Google UCP — agentic shopping, cart, checkout, orders, delivery

已验证STDIO仅桌面金融商业与电商

概览

AI 生成的概览

已弃用的 Google UCP 智能体电商 MCP 服务器，提供商品、购物车、结账、订单与配送工具，但不连接任何在线服务。

可以做什么
  • 搜索商家商品目录，读取商品详情、价格、规格与库存
  • 列出商家，并按地点查询库存与配送可用性
  • 创建、添加、查看、清空购物车，获取配送选项
  • 发起结账、应用支付方式并确认下单
  • 查看、列出、取消订单，申请退货并追踪物流
  • 关联买家身份，读取买家资料与偏好
适用场景
仅适合参考或试验 UCP 工具接口，或你已有可用的 UCP 兼容端点可供指向。README 说明该包已弃用且没有任何工具会访问服务，因此目前无法用于真实购物。
运行要求
通过 npx 从 npm 包 @codespar/mcp-ucp 本地运行（需要 Node.js）。必须提供环境变量 UCP_API_KEY，以 Bearer 令牌发送；可选 UCP_MERCHANT_ID 与 UCP_SANDBOX。还需通过 UCP_BASE_URL 指定可用地址，因为默认的 Google 端点返回 404 或 TLS 握手失败。
安装前请注意
该包在 npm 上已弃用，且没有工具会访问真实服务。UCP_API_KEY 会作为 Bearer 凭据随每次请求发送，README 称没有门户签发此类凭据。工具包含结账、支付、确认下单、取消与退货，若配置了真实端点将产生消费或改动订单数据。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Mcp Ucp，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

README

@codespar/mcp-ucp

Deprecated: no live endpoint. Measured on 2026-09-27: commerce.googleapis.com answers every path with Google's generic Error 404 (Not Found) page, and sandbox.commerce.googleapis.com (used with UCP_SANDBOX=true) fails the TLS handshake, because the certificate served there covers *.googleapis.com and not the extra label. UCP is an open specification, not an API Google hosts. No tool in this server reaches a service. The package is deprecated on npm and stays in this repository for reference only. If you have a working endpoint, point the server at it with UCP_BASE_URL. To bring the package back, open an issue in mcp-dev-latam with the provider's documented base URL.

MCP server for Google UCP — Universal Commerce Protocol for agentic shopping, cart, checkout, orders, and delivery

[npm] [License: MIT]

What is UCP?

Universal Commerce Protocol (UCP) is Google's open standard for agentic commerce. It enables AI agents to autonomously discover products, build carts, checkout, manage orders, and track deliveries — without screen-scraping or bespoke merchant integrations.

UCP works alongside AP2 (payment processing) and A2A (agent-to-agent interoperability), with MCP as the transport layer.

UCP_SANDBOXNotrue switches BASE_URL to https://sandbox.commerce.googleapis.com/ucp/v1, which fails TLS

Links

Enterprise

Need governance, budget limits, and audit trails for agent payments? CodeSpar Enterprise adds policy engine, payment routing, and compliance templates on top of these MCP servers.

Authentication

The server sends UCP_API_KEY as an Authorization: Bearer header and UCP_MERCHANT_ID as an X-Merchant-Id header on every request (src/index.ts:78-83).

There is no portal issuing those credentials. The developer portal this README used to link, developers.google.com/agents/commerce, answers HTTP 404.
