "server_url": "https://app.roasaurus.com/mcp?mode=search",
      "server_label": "roasaurus",
      "authorization": "rsk_…"
    }
  ]
}

ROASaurus is not in the Grok marketplace yet; until it is, the xAI API is the way to connect.

Then ask

• Which campaigns made a profit last month after product costs and fees?
• Compare Meta and Google Ads ROAS this week with last week and explain the difference.
• Find ad sets that spend without sales and propose to pause them.

Changes are proposals in the Actions inbox unless you allowed actions:apply. Read more on the MCP server page.
