Frequently asked questions about the WhoisXML MCP Server

Can I check if a domain is available for registration?

Yes! Use the check_domain_availability tool. It provides a lightweight check to see if a specific domain name is currently available.

How do I find the physical location of an IP address?

Simply use the get_ip_geolocation tool with the target IP. The agent will return the country, city, latitude, longitude, and ISP information.

Can this tool detect disposable or fake email addresses?

Yes. The verify_email tool checks email syntax, MX records, and SMTP connections, and specifically flags disposable email providers.

We built the connector to WhoisXML. Now put your agents to work. Fully governed.

Vinkius is the AI Gateway with managed hosting. Stop building connectors. Every connection runs inside eight layers of security.

How it works

Infrastructure

Hosted, sandboxed, and live on AWS. You don't provision anything. You don't maintain anything. You connect.

Visibility

Every tool call, every token, every response. Logged and auditable. Data flows direct from WhoisXML to your agent. Nothing is stored on our side. Ever.

Control

Eight governance layers on every request. Sensitive data redacted before it reaches the model. Kill switch if anything goes sideways. Always on.
