Onymu is an MCP server for domain name search, domain availability checking, and social media username lookup. Check a domain name against hundreds of TLDs in one call, including .com, .io, .ai, .co, and country-code extensions. Generate brandable startup names, business names, and product names from a keyword, and instantly see which ones are still available to register. Check username availability across major social networks so a brand name comes with matching handles. Save domains, set favorite TLDs, and recall recent searches to keep name research organized across sessions.
Twitter/X, YouTube, Reddit, Google and more - 100+ endpoints in total. No account, no OAuth, no subscription. Pay per call in USDC, or top up once and spend one balance across all of them.
