WHAT IT DOES

What mittwald_database_mysql_user_delete does on Mittwald MCP Server

AI agents call mittwald_database_mysql_user_delete to permanently remove resources in Mittwald MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why mittwald_database_mysql_user_delete is rated Critical

The tool permanently removes a MySQL user, which is an irreversible operation that cannot be recovered automatically. While not a data deletion itself, account deletion has blast radius: an AI agent misusing this could lock legitimate users out of databases or cause authentication failures in production systems. This is more severe than Write (reversible modifications) and qualifies as Destructive.

From the tool's definition Tool name contains 'delete' and description states 'Delete an existing MySQL user' — this irreversibly removes a user account and cannot be undone without manual restoration.
