## Why kali_web_nuclei_scan is rated High

Nuclei is an active vulnerability scanner that sends crafted HTTP/network probes to target systems to detect CVEs and misconfigurations. This constitutes executing external operations against targets, not merely reading data. Misuse could result in scanning unauthorized systems, triggering security alerts, or exploiting vulnerabilities during the scanning process.

From the tool's own definition: "'vulnerability scanner' using 'Template-based' execution against targets, with 'extensive CVE coverage and custom templates support' — actively probes external systems for vulnerabilities"

## Use case

AI agents invoke kali_web_nuclei_scan to trigger actions in Kali MCP Server. 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 Kali MCP Server:

```json
