Why list_script_includes needs a policy

This tool retrieves or queries script includes from ServiceNow without creating, modifying, deleting, or executing code. It simply returns a filtered list of existing script include records. The capability to filter by name or API name further confirms this is a non-destructive information retrieval operation with no blast radius beyond data exposure.

From the tool's definition Tool name 'list_script_includes' and description 'Lists Script Includes, with options to filter by name or API name' indicate a retrieval operation with no side effects. The verb 'list' and filtering parameters are characteristic of read-only query operations.

POLICY

How to control list_script_includes

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

policy.json

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

list_script_includes 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 Snow — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
