What kube_bench_cis does on Nyxstrike
AI agents invoke kube_bench_cis to trigger actions in Nyxstrike. 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.
Why kube_bench_cis is rated High
kube-bench is a well-known tool that checks Kubernetes clusters against CIS benchmarks, implying it executes scans against live infrastructure. On an offensive security platform alongside tools like aircrack_ng and payload generators, this likely executes active security assessments. Empty description lowers confidence, but the tool name and server context strongly suggest active execution against systems.
From the tool's definition Tool name 'kube_bench_cis' on an offensive security/penetration testing platform; description is empty and uninformative.
Attacks that exploit this kind of access
The rule that runs kube_bench_cis safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Nyxstrike, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For kube_bench_cis, this is the rule to start with:
kube_bench_cis 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Nyxstrike, apply this rule, and every kube_bench_cis call is checked against it from then on.
Questions about kube_bench_cis
kube_bench_cis is a execute tool on the Nyxstrike MCP server. It is categorised as a Execute tool in the Nyxstrike MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Nyxstrike MCP server in PolicyLayer and add a rule for kube_bench_cis: 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 Nyxstrike. Nothing to install.
kube_bench_cis 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 kube_bench_cis 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 kube_bench_cis. 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.
kube_bench_cis is provided by the Nyxstrike MCP server (CommonHuman-Lab/nyxstrike). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
