概览

AI 生成的概览

离线 MCP 服务器，为助手提供 200 多个国家和地区的公共假日与工作日计算，并按当地周末规则判断。

可以做什么
  • 查询某国或某地区某年的公共、银行及可选假日，含英文与本地名称和补休日
  • 判断某日期在某国是否为工作日，并给出上一个和下一个工作日
  • 在日期上加减工作日，或统计两个日期之间的工作日数
  • 找出多个国家同时都是工作日的日期
  • 列出支持的国家代码及其州或地区代码
适用场景
适合跨国家安排日程时使用：分布式团队的会议日期、物流预计到达时间、合同或付款截止日、SLA 到期日、薪资、发货截单日以及市场休市日。当助手需要可靠的当地周末与假日规则而不是凭猜测给出日期时，它很有用。
运行要求
通过 stdio 在本地运行，通常用 npx 启动 npm 包 @appmonster/mcp-world-calendar，因此需要 Node.js。未声明任何 API 密钥或环境变量，README 称可离线使用。README 还提到一个托管 HTTP 端点。
安装前请注意
该服务器只读取日历数据，未声明任何凭据，风险较低。假日数据来自第三方数据集，可能未反映临时的政府调整，关键截止日期请自行核实。README 还提到托管端点，若使用该端点，查询会发送给第三方而非在本地运行。

安装

在 SourceWeft 中

  1. 打开 控制台中的 World Business Calendar，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。
