THE RISK

Critical Risk

Why delete_event_tool needs a policy

Deleting a calendar event destroys data that cannot be recovered through the tool itself. Although severity is not critical (calendar events are not financial or life-critical), the irreversible nature of deletion, combined with potential calendar disruption, warrants high severity. Confidence is high because the intent is unambiguous.

From the tool's definition Tool name contains 'delete' and description states 'Delete a calendar event' — this irreversibly removes calendar data.

POLICY

How to control delete_event_tool

PolicyLayer is an MCP gateway — it sits between your AI agents and Apps Script MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_event_tool:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_event_tool"
  ]
}

delete_event_tool disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Apps Script MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
