概览

AI 生成的概览

远程 MCP 服务器,提供免费的确定性商务与数据工具:毛利、定价、商品目录审计、文本/JSON/CSV/HTML 处理,以及 x402 付费路由发现。

可以做什么
  • 计算单位毛利、加价率、盈亏平衡销量、目标价格、清洁服务报价、电商净贡献、获客成本与订阅 LTV
  • 批量审计电商商品目录:重复 SKU、缺失属性、错误链接,并对比导入批次的价格、币种与库存异常
  • 清理链接中的跟踪参数、生成 URL slug、解析并检查 JSON、把 CSV 转为 JSON、从提供的 HTML 中提取标题、meta、标题层级与 JSON-LD
  • 读取美国 Google Trends 近期上升搜索词并给出启发式购买意图分类
  • 把代理任务路由到受支持的 Penny Engine 能力,并给出付费路由报价与结账说明
  • 从受支持的 Allbirds 与 tentree 商品链接获取公开元数据与变体信息,附哈希与变更对比
适用场景
适合需要快速、可重复的商务计算、商品目录或抓取数据质检,以及小型文本与数据转换而无需写代码的场景。也适合想先发现并预检 x402 付费路由、再决定是否购买的代理。
运行要求
远程 streamable HTTP 端点;未声明任何软件包、环境变量或请求头。免费工具无需注册或 API 密钥。需要能访问该托管端点的网络;趋势工具依赖公开 RSS,商品证据工具依赖受支持的零售商链接。
安装前请注意
部分工具描述了 0.001 USDC 的结账路由;预检与选择工具声明不会扣款、签名或执行付费调用,但实际支付需买家授权并涉及加密货币。目录与导入工具会接收商品数据,商品证据工具会抓取公开零售页面。报价与启发式分类应视为估算。
