# domains.lookup

Look up a domain and return normalized registration details. Combines registry and registrar RDAP and WHOIS sources to return the most accurate normalized fields across TLDs: availability, domain status, created/updated/expiry dates, registrar data, contact records, and nameservers. Use this when you need registrant-oriented summary data rather than raw WHOIS or RDAP payloads. Cost = 5 tokens.

  "id": 1,
  "method": "tools/call",

## Why domains.lookup is rated Low

This tool retrieves and queries domain registration information without creating, modifying, deleting, or executing actions. It is fundamentally a Read operation. Severity is medium rather than low because WHOIS/RDAP data can include sensitive registrant contact information (names, addresses, emails, phone numbers), which could enable privacy violations, phishing, or social engineering if misused by an agent to…

From the tool's own definition: "Tool description states it 'Look[s] up a domain and return[s] normalized registration details' from 'registry and registrar RDAP and WHOIS sources.' The verb is 'return,' indicating data retrieval with no modification."

## Use case

AI agents call domains.lookup to retrieve information from Vee3 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 Vee3:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "domains.lookup": {}
  }
}
```
