THE RISK

Low Risk

Why find_atf_tests needs a policy

This is a read-only operation that searches for existing ATF tests. It retrieves information about tests but does not execute them, modify them, or cause side effects. The search/find operation is characteristic of Read category tools. Severity is low because the worst-case misuse would be information disclosure about available tests, which has minimal impact.

From the tool's definition The tool name 'find_atf_tests' and description 'Search for ATF (Automated Test Framework) tests on a ServiceNow instance' indicate a query/search operation that retrieves test metadata without modifying or executing anything.

POLICY

How to control find_atf_tests

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

policy.json

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

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