概覽

AI 產生的概覽

將助理連接到 Facturalia 帳戶，用來建立發票與貸項通知單，並查詢發票是否已寄送與已付款。

可以做什麼
  • 依編號查詢單張發票的寄送與付款狀態
  • 依編號查詢單張貸項通知單的付款狀態
  • 依客戶與明細資料建立正式銷售發票
  • 依客戶與明細資料建立正式貸項通知單
  • 查看每月工具呼叫用量並管理訂閱方案
適用情境
適合在 Facturalia 中管理開票作業、希望助理在對話中草擬並開立發票或貸項通知單，或不必開啟 Facturalia 介面就能查詢某張發票是否已寄送、已付款的情境。
執行需求
透過 streamable HTTP 連線的遠端 MCP 端點，不需本機安裝。以 OAuth 登入，首次連線時需提供自己的 Facturalia 正式 API 金鑰（以 fac_live_ 開頭，位於 Facturalia 的 API 模組）。需要 Facturalia 帳戶；免費方案每月 50 次工具呼叫。
安裝前請注意
建立類工具會在正式 Facturalia 帳戶中產生真實單據並計入帳戶發票數量，不會自動以電子郵件寄送；應傳入 external_id 以免重試時重複建立。伺服器會依使用者儲存你的 Facturalia 正式 API 金鑰。付費方案（Pro、Pro+）透過 Stripe 結帳連結付款，取消後當期不退費。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Facturalia MCP by usefulapi，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。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.usefulapi%2Ffacturalia/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

README

Facturalia MCP by usefulapi

Use your Facturalia account from Claude, Cursor, or any MCP client. It reads the sent and paid status of invoices and the paid status of credit notes, and it creates live invoices and credit notes. Hosted, no local install: connect with your own credentials.

Live endpoint: https://facturalia.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://facturalia.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http facturalia https://facturalia.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "facturalia": {      "url": "https://facturalia.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Facturalia credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/facturalia/

On first connect you provide your Facturalia live API key (in Facturalia under Extra, Modules, API; it starts with fac_live_). The server validates it and stores it per user. No keys go in config files.
