## Description

SSL certificate monitoring and domain registration information MCP server that provides real-time SSL certificate validation and WHOIS domain lookup capabilities. Built by firesh, the implementation uses both modern RDAP protocol and traditional WHOIS queries as fallback to retrieve comprehensive domain registration data including expiration dates, registrar information, and registrant details, while SSL certificate checking leverages Node.js TLS connections to validate certificate chains and calculate expiration timelines. Designed for system administrators, security teams, and developers who need automated monitoring of domain and certificate lifecycles without manual certificate inspection or complex WHOIS parsing, making it valuable for compliance tracking, security auditing, and proactive renewal management workflows.
