rename_doc · Google Sheets MCP: Risk & Policy

WHAT IT DOES

What rename_doc does on Google Sheets MCP

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

WHY IT NEEDS A POLICY

Why rename_doc needs a policy

Renaming a spreadsheet modifies its metadata but is reversible and does not execute code, delete data, or move money. It fits the Write category as it creates or modifies data reversibly. Severity is medium because widespread renaming of shared documents could cause confusion and workflow disruption, but the operation itself is easily undone.

From the tool's definition Tool name 'rename_doc' and description 'Rename the Google Spreadsheet' indicate modification of metadata. Renaming is a reversible write operation that changes document properties without deleting or executing arbitrary code.
