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

## Why nuclei_scan is rated High

Nuclei is a widely recognized open-source vulnerability scanner that executes active probes against target systems to detect vulnerabilities. Even with an empty description, the tool name combined with the offensive security context of this server (penetration testing platform with sibling tools for payload generation, attack suites, and wireless cracking) strongly implies it runs active network scans against…

From the tool's own definition: "Tool name 'nuclei_scan' on a penetration testing platform alongside tools like 'advanced_payload_generation', 'ai_generate_attack_suite', and 'aircrack_ng'. Nuclei is a well-known vulnerability scanning tool that actively probes targets."

## Use case

AI agents invoke nuclei_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": {
    "nuclei_scan": {
      "limits": [
        {

          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
