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

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

## Why monitor_network_arp_list is rated Low

This tool retrieves network ARP table information (IP-to-MAC address mappings) without any capability to modify, delete, or execute operations. It is a read-only query of existing network state data. The blast radius of misuse is minimal—an attacker could gain visibility into network topology but cannot alter configurations, execute commands, or cause damage.

From the tool's own definition: "Tool name contains 'monitor' and 'list', and description states 'Get the ARP table'. The word 'Get' and 'list' indicate data retrieval with no modification capability."

## Use case

AI agents call monitor_network_arp_list to retrieve information from FortiOS 7 6 X MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches FortiOS 7 6 X MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "monitor_network_arp_list": {}
  }
}
```
