What empty_trash does on AIquila — Nextcloud MCP Server
AI agents call empty_trash to permanently remove resources in AIquila — Nextcloud MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why empty_trash is rated Critical
This tool irreversibly destroys data at scale (all trash contents) without selective recovery options. While the blast radius is somewhat limited by only affecting trashed files, the permanent and unrecoverable nature of the operation makes it Destructive rather than Write. Severity is high due to potential data loss, though not critical since it only affects already-deleted items rather than live data.
From the tool's definition 'Permanently delete all files in the trash (cannot be undone)' explicitly states irreversible deletion with no undo capability.
