|Overview
The @lulzasaur9192/mcp-domain-info MCP server enables programmatic access to domain intelligence data. It supplies tools for retrieving WHOIS information, checking availability, and analyzing domain metadata directly in LLM workflows or applications.
Key Capabilities
- domain_info: Returns WHOIS details like registrant name, organization, registration and expiration dates, nameservers, and status flags.
- domain_availability: Queries if a domain is registered or available for purchase.
- domain_metadata: Fetches additional records such as IP addresses, DNS records, and historical changes.
Use Cases
- Security Reconnaissance: Use domain_info to investigate phishing domains by pulling registrant data and nameservers for attribution.
- App Domain Validation: Integrate domain_availability in registration forms to check if user-suggested domains are free.
- OSINT Workflows: Chain domain_metadata with other tools to map attack infrastructure via DNS and WHOIS correlations.
- Domain Portfolio Management: Query multiple domains with domain_info to track expirations and renewals.
Who This Is For
Web developers building domain management apps, cybersecurity analysts conducting threat hunting, OSINT researchers, and DevOps teams automating infrastructure audits.
