AI agents call snow_get_atf_results to retrieve information from Serac without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns test execution data (pass/fail status, error details, execution time) without modifying any state. It has no side effects on the ServiceNow instance. The blast radius of misuse is minimal—an agent could access test result information but cannot alter tests, delete results, or trigger external actions. This is a straightforward data retrieval operation.
From the tool's definition Tool description states it "Retrieves ATF test execution results" from the sys_atf_test_result table. The verb 'retrieves' and absence of any mutation language (create, update, delete, modify) indicate a read-only query operation.
Attacks that exploit this kind of access
Retrieves ATF test execution results including pass/fail status, error details, and execution time from sys_atf_test_result table. It is categorised as a Read tool in the Serac MCP Server, which means it retrieves data without modifying state.
Register the Serac MCP server in PolicyLayer and add a rule for snow_get_atf_results: 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.
snow_get_atf_results is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the snow_get_atf_results 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 snow_get_atf_results. 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.
snow_get_atf_results is provided by the Serac MCP server (serac-labs/serac). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
