Check Domain Availability

The `check_domain_availability` tool instantly tells you if a name is free for registration. Cascade figures out if your project needs a domain and runs this check automatically, so you don't have to prompt it step by step. It handles the initial market validation phase of any build. Just tell Windsurf your goal—like 'find us a new brand name’—and it checks availability across multiple domains for you.

WHOIS and IP Geolocation Data

You can run `get_whois_record` to pull the full, raw WHOIS data for any domain. This gives deep insight into who owns a site and when it was registered. It's essential background work before you start writing code. If the record is vague, Cascade pivots. You can then use `get_ip_geolocation` on associated IP addresses to pinpoint where that owner or server is actually located.

Email and Domain Validation

The `verify_email` tool checks if an email address is legitimate and active. It stops you from deploying code using fake contact info. You can combine this with the `check_domain_availability` tool to validate a whole corporate setup. Windsurf automatically confirms both the domain exists and that key contact emails are actually deliverable.

Common questions about WhoisXML MCP in Windsurf

You set a goal, and Cascade handles the rest. For example, you can ask it to validate a potential client's setup. It will run `check_domain_availability` first, then check the associated emails using `verify_email`, all without you needing to prompt each step.

This MCP Server provides domain intelligence, IP geolocation coordinates, full WHOIS records, and email validation status. It's a mix of public registration data and network location information.

Yes. Because the server is designed for multi-step execution, you can chain `check_domain_availability` across a list of names. Cascade runs these checks sequentially until it hits an available domain.

The server touches public registration data, IP addresses, and email formats. While the raw WHOIS records contain sensitive ownership details, your AI client only processes this data to confirm status or location for your use.

Its core job is giving you deep intelligence on digital assets. It lets you check domain availability, verify emails, and map out the ownership and location details tied to a website's IP.
