概覽

AI 產生的概覽

已棄用的 Google UCP 代理式電商 MCP 伺服器，提供商品、購物車、結帳、訂單與配送工具，但不連接任何線上服務。

可以做什麼
  • 搜尋商家商品目錄，讀取商品詳情、價格、規格與庫存
  • 列出商家，並依地點查詢庫存與配送可用性
  • 建立、加入、檢視、清空購物車，取得配送選項
  • 發起結帳、套用付款方式並確認下單
  • 檢視、列出、取消訂單，申請退貨並追蹤物流
  • 連結買家身分，讀取買家資料與偏好
適用情境
僅適合參考或測試 UCP 工具介面，或你已有可用的 UCP 相容端點可指向。README 說明此套件已棄用且沒有任何工具會存取服務，因此目前無法用於實際購物。
執行需求
透過 npx 從 npm 套件 @codespar/mcp-ucp 在本機執行（需要 Node.js）。必須提供環境變數 UCP_API_KEY，以 Bearer 權杖送出；可選 UCP_MERCHANT_ID 與 UCP_SANDBOX。還需以 UCP_BASE_URL 指定可用位址，因為預設的 Google 端點會回傳 404 或 TLS 握手失敗。
安裝前請注意
此套件在 npm 上已棄用，且沒有工具會存取真實服務。UCP_API_KEY 會作為 Bearer 憑證隨每次請求送出，README 稱沒有入口網站核發這類憑證。工具包含結帳、付款、確認下單、取消與退貨，若設定真實端點將產生消費或變更訂單資料。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Mcp Ucp，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Desktop only，透過 STDIO。 STDIO 服務會啟動本機處理程序，因此需要 SourceWeft 桌面主機。

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.
