How to control sheets_duplicate_sheet

PolicyLayer is an MCP gateway — it sits between your AI agents and Google Workspace, and nothing reaches the server without passing your rules. This is the rule we recommend for sheets_duplicate_sheet:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "sheets_duplicate_sheet": {
      "limits": [
        {
          "counter": "sheets_duplicate_sheet_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

sheets_duplicate_sheet 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.
