WHAT IT DOES

What kube_hunter_scan does on Pengstrike

AI agents invoke kube_hunter_scan to trigger actions in Pengstrike. 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 kube_hunter_scan is rated High

Kube-hunter is a well-known Kubernetes penetration testing/vulnerability hunting tool that actively probes cluster infrastructure. Running such a scan constitutes executing an external security operation with potentially significant blast radius — it could trigger alerts, expose cluster weaknesses, or be used in an attack chain.

From the tool's definition Tool name 'kube_hunter_scan' suggests execution of the kube-hunter security scanning tool against Kubernetes clusters; description is empty and uninformative, lowering confidence

RECOMMENDED RULE

The rule that runs kube_hunter_scan safely

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

kube_hunter_scan Rate-limited

kube_hunter_scan 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.
