WHAT IT DOES

What delete-email does on MCP Google Workspace

AI agents call delete-email to permanently remove resources in MCP Google Workspace, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete-email is rated Critical

This tool performs irreversible deletion of email messages. Even though it defaults to trash (recoverable), it provides a permanent=true option that cannot be undone, making it Destructive rather than Write. The high severity reflects that emails often contain sensitive personal, financial, or business information, and permanent deletion would result in complete data loss with no recovery path.

From the tool's definition Tool description explicitly states 'delete permanently' and 'unrecoverable deletion' with permanent=true parameter. The tool can irreversibly remove email data from Gmail.
