## Why get_cx_arp_table is rated Low

This tool retrieves network state information (ARP table entries) from a switch without creating, modifying, deleting, or executing any operations. ARP table queries are informational and pose minimal risk even if misused by an agent, as they cannot alter network configuration or state.

From the tool's own definition: "Tool name 'get_cx_arp_table' and description 'Get the ARP table from a CX switch' indicate data retrieval with no modification or side effects. The verb 'get' and the read-only nature of querying ARP tables confirm this is a retrieval operation."

## Use case

AI agents call get_cx_arp_table to retrieve information from API-Central 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 API-Central:

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