概覽

AI 產生的概覽

已棄用的 Nubank 銀行 MCP 伺服器（採用 Open Finance Brasil）；其 API 主機已無法解析，沒有任何工具能連上線上服務。

可以做什麼
  • 讀取帳戶、餘額、對帳單、交易與個人資料
  • 讀取信用卡帳單、卡片交易與卡片詳情
  • 讀取投資與收益，以及已登記的 PIX 金鑰
  • 發起、預約與取消 PIX 轉帳，建立或刪除 PIX 金鑰
  • 凍結或解凍卡片，繳付信用卡帳單與 boleto
  • 注意：README 指出此伺服器中沒有任何工具能連上服務，因為 API 主機無法透過 DNS 解析。
適用情境
僅適合當作參考，了解 Nubank Open Finance MCP 伺服器過去如何建置。它已棄用，無法用於實際銀行業務；若需要 NuPay for Business，README 指向另一個套件。
執行需求
透過 npx 在本機執行的 Node.js 程序。README 將 NUBANK_CLIENT_ID、NUBANK_CLIENT_SECRET 與 NUBANK_CERT_PATH（mTLS 憑證路徑）列為必要，另有選用的 MCP_HTTP 與 MCP_PORT。憑證需向 Nubank 的 Open Finance 入口取得。清單中只宣告了 NUBANK_CLIENT_ID。
安裝前請注意
已棄用且無法使用：API 主機無法解析，套件在 npm 上已棄用。所列工具會轉移資金並改變帳戶狀態（PIX 轉帳、信用卡與 boleto 繳款、凍結卡片、建立與刪除 PIX 金鑰）。它要求 OAuth2 用戶端密鑰與 mTLS 憑證路徑。README 另提到商業化的企業版服務。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Mcp Nubank，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。

@codespar/mcp-nubank

Deprecated: no live endpoint. Measured on 2026-09-27 against two public DNS resolvers (8.8.8.8 and 1.1.1.1): api.nubank.com.br, the host this server calls, does not resolve in DNS. Nubank's only public API we found is NuPay for Business (api.spinpay.com.br), which @codespar/mcp-nupay already covers. 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 NUBANK_BASE_URL. To bring the package back, open an issue in mcp-dev-latam with the provider's documented base URL.
