  • 4-endpoint Base RPC pool with automatic failover
  • Rate limiting (per-IP, 60/min search, 20/min purchase)
  • 200 concurrent users: 0% error, p95=1.09s
  • skills-lite.json: 4.5MB (down from 30MB skills.json)

  • GitHub issue opened on modelcontextprotocol/servers
  • Smithery listing (84/100 quality score)
  • Glama.ai indexed
  • mcp.so listing (stale — needs manual update)

What's next

  1. Reddit + Hacker News — posts ready, need to publish
  2. Google indexing — SEO content restored, requesting recrawl
  3. Seller onboarding — make it easy for developers to publish skills
  4. More AI crawlers — ChatGPT and Claude should be able to find and recommend MarketNow
  5. Chinese platforms — Gitee, CSDN, Zhihu (need Chinese phone for Baidu verification)
