Onymu
Server Details
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.

Scored across 12 tools
Each tool targets a distinct resource and action: domain search, generation, appraisal, username checking, favorites management, saved domains, and history reads. The two history tools (get_recent_generations vs get_recent_searches) are clearly separated by their context, and all CRUD pairs are unambiguous.
All tool names follow a consistent verb_noun pattern in snake_case (add_, appraise_, check_, generate_, get_, list_, remove_, save_, search_). The verbs accurately describe the action and nouns identify the entity, making the API predictable.
12 tools is well-scoped for a domain/name management server. Each tool serves a clear purpose: search, generate, appraise, check usernames, manage favorites, manage saved domains, and retrieve history. There is no bloat or trivial tools.
The surface covers the full lifecycle: discovery (search, generate), evaluation (appraise, check_usernames), persistence (save/remove saved_domains, add/remove favorite_tlds), and retrieval (list_saved_domains, list_favorite_tlds, get_recent_*). The tools are designed to complement each other (e.g., appraise_domain explicitly directs to search_domains for availability). No obvious dead ends or missing operations.
