WHAT IT DOES

What snow_execute_atf_test does on Serac

AI agents invoke snow_execute_atf_test to trigger actions in Serac. 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.

RISK

Why snow_execute_atf_test is rated High

This tool runs code (test suites) whose effects depend on what those tests do and the current state of the ServiceNow instance. While tests are typically read-only in intent, execution itself is a code-running operation that can have side effects depending on test design.

From the tool's definition Tool name contains 'execute' and description states 'Executes an ATF test or test suite and returns the results.' ATF (Automated Test Framework) execution triggers test operations with outcomes determined by test content and ServiceNow state.

RECOMMENDED RULE

The rule that runs snow_execute_atf_test safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Serac, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For snow_execute_atf_test, this is the rule to start with:

snow_execute_atf_test Rate-limited

snow_execute_atf_test 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.

Questions about snow_execute_atf_test

What does the snow_execute_atf_test tool do? +

Executes an ATF test or test suite and returns the results. Tests run asynchronously in ServiceNow using sys_atf_test_result table. It is categorised as a Execute tool in the Serac MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on snow_execute_atf_test? +

Register the Serac MCP server in PolicyLayer and add a rule for snow_execute_atf_test: 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 Serac. Nothing to install.

What risk level is snow_execute_atf_test? +

snow_execute_atf_test is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit snow_execute_atf_test? +

Yes. Add a rate_limit block to the snow_execute_atf_test 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.

How do I block snow_execute_atf_test completely? +

Set action: deny in the PolicyLayer policy for snow_execute_atf_test. 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.

What MCP server provides snow_execute_atf_test? +
