AI agents call gtm_zone to permanently remove resources in Google Tag Manager MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool supports 'remove' (irreversible deletion of GTM zones) and 'revert' (undoes unpublished changes, which can also be destructive). Since the most severe applicable category must be chosen, and 'remove' constitutes irreversible deletion, this is classified as Destructive. Misuse could delete GTM zones affecting tracking and analytics across web properties.

Documented attack patterns abuse exactly the kind of access gtm_zone gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Google Tag Manager MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for gtm_zone:
{
"version": "1",
"default": "deny",
"hide": [
"gtm_zone"
]
}gtm_zone disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Register the Google Tag Manager MCP Server MCP server in PolicyLayer and add a rule for gtm_zone: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Google Tag Manager MCP Server. Nothing to install.
gtm_zone is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the gtm_zone rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
