Why list_script_processes_tool needs a policy

This tool queries and returns metadata about past script executions without altering, executing, or deleting any scripts or data. It is a passive audit/monitoring function analogous to checking logs or status. The blast radius of misuse is minimal: an attacker might learn execution history but cannot execute new code, modify scripts, or destroy data.

From the tool's definition Tool name contains 'list' and description states 'List recent execution processes' — a retrieval operation with no modification or side effects.

POLICY

How to control list_script_processes_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 list_script_processes_tool:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_script_processes_tool": {}
  }
}

list_script_processes_tool is read-only, so it stays allowed — but 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.
