Execute a ServiceNow ATF test suite and wait for all tests to complete.
AI agents invoke run_atf_test_suite to trigger actions in Now Sdk Ext. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This is an Execute tool because it runs automated test suites whose side effects depend on the test suite arguments and ServiceNow instance configuration. While tests are typically designed to be repeatable, they can have lasting effects on the ServiceNow instance (data creation, configuration changes, etc.).
From the tool's definition Tool enables 'Execute a ServiceNow ATF test suite' which runs automated tests whose effects depend on test definitions and ServiceNow instance state.
Documented attack patterns abuse exactly the kind of access run_atf_test_suite gives an agent:
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 run_atf_test_suite:
{
"version": "1",
"default": "deny",
"tools": {
"run_atf_test_suite": {
"limits": [
{
"counter": "run_atf_test_suite_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} run_atf_test_suite stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Execute a ServiceNow ATF test suite and wait for all tests to complete. It is categorised as a Execute tool in the Now Sdk Ext MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Now Sdk Ext MCP server in PolicyLayer and add a rule for run_atf_test_suite: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Now Sdk Ext. Nothing to install.
run_atf_test_suite is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the run_atf_test_suite rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for run_atf_test_suite. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
run_atf_test_suite is provided by the Now Sdk Ext MCP server (sonisoft-cnanda/now-sdk-ext-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Now Sdk Ext, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
