WHAT IT DOES

What drive_folder_restore does on TrekMail MCP Server

WHY IT NEEDS A POLICY

Why drive_folder_restore needs a policy

While the tool name contains 'restore', restoration itself is a Write operation (modifying state to recover deleted content) rather than Destructive. However, the blast radius is high because: (1) it operates on potentially large folder structures and all contained data, (2) if misused by an agent, it could restore unintended sensitive or quarantined content, (3) it affects email infrastructure persistence.

From the tool's definition Tool name 'drive_folder_restore' and description 'Restore a trashed folder + everything that was deleted in the same operation' indicate a restoration/recovery operation that reverses a destructive action.
