Performs container operations: get, list, create, update, delete.
AI agents call gtm_container 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.
Although this tool supports Read (get, list), Write (create, update), and Destructive (delete) operations, the presence of delete capability—which irreversibly removes GTM containers and their configurations—makes it Destructive. A container is a significant resource in GTM that aggregates tags, triggers, and variables. Deleting a container cannot be undone and would disrupt tracking/analytics infrastructure.
From the tool's definition Tool description explicitly states it 'Performs container operations: get, list, create, update, delete.' The delete operation is irreversible.
Attacks that exploit this kind of access
Performs container operations: get, list, create, update, delete. It is categorised as a Destructive tool in the Google Tag Manager MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Google Tag Manager MCP Server MCP server in PolicyLayer and add a rule for gtm_container: 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_container 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_container 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.
Set action: deny in the PolicyLayer policy for gtm_container. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
gtm_container is provided by the Google Tag Manager MCP Server MCP server (metkamedia/gtm-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
