List all permissions (sharing) on a file or folder.
AI agents call gdrive_list_permissions to retrieve information from Mcp Google Gdrive without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves permission/sharing information about files or folders. It has no side effects—it does not modify, delete, or execute anything. Reading permission metadata is a safe read operation. The only minor consideration is that permission lists may contain sensitive information about who has access, but the operation itself is read-only and non-destructive.
From the tool's definition Tool name is 'gdrive_list_permissions' and description states 'List all permissions (sharing) on a file or folder.' The verb 'list' is a read operation that retrieves metadata without modification.
