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.
The PostNitro MCP server lets AI assistants and agents — Claude (Desktop, Code, and Cowork), Cursor, ChatGPT, and any other Model Context Protocol client — create carousels, image posts, and videos, manage brand kits, audio tracks, and connected social accounts, and schedule posts directly. Instead of writing REST API calls, you connect the server once and your AI assistant gets ready-made tools covering carousel, image, and video generation, brands, audio, social accounts, and scheduling.

Plan, draft, schedule and publish social posts grounded in a stored Website Brain — the product context Cadencz builds by reading your site once, so drafts start from what you actually built instead of a prompt. 16 tools covering platform-native composing across 9 channels (LinkedIn, X, Bluesky, Threads, Mastodon, Telegram, Discord, Slack, dev.to), weekly planning, scheduling and analytics. Nothing publishes without human approval.
Crevio's MCP server lets an agent run a real online business, not just read from one. It exposes a delegation surface (ask_crevio, start_task, wait_for_run, send_message, resolve_approvals) plus code_search and code_execute for calling the full Crevio REST API - products, customers, orders, email, socials, and sites.
