copy_worksheet · Google Connections MCP: Risk & Policy

WHAT IT DOES

What copy_worksheet does on Google Connections

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

WHY IT NEEDS A POLICY

Why copy_worksheet needs a policy

Copying a worksheet creates new data structures and content in the destination location. While reversible (the copy can be deleted), it represents data creation/modification rather than mere retrieval (Read). It does not execute arbitrary code (Execute), permanently destroy data (Destructive), or move money (Financial).

From the tool's definition Tool description states it 'Copy[ies] a worksheet' which creates a new copy of worksheet data in the same or different spreadsheet. This is a reversible modification operation.
