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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "lookup_mxrecords",
    "arguments": {
      "domain": "<domain>"
    }
  }
}
```

## Why lookup_mxrecords is rated Low

MX record lookups are read-only DNS queries that retrieve publicly available mail server configuration data. No side effects, no data modification, no code execution, and no financial transactions occur. The tool is designed for informational enrichment (B2B enrichment and email-deliverability checks).

From the tool's own definition: "Tool description states 'Get MX records and detect email provider' - a pure query operation with no modification, deletion, or execution capabilities. The example call shows a passive lookup: {'domain': 'openai.com'}."

## Use case

AI agents call lookup_mxrecords to retrieve information from GoCreative Agent API 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 GoCreative Agent API:

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