Domain Search King

Free hosted MCP server that suggests domain names and checks them against the registry (RDAP) before returning them, so an AI assistant only hands back names that were unregistered at check time. Three tools: find_available_domains (brandable .com names for a business idea), find_available_domains_by_pattern (names that start with, end with or contain a keyword, .com and .net by default) and check_domain (one domain's registration, backlinks, Wayback history and trademark links).
