WHAT IT DOES

What deploy_gas_webapp does on Google Apps Script MCP Server

AI agents invoke deploy_gas_webapp to trigger actions in Google Apps Script 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 deploy_gas_webapp needs a policy

Deploying a web app executes code in a production environment with externally-facing effects. While not immediately destructive (the deployment itself is reversible), it activates code execution on Google's infrastructure and makes it publicly accessible. This is Execute rather than Write because deployment triggers execution in a production context, not merely data modification.

From the tool's definition Tool name 'deploy_gas_webapp' and description 'Google Apps ScriptをWebアプリとしてデプロイします' (Deploy Google Apps Script as a web app) indicate deployment of executable code to a live environment.
