概覽

AI 產生的概覽

針對 Nuvem Fiscal 的本機 MCP 伺服器，讓助理開立、查詢與取消巴西電子稅務單據，並查詢 CNPJ 與 CEP 資料。

可以做什麼
建立、查詢與取消 NF-e、NFS-e、NFC-e、CT-e 與 MDF-e 稅務單據，包括關閉 MDF-e、查詢 NF-e 批次狀態與事件。為 NF-e 與 CT-e 送出更正函（CCe）。依 CNPJ 查詢公司資料，依 CEP 查詢地址。註冊公司並為其上传 A1 數位憑證。列出帳戶中已註冊的公司。
適用情境
適合需要助理透過 Nuvem Fiscal 處理巴西稅務與開立發票流程的情境：開立或取消稅務單據、送出更正函，或查詢 CNPJ 與 CEP 資料。在接觸真實稅務系統前，先在 homologation 環境或示範模式測試。
執行需求
透過 npx 在本機執行（需要 Node.js）。需要 Nuvem Fiscal 帳戶與 OAuth2 用戶端憑證，透過環境變數 NUVEM_FISCAL_CLIENT_ID 與 NUVEM_FISCAL_CLIENT_SECRET 提供；需要連線至 Nuvem Fiscal API 的網路。設定 MCP_DEMO=true 或 --demo 可離線執行示範模式。
安裝前請注意
此伺服器可建立、取消與更正真實稅務單據並註冊公司，操作失誤會影響實際稅務紀錄，建議先在 homologation 環境或示範模式試用。它涉及 OAuth2 用戶端憑證與 A1 數位憑證（.pfx）等敏感機密。單據資料會傳送至 Nuvem Fiscal API。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Mcp Nuvem Fiscal，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。

Authentication

Nuvem Fiscal uses OAuth2 client credentials. The server automatically manages token refresh.

Sandbox / Testing

Nuvem Fiscal supports a homologation environment (ambiente=2) for testing fiscal document emission without affecting real tax systems.

Demo Mode

Set MCP_DEMO=true (or pass --demo) to run the server without contacting the Nuvem Fiscal API. In MCP_DEMO=true mode, create_nfse issues distinct fixture IDs per call within one process and echoes input servico.codigo, valor, and servico.descricao into the response. pdf_url is templated from the fixture id. Other demo tools return static fixtures and are useful for offline walkthroughs and integration smoke tests.

Get your credentials

  1. Go to Nuvem Fiscal Developer Portal
  2. Create an account
  3. Register an application to get OAuth2 credentials
  4. Set the environment variables

Environment Variables
