AI agents call list_tests to retrieve information from Mk Qa Master without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves metadata about available tests in a project. It performs discovery only—enumerating test files or test cases without executing, modifying, or deleting anything. This is purely informational and carries minimal risk even if misused by an AI agent, as it only reads test metadata.
From the tool's definition Tool is named 'list_tests' and described as using the runner's native collection mechanism to 'list out all executable tests' in the target project. This is a retrieval/query operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_tests gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mk Qa Master, and nothing reaches the server without passing your rules. This is the rule we recommend for list_tests:
{
"version": "1",
"default": "deny",
"tools": {
"list_tests": {}
}
}list_tests is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Mk Qa Master MCP server in PolicyLayer and add a rule for list_tests: 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 Mk Qa Master. Nothing to install.
list_tests 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 list_tests 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 list_tests. 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.
list_tests is provided by the Mk Qa Master MCP server (kao273183/mk-qa-master). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mk Qa Master, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
