WHAT IT DOES

What restore_properties does on Google Apps Script MCP Server

AI agents use restore_properties to create or update resources in Google Apps Script MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Apps Script MCP Server environment.

WHY IT NEEDS A POLICY

Why restore_properties needs a policy

This tool restores (modifies) script properties from a backup, making it a Write operation rather than Read (it changes state) or Destructive (restoration is reversible and typically intended to revert to a previous known state). Severity is medium because improper restoration could break scripts or expose sensitive data, but the operation itself can be reversed by taking another backup or manual correction.

From the tool's definition Tool name 'restore_properties' and description '🔄 バックアップからスクリプトプロパティを復元します' (Restore script properties from backup) indicate it modifies/restores properties. The sibling tool 'backup_properties' confirms this is part of a backup/restore system.
