### Description (declared)

# domain-rdap-mcp

**Real, live domain registration lookups -- is it registered, when does it expire, who's the registrar -- free, in one command.**

```bash
pip install domain-rdap-mcp   # or: uvx domain-rdap-mcp
```

Then ask your agent: *"is example.com available?"* or *"when does getlulu.dev expire?"*

No API key. No signup. Free.

## Tools

| Tool | What the model sees it for |
|---|---|
| `check_domain(domain)` | Check whether a domain is registered, and if so its status, registration date, expiration date, and registrar. "Is domain-x.com available?", "when does domain-x.com expire?", "who registered domain-x.com?" |

Data comes from [RDAP](https://rdap.org) (Registration Data Access Protocol), the IETF-standardized, ICANN-mandated successor to WHOIS -- structured JSON instead of free-text, and it auto-routes to whichever registry actually holds the record.

## Examples

Registered domain:

```
> check_domain("getlulu.dev")
{
  "domain": "getlulu.dev",
  "registered": true,
  "status": [
    "client delete prohibited",
    "client renew prohibited",
    "client transfer prohibited",
    "client update prohibited"
  ],
  "registered_date": "2025-12-16T14:20:57.819Z",
  "expiration_date": "2027-12-16T14:20:57.819Z",
  "last_changed_date": "2025-12-21T14:20:57.819Z",
  "registrar": "GoDaddy.com, LLC",
  "attribution": "Domain registration data via RDAP (rdap.org), the IETF-standardized successor to WHOIS"
}
```

Unregistered (available) domain:

```
> check_domain("zzqx9v7k2m4p8qw-nosuchdomain-xk92.com")
{
  "domain": "zzqx9v7k2m4p8qw-nosuchdomain-xk92.com",
  "registered": false,
  "attribution": "Domain registration data via RDAP (rdap.org), the IETF-standardized successor to WHOIS"
}
```

A 404 from RDAP means the domain isn't registered -- that's a normal, meaningful "available" answer, not an error.

Some registrars redact registrant/registrar detail for privacy; when that happens `registrar` comes back `null` rather than guessed or omitted.
