AI agents call gtm_get_live_version to retrieve information from Gtm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves the current published version of a GTM container. It performs a read-only operation that does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal—an agent could only access existing GTM configuration information without making changes. Confidence is high because the description is explicit about the retrieval nature of the operation.
From the tool's definition Tool name 'gtm_get_live_version' and description 'Get the currently published (live) version of a container' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Get the currently published (live) version of a container. It is categorised as a Read tool in the Gtm MCP Server, which means it retrieves data without modifying state.
Register the Gtm MCP server in PolicyLayer and add a rule for gtm_get_live_version: 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 Gtm. Nothing to install.
gtm_get_live_version is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the gtm_get_live_version 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_get_live_version. 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_get_live_version is provided by the Gtm MCP server (tijevlam/gtm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
