ZonRival gives Amazon sellers a full competitor teardown in about 30 seconds. Paste any product and get: what its buyers complain about, from Amazon's summary of all reviews (mention counts, % negative, quotes) 90 days of best-seller rank, price and review history (Keepa data) a 0-100 listing audit with specific fixes who ranks organically and who's advertising on its main keyword plain-English takeaways and a shareable public report link Sellers can then watch any competitor (Amazon products or Shopify stores) and get an email when its price, stock, rank or complaints change. Two ways to use it, one account and credit balance: Web app at zonrival.com/app, with a free no-sign-up preview and one-click Google sign-in. MCP connector for Claude, ChatGPT, Cursor and Claude Code (10 tools). Approved and published in Claude's official connector directory, and listed in the official MCP Registry, Glama (quality A) and Smithery.
