Why deleteSheet is rated Critical
This tool permanently removes a sheet and all its contents from a Google Sheet, which cannot be undone programmatically. Deletion is irreversible and represents data loss. This is the most severe category applicable.
From the tool's definition Tool name 'deleteSheet' combined with description 'Delete a sheet/tab by sheetId' explicitly performs irreversible deletion of data structures.
Attacks that exploit this kind of access
The rule that runs deleteSheet safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Google Drive, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For deleteSheet, this is the rule to start with:
deleteSheet is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Google Drive, apply this rule, and every deleteSheet call is checked against it from then on.
