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

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

## Why raw_tcp_exchange is rated High

The name implies establishing raw TCP connections and exchanging data with external endpoints, which constitutes executing external network operations. This could be used to communicate with arbitrary hosts, exfiltrate data, or interact with network services. Severity is high due to potential for network-based attacks or data exfiltration, but confidence is reduced because the description is empty.

From the tool's own definition: "Tool name 'raw_tcp_exchange' suggests sending/receiving raw TCP data to arbitrary hosts; description is empty and uninformative."

## Use case

AI agents invoke raw_tcp_exchange to trigger actions in Allcanuse. 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 Allcanuse:

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