概覽

AI 產生的概覽

將助理連接到 inv.bg 開票帳戶,可讀取發票、客戶、品項、付款與銀行資料,並建立客戶、品項和發票。

可以做什麼
  • 讀取帳戶、公司資訊、單據類型、號碼組、付款方式和免營業稅原因
  • 列出並檢視發票、客戶與客戶聯絡人、品項目錄及計量單位
  • 檢視付款、銀行帳戶、用於對帳的銀行交易、錢箱和匯率
  • 建立和更新客戶、建立品項,並建立草稿或已開立的發票
  • 將發票以電子郵件寄給收件人,並為發票登錄付款
適用情境
適合在 inv.bg 管理開票、希望助理直接回答未付款或應收發票問題、查詢客戶與付款,或不必開啟應用程式就能草擬發票和登錄付款的情境。
執行需求
以 URL 連線的遠端 MCP 端點,無需本機安裝。登入使用 OAuth,首次連線時需輸入 inv.bg API 權杖(位於設定 > 關於公司 > API 存取),依使用者儲存。免費方案每月 50 次工具呼叫,付費方案可提高上限。
安裝前請注意
寫入類工具會更動真實帳務資料:建立已開立發票會佔用下一個法定編號,且無法透過此伺服器復原;寄送發票郵件會立即送出且無法收回。登錄付款時即使分配失敗,付款仍會被記錄。inv.bg API 權杖屬於憑證。付費方案需付費,透過結帳連結訂閱,取消後當期不退款。

README

inv.bg MCP by usefulapi

Use inv.bg from Claude, Cursor, or any MCP client — work with your invoices, clients, items, payments and bank transactions. Hosted, no local install: connect with your own inv.bg credentials.

Live endpoint: https://inv-bg.usefulapi.io/mcp · Homepage: https://usefulapi.io/inv-bg

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://inv-bg.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http inv-bg https://inv-bg.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": {    "inv-bg": {      "url": "https://inv-bg.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 inv.bg credentials.

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

On first connect you'll enter your inv.bg API token (Settings > About the Company > API access). It is validated, stored per-user, and scoped to you — no keys in config files.
