Why google_gmail_delete_email needs a policy

Deleting emails is a destructive action that cannot be trivially undone without backup restoration or service recovery mechanisms. An AI agent with access to this tool could maliciously delete important emails, conversations, or evidence. While some email systems allow recovery from trash for a limited time, the primary intent and effect is removal.

From the tool's definition Tool name and description explicitly state 'Delete or trash an email' — this removes email data irreversibly or moves it to a recoverable but separate state.

POLICY

How to control google_gmail_delete_email

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

policy.json

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

google_gmail_delete_email 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 Google MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
