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

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

## Why nuclei_web_scan is rated High

This tool runs the Nuclei security scanner against web applications, which actively probes targets with exploit templates and vulnerability checks. It executes external operations against potentially live systems, making it Execute category. The blast radius is high because it can trigger intrusive security tests against targets, potentially causing disruption or being used offensively against unauthorized systems.

From the tool's own definition: "Execute Nuclei web application security scan"

## Use case

AI agents invoke nuclei_web_scan to trigger actions in Kali Security MCP. 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 Security MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "nuclei_web_scan": {
      "limits": [
        {

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