The rule that runs batchUpdateGoogleSheetValues safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Google Drive, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For batchUpdateGoogleSheetValues, this is the rule to start with:
batchUpdateGoogleSheetValues 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Google Drive, apply this rule, and every batchUpdateGoogleSheetValues call is checked against it from then on.
