Why create_script_project_tool needs a policy

Creating a new script project is a write operation that modifies the user's Google Apps environment by adding a new resource. It is reversible (deletion possible) and has moderate blast radius—an agent could create many projects or ones with unintended names/configurations—but lacks the finality of destructive operations.

From the tool's definition Tool name 'create_script_project_tool' indicates creation of a new Apps Script project. Server description states the tool enables users to 'create, manage, and execute Google Apps Script projects'. The 'create' action is reversible (projects can be deleted).

POLICY

How to control create_script_project_tool

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 create_script_project_tool:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_script_project_tool": {
      "limits": [
        {
          "counter": "create_script_project_tool_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_script_project_tool 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.

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.
