Why google_ads_ads_create_display needs a policy

This tool creates new ad assets within Google Ads campaigns, which is a reversible write operation. It does not delete data (not Destructive), does not move money directly (not Financial—though ad creation can trigger spend, the tool itself only creates the ad structure), and does not execute arbitrary code (not Execute).

From the tool's definition Tool name explicitly contains 'create' and description states 'Creates a Responsive Display Ad (RDA) in a DISPLAY campaign'. This is a data creation operation that modifies advertising accounts.

POLICY

How to control google_ads_ads_create_display

PolicyLayer is an MCP gateway — it sits between your AI agents and Mureo, and nothing reaches the server without passing your rules. This is the rule we recommend for google_ads_ads_create_display:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "google_ads_ads_create_display": {
      "limits": [
        {
          "counter": "google_ads_ads_create_display_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

google_ads_ads_create_display stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Mureo — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
