Why gmail_deleteEmail needs a policy

Email deletion is a destructive operation that removes user data. Even though Gmail's trash may retain the email temporarily before permanent deletion, the immediate effect is to remove the email from the user's active mailbox. An AI agent with this capability could maliciously delete important messages, causing data loss.

From the tool's definition Tool name 'gmail_deleteEmail' and description 'Delete an email (moves to trash by default)' explicitly perform deletion of email messages. The phrase 'delete' and 'moves to trash' indicate irreversible removal of data from the user's inbox.

POLICY

How to control gmail_deleteEmail

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

policy.json

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

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