WHOIS & Domain Lookup Service

Domain registration, WHOIS information, and domain availability checking

Get Started NowDocumentation

Overview

WHOIS & Domain Lookup Service gives AI agents access to domain registration data through a managed whois api — the authoritative record of who owns every domain on the internet and when registrations expire, delivering the full depth of a domain whois api without requiring developers to parse raw WHOIS responses from individual registries.

It acts as a standardized bridge between large language models and live domain registry data. Instead of relying on outdated domain information or building a custom whois lookup api integration that handles multiple registry formats, models can retrieve current registration details and check real-time availability through a controlled MCP interface.

By integrating WHOIS & Domain Lookup Service, developers enable AI agents to:

• Retrieve full registration details for any domain using lookup_domain — including creation date, expiry date, registrar name, nameservers, registrant organisation, and DNSSEC status • Determine whether a specific domain name is available to register with check_availability — functioning as a whois api free equivalent • Check multiple domains simultaneously using bulk_check_availability — invaluable for finding available brand name variations or monitoring target domain watchlists • Support cybersecurity investigations by identifying domain ownership, registration history, and nameserver configurations

This MCP is useful for domain research agents, brand protection monitoring, competitive intelligence tools, cybersecurity investigation pipelines, startup naming assistants, and domain investment research workflows that require reliable domain whois api data.
