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

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

## Why discover_network is rated High

This tool performs active network discovery scanning, which constitutes an external operation that probes network devices and medical systems. In a hospital context, unauthorized or misconfigured network scanning can disrupt critical medical devices (e.g., infusion pumps, imaging systems), making misuse potentially dangerous.

From the tool's own definition: "'扫描本地网络设备和医疗系统' (scan local network devices and medical systems) — actively probes and scans network infrastructure"

## Use case

AI agents invoke discover_network to trigger actions in Hospital Vuln Scanner. 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 Hospital Vuln Scanner:

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