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

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

## Why cable_test is rated High

This tool actively triggers a hardware diagnostic test (TDR/cable test) on physical switch ports. It executes an operation on network infrastructure that sends electrical signals through cables, which could briefly disrupt port operation.

From the tool's own definition: "'Run a cable/TDR test on CX or AOS-S switch ports (async, polls ~60s)'"

## Use case

AI agents invoke cable_test to trigger actions in Hpe Networking. 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 Hpe Networking:

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