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

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

## Why list_subdomains is rated Low

This tool retrieves subdomain information from a cPanel account without creating, modifying, or deleting any resources. It is a straightforward data retrieval function with no side effects. The severity is low because while subdomain enumeration could inform reconnaissance, unauthorized access to the MCP server itself is the primary control, and this tool simply returns existing configuration data.

From the tool's own definition: "Tool name 'list_subdomains' and description 'List all subdomains' indicate a query operation that retrieves data without modification. The verb 'list' is a classic read-only operation."

## Use case

AI agents call list_subdomains to retrieve information from cPanel MCP Server 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 cPanel MCP Server:

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