概覽

AI 產生的概覽

遠端 MCP 伺服器,提供免費且結果確定的商務與資料工具:毛利、定價、商品目錄稽核、文字/JSON/CSV/HTML 處理,以及 x402 付費路由探索。

可以做什麼
  • 計算單位毛利、加成率、損益兩平銷量、目標價格、清潔服務報價、電商淨貢獻、獲客成本與訂閱 LTV
  • 批次稽核電商商品目錄:重複 SKU、缺少屬性、錯誤連結,並比對匯入批次的價格、幣別與庫存異常
  • 清除連結中的追蹤參數、產生 URL slug、解析並檢視 JSON、把 CSV 轉成 JSON、從提供的 HTML 擷取標題、meta、標題層級與 JSON-LD
  • 讀取美國 Google Trends 近期上升搜尋詞並給出啟發式購買意圖分類
  • 把代理任務路由到支援的 Penny Engine 能力,並提供付費路由報價與結帳說明
  • 從支援的 Allbirds 與 tentree 商品連結取得公開中繼資料與變體資訊,附雜湊與變更比對
適用情境
適合需要快速、可重複的商務計算、商品目錄或抓取資料品檢,以及小型文字與資料轉換而不必寫程式的場合。也適合想先探索並預檢 x402 付費路由、再決定是否購買的代理。
執行需求
遠端 streamable HTTP 端點;未宣告任何套件、環境變數或請求標頭。免費工具不需註冊或 API 金鑰。需要能連線該託管端點的網路;趨勢工具依賴公開 RSS,商品證據工具依賴支援的零售商連結。
安裝前請注意
部分工具說明了 0.001 USDC 的結帳路由;預檢與選擇工具聲明不會扣款、簽章或執行付費呼叫,但實際付款需買方授權並涉及加密貨幣。目錄與匯入工具會接收商品資料,商品證據工具會抓取公開零售頁面。報價與啟發式分類應視為估算。
