WHAT IT DOES

What publish_gtm_container does on Google Tag Manager MCP Server

AI agents invoke publish_gtm_container to trigger actions in Google Tag Manager MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why publish_gtm_container needs a policy

Publishing a GTM container version pushes tag/tracking configuration changes live to a production website, affecting all visitors. This is an external operation with real-world impact (analytics and pixel tags go live), making it Execute. While it may be partially reversible by publishing a previous version, the act of publishing itself is an active deployment trigger.

From the tool's definition 'Publish GTM container version (실제 배포)' — 'publish' and '실제 배포' (meaning 'actual deployment') indicate this triggers an external publishing/deployment operation
