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

```json
{
  "jsonrpc": "2.0",

## Why rustscan_fast_scan is rated High

RustScan is a port scanner that actively probes remote hosts, constituting execution of network reconnaissance operations against external systems. The empty description lowers confidence slightly, but the tool name and server context strongly imply active scanning execution.

From the tool's own definition: "Tool name 'rustscan_fast_scan' on a penetration testing platform; RustScan is a well-known fast port scanner used in offensive security contexts."

## Use case

AI agents invoke rustscan_fast_scan 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.

## Recommended policy (PolicyLayer)

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

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