概覽

AI 產生的概覽

託管的 smallinvoice 連接器,讓助理讀取聯絡人、發票、報價、專案與工時,並可建立聯絡人和發票。

可以做什麼
  • 查看已連接帳戶的擁有者與連線狀態
  • 列出並讀取聯絡人、其地址、聯絡人與聯絡人群組
  • 列出並讀取發票及其明細、合計與已記錄付款
  • 列出並讀取報價、訂單確認與送貨單
  • 列出目錄中的產品、服務、單位與銀行帳戶
  • 列出專案、工時、費用、活動與成本單位
適用情境
適合讓助理回答 smallinvoice 帳戶相關問題,例如哪些發票尚未結清、誰欠款最多、各專案上月記錄了多少工時,並在不開啟應用的情況下草擬新聯絡人或發票。
執行需求
遠端 MCP 端點,僅需加入 URL;透過 OAuth 使用 smallinvoice 憑證登入,用戶端設定中不需要 API 金鑰或 Authorization 標頭。需要 smallinvoice 帳戶,免費方案每月允許 50 次工具呼叫。
安裝前請注意
有兩個寫入工具:建立聯絡人與建立發票,後者不具冪等性,重複呼叫會產生第二張發票;建立的發票不會寄給任何人。伺服器還提供付費方案(Pro 與 Pro+),附 Stripe 付款連結與取消訂閱工具,因此可能在對話中產生付費。smallinvoice 憑證需在提供者的登入頁輸入。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 smallinvoice 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。

smallinvoice MCP by usefulapi

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

Connect

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