Google Ads inside Cursor

Marketing sites and ad campaigns are built by the same people more often than ever. With PaidHelm in Cursor, the agent that edits your landing page can also read the search terms that land on it and write ads that match the copy it just shipped.

Setup

Create or edit .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "paidhelm": {
      "url": "https://mcp.paidhelm.com/googleads/mcp"
    }
  }
}

Open Settings → MCP; PaidHelm appears with a Needs login state. Click it, finish Google's consent screen, and the tool list loads.

Using it

In Agent mode, mention what you want; Cursor picks the tools.

Rules file

Add a .cursor/rules/google-ads.mdc with your guardrails (accounts, budget limits, "paused by default") so every agent run follows them.

Index the docs

Cursor can index paidhelm.com/docs via @Docs → Add new doc. The agent then has the full tool catalog and GAQL reference at hand.

Troubleshooting

• Server shows red: check JSON syntax and that the URL ends with /googleads/mcp.
• OAuth loop: Cursor needs to accept the callback; make sure no extension blocks localhost redirects.
