THE RISK

Why get_creative_preview_url needs a policy

The tool appears to retrieve a preview URL for a creative asset, which is a non-destructive query operation. Even though the description is missing (lowering confidence slightly), the name unambiguously suggests a GET/retrieval action. No modifications, deletions, code execution, or financial transactions are implied. Blast radius is minimal—an agent requesting a preview URL causes no harm.

From the tool's definition Tool name 'get_creative_preview_url' indicates retrieval of a preview URL—a read-only operation that queries/fetches data without modifying state. Description is empty, but the name strongly suggests data retrieval.

POLICY

How to control get_creative_preview_url

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_creative_preview_url": {}
  }
}

get_creative_preview_url is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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