renameFile · Google Workspace MCP Server MCP: Risk & Policy

WHAT IT DOES

What renameFile does on Google Workspace MCP Server

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

WHY IT NEEDS A POLICY

Why renameFile needs a policy

Renaming a file is a reversible write operation that changes a property of an existing resource without deleting it or executing arbitrary code. While it could cause confusion if misused (e.g., renaming critical files to obscure names), the action is not destructive and can be undone by renaming again.

From the tool's definition Tool name 'renameFile' and description 'Renames a file or folder in Google Drive' indicate the tool modifies metadata of existing resources.
