Performs all container version header operations: list, latest. The
AI agents call gtm_version_header to retrieve information from Unboundai Gtm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The gtm_version_header tool only retrieves version header information (list and latest operations). These are non-destructive, informational queries. There is no capability to modify, delete, or execute code. The blast radius of misuse is minimal—an agent could at worst retrieve metadata about GTM container versions.
From the tool's definition Tool description states 'Performs all container version header operations: list, latest' — both list and latest are read-only query operations with no side effects.
Attacks that exploit this kind of access
Performs all container version header operations: list, latest. The. It is categorised as a Read tool in the Unboundai Gtm MCP Server, which means it retrieves data without modifying state.
Register the Unboundai Gtm MCP server in PolicyLayer and add a rule for gtm_version_header: 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 Unboundai Gtm. Nothing to install.
gtm_version_header 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_version_header 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_version_header. 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_version_header is provided by the Unboundai Gtm MCP server (tijevlam/unboundai-google-tag-manager-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
