Soft-delete folder + entire subtree (cascade). Active share-links on contained files are revoked.
AI agents call drive_folder_trash to permanently remove resources in TrekMail MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Although described as 'soft-delete,' the tool removes an entire folder hierarchy and revokes all active share-links on contained files. This is an irreversible data deletion operation affecting potentially many files and their sharing permissions.
From the tool's definition Tool description explicitly states "Soft-delete folder + entire subtree (cascade)" which deletes a folder and all contained items irreversibly. Additionally, "Active share-links on contained files are revoked," indicating permanent removal of access.
