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

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

## Why vpn_status is rated Low

The tool name 'vpn_status' strongly suggests a read-only query operation to check VPN connectivity or configuration state. This aligns with the 'Read' category (retrieves or queries data with no side effects). The empty description reduces confidence slightly, but the naming convention is clear. Status checks are non-destructive, non-modifying operations.

From the tool's own definition: "Tool name 'vpn_status' implies querying VPN connection state or configuration. The description is empty, limiting certainty."

## Use case

AI agents call vpn_status to retrieve information from Zebbern Kali MCP 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 Zebbern Kali MCP:

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