drive_folder_create · Google Workspace MCP: Risk & Policy

WHAT IT DOES

What drive_folder_create does on Google Workspace

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

WHY IT NEEDS A POLICY

Why drive_folder_create needs a policy

Creating a folder is a reversible write operation that modifies data by adding a new container to the file system. It does not execute arbitrary code, delete data, or affect financial systems. The blast radius is low since folder creation is easily undone by deletion and has minimal impact on system state.

From the tool's definition Tool description states 'Create a new folder.' The name 'drive_folder_create' and description confirm this performs a create operation on Google Drive.
