概覽

AI 產生的概覽

離線 MCP 伺服器，讓助理取得 200 多個國家與地區的國定假日與工作日計算，並依當地週末規則判斷。

可以做什麼
  • 查詢某國或某地區某年的國定、銀行與彈性假日，含英文與當地名稱及補假日
  • 判斷某日期在某國是否為工作日，並給出前一個與下一個工作日
  • 在日期上加減工作日，或計算兩個日期之間的工作日數
  • 找出多個國家同時都是工作日的日期
  • 列出支援的國家代碼及其州或地區代碼
適用情境
適合跨國安排時程時使用：分散式團隊的會議日期、物流預計到貨日、合約或付款截止日、SLA 到期日、薪資、出貨截止日以及市場休市日。當助理需要可靠的當地週末與假日規則，而不是憑猜測給日期時，它很有用。
執行需求
透過 stdio 在本機執行，通常以 npx 啟動 npm 套件 @appmonster/mcp-world-calendar，因此需要 Node.js。未宣告任何 API 金鑰或環境變數，README 表示可離線使用。README 另提到一個託管 HTTP 端點。
安裝前請注意
此伺服器只讀取行事曆資料，未宣告任何憑證，風險較低。假日資料來自第三方資料集，可能未反映臨時政府調整，關鍵截止日期請自行核實。README 另提到託管端點，若改用該端點，查詢會送往第三方而非在本機執行。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 World Business Calendar，將其新增到工作區。
