概覽

AI 產生的概覽

遠端 MCP 伺服器,讓助理估算物品價值、比較全新、二手與轉售價格,並找出購買或出售的管道。

可以做什麼
  • 依名稱或照片估算單件物品價值,提供全新與二手價格區間及信心分數
  • 並排比較全新、二手與轉售價格,判斷能省多少或能賺多少
  • 提供購買全新、購買二手或出售的商店與交易平台連結
  • 在支援的用戶端中以可互動的價格卡片呈現結果
適用情境
適合二手挖寶、轉賣、為庭院拍賣或收藏品定價,或判斷買二手是否比買全新划算。想快速判斷某個開價是否合理時也很有用。
執行需求
需要遠端 Streamable HTTP 端點;不需帳號、登入、API 金鑰或環境變數。適用於支援遠端 MCP 伺服器的用戶端,例如 Claude、Cursor、ChatGPT 開發人員模式、VS Code 或其他 MCP 用戶端。
安裝前請注意
價格來自即時商品刊登,僅為估算而非報價,應作為參考而非正式鑑價。服務免費但有每日查詢次數限制。提交的照片或物品名稱會傳送給第三方服務,分享私人物品圖片前請先查看其隱私條款。

README

[Worth]

Worth

Never overpay, never undersell.
Ask your AI "what's it worth?" about anything (thrift finds, collectibles, electronics, vintage) and get its resale value, used price and new price, plus links to the best place to buy or sell.

[Add to Cursor] [Install in VS Code]

[Worth price card in Claude]

What you get

  • A fair price in seconds. Name it or snap a photo; get an estimate with a confidence score.
  • Know if used is worth it. See new vs. used vs. resale side by side, and how much you save or can earn.
  • The best place to buy or sell. Direct links to stores and marketplaces, matched to what you want to do.

Great for thrift flipping, reselling for beginners, pricing yard sale items, or deciding whether to buy used instead of new. No account, no sign-in. Prices come from live listings and are estimates, not offers.
