Why generate_trigger_code needs a policy

The description is empty, so the exact behavior cannot be determined. The name suggests it generates code for triggers (possibly Write or Execute), but 'generate' could mean it only produces code text without executing it (Read/Write). Given the server context of Apps Script management, trigger code generation likely creates or writes script content, but without confirmation, confidence is low.

From the tool's definition Tool name: 'generate_trigger_code'; description is empty or uninformative.

POLICY

How to control generate_trigger_code

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_trigger_code": {
      "limits": [
        {
          "counter": "generate_trigger_code_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

generate_trigger_code gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register Apps Script MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Enforce policy on every Apps Script MCP tool call.

Start from Apps Script MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
