gdrive_copy_file · Mcp Google Gdrive MCP: Risk & Policy

WHAT IT DOES

What gdrive_copy_file does on Mcp Google Gdrive

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

WHY IT NEEDS A POLICY

Why gdrive_copy_file needs a policy

Copying a file creates new data in Google Drive, which is a reversible write operation. While it does not delete data (ruling out Destructive), it does create or modify the drive state. The severity is medium because unchecked file copying could lead to storage exhaustion, unintended data duplication, or confusion in a user's drive structure, but the operation is reversible via deletion.

From the tool's definition Tool description states 'Copy a file, optionally to a different folder with a new name.' This creates a new file object by duplicating an existing one, modifying the filesystem state. The term 'copy' is a write operation that creates new data.
