List contents of a Google Drive folder
AI agents call gdrive_folder_list to retrieve information from GDrive MCP Server 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 folder contents without side effects. It is a standard read operation analogous to 'list' or 'get'. No data is created, modified, deleted, or executed. The blast radius is limited to information disclosure of folder structure and file metadata that the authenticated user already has access to.
From the tool's definition Tool name 'gdrive_folder_list' and description 'List contents of a Google Drive folder' indicate a retrieval operation with no modification or deletion of data.
