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

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

## Why kali_network_nmap_discover is rated High

This tool actively executes Nmap network discovery scans against target hosts/networks, sending packets (ARP, ICMP, TCP, UDP) to enumerate live systems. It is an active external operation whose effects depend on arguments (target network range, discovery method).

From the tool's own definition: "Discover live hosts on a network using Nmap. Supports ping, ARP, TCP, UDP, and ICMP discovery methods."

## Use case

AI agents invoke kali_network_nmap_discover 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
