`range`	string	Yes	Range to update (e.g., 'Sheet1!A1:C10')

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs updateGoogleSheet 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 updateGoogleSheet, this is the rule to start with:

updateGoogleSheet Rate-limited

updateGoogleSheet 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.
