Delete an SFTP user.
AI agents call mittwald_sftp_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.
Deletion of user accounts is an irreversible action that cannot be undone without manual intervention (account recreation). This fits the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.' The impact is significant but scoped to a single user account rather than bulk data or infrastructure, making it 'high' rather than 'critical' severity.
From the tool's definition Tool name contains 'delete' and description states 'Delete an SFTP user' — this irreversibly removes an SFTP user account and all associated access credentials.
