Permanently deletes an email
AI agents call delete_email to permanently remove resources in Gmail AutoAuth MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes email data that cannot be recovered. While the blast radius is typically limited to a single email or user's mailbox (not systemic), permanent deletion of communications is a high-severity destructive action. It exceeds Write (which is reversible) and qualifies as Destructive per the classification rules.
From the tool's definition Permanently deletes an email - the word 'Permanently' and 'deletes' indicate irreversible data destruction.
