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

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

## Why list_established_connections is rated Low

This tool reads and reports existing network connection state without altering system configuration or data. No side effects or reversible modifications occur. Severity is medium rather than low because network connection information can reveal sensitive architecture and running services; however, it is read-only.

From the tool's own definition: "Tool name 'list_established_connections' indicates retrieval of network connection data with no modification capability. The 'list' verb and 'established_connections' noun are consistent with query/read operations."

## Use case

AI agents call list_established_connections to retrieve information from Allcanuse 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 Allcanuse:

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