概览

AI 生成的概览

已弃用的 Nubank 银行 MCP 服务器（基于 Open Finance Brasil）；其 API 主机已无法解析，没有任何工具能连到在线服务。

可以做什么
  • 读取账户、余额、对账单、交易与个人资料
  • 读取信用卡账单、卡交易与卡片详情
  • 读取投资与收益，以及已登记的 PIX 密钥
  • 发起、预约与取消 PIX 转账，创建或删除 PIX 密钥
  • 冻结或解冻卡片，支付信用卡账单与 boleto
  • 注意：README 说明该服务器中没有任何工具能连到服务，因为 API 主机无法通过 DNS 解析。
适用场景
仅适合作为参考，了解 Nubank Open Finance MCP 服务器曾如何搭建。它已弃用，无法用于真实银行业务；如需 NuPay for Business，README 指向另一个软件包。
运行要求
通过 npx 在本地运行的 Node.js 进程。README 将 NUBANK_CLIENT_ID、NUBANK_CLIENT_SECRET 与 NUBANK_CERT_PATH（mTLS 证书路径）列为必需，另有可选的 MCP_HTTP 与 MCP_PORT。凭据需从 Nubank 的 Open Finance 门户获取。清单中只声明了 NUBANK_CLIENT_ID。
安装前请注意
已弃用且不可用：API 主机无法解析，软件包在 npm 上已弃用。所列工具会转移资金并改变账户状态（PIX 转账、信用卡与 boleto 付款、冻结卡片、创建与删除 PIX 密钥）。它要求 OAuth2 客户端密钥与 mTLS 证书路径。README 还提到商业化的企业版服务。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Mcp Nubank，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。

@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.
