sheets_protect · Gworkspace MCP: Risk & Policy

WHAT IT DOES

What sheets_protect does on Gworkspace

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

WHY IT NEEDS A POLICY

Why sheets_protect needs a policy

Protection settings in Google Sheets are metadata changes that modify sheet properties and access controls. This is a Write operation because it creates or modifies configuration reversibly. While it affects permissions, it does not destroy data (not Destructive), execute code (not Execute), or move money (not Financial).

From the tool's definition Tool name 'sheets_protect' and description 'Protect a sheet or range' indicates modification of sheet properties and access controls. This is a reversible operation that changes data permissions rather than the data itself.

Verdict

sheets_protect Rate-limited

sheets_protect stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
