Parameters from the server's own tool schema.
The tool performs an irreversible delete operation on a database key. This is a destructive action that cannot be undone. While the blast radius is limited to a single key rather than an entire database, unauthorized deletion of data in a production Redis instance could cause application failures, data loss, and service disruption.
