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

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

## Why run_nbtscan is rated High

NBTScan executes network reconnaissance actions against target systems to enumerate NetBIOS names and information. While classified as reconnaissance rather than destructive, it triggers external network operations whose effects depend on the target arguments provided. The tool enables autonomous execution of a security scanning tool, making it Execute-category.

From the tool's own definition: "Tool named 'run_nbtscan' is part of a penetration testing MCP server designed to 'autonomously execute over 200 open-source penetration testing tools' with 'reconnaissance, web exploitation, and brute-forcing' capabilities."

## Use case

AI agents invoke run_nbtscan to trigger actions in Pentester-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 Pentester-MCP:

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