## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "kube_bench_cis",
    "arguments": {}
  }
}
```

## Why kube_bench_cis is rated High

kube-bench executes security compliance checks against a live Kubernetes cluster by querying cluster configuration and running diagnostic commands. This constitutes execution of external operations against infrastructure. Empty description lowers confidence, but the tool name strongly implies active scanning/execution against a Kubernetes environment.

From the tool's own definition: "Tool name 'kube_bench_cis' suggests running kube-bench, a tool that checks Kubernetes clusters against CIS benchmarks. The description is empty, so classification is based on name alone."

## Use case

AI agents invoke kube_bench_cis 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Pengstrike:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "kube_bench_cis": {
      "limits": [
        {
          "counter": "kube_bench_cis_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
