AI agents call deleteSheet to permanently remove resources in Google Drive MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
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.
Documented attack patterns abuse exactly the kind of access deleteSheet gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Google Drive MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for deleteSheet:
{
"version": "1",
"default": "deny",
"hide": [
"deleteSheet"
]
}deleteSheet disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a sheet/tab by sheetId. It is categorised as a Destructive tool in the Google Drive MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Google Drive MCP Server MCP server in PolicyLayer and add a rule for deleteSheet: 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 Google Drive MCP Server. Nothing to install.
deleteSheet is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the deleteSheet 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 deleteSheet. 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.
deleteSheet is provided by the Google Drive MCP Server MCP server (piotr-agier/google-drive-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
