Permanently delete a movie or episode from the Plex library by its ratingKey. Get the ratingKey from plex_search.
AI agents call plex_delete_media to permanently remove resources in Homelab — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes media content from a Plex library. Once deleted, the data cannot be recovered through normal means. This is a destructive operation that cannot be undone, making it a Destructive category risk. Severity is high because an AI agent with misaligned goals could systematically delete a user's entire media library, causing significant loss of content and personal media collection value.
From the tool's definition Tool name explicitly states 'delete' and description confirms 'Permanently delete a movie or episode from the Plex library'. The term 'permanently' indicates irreversible data loss.
