概要

What is TimezoneToolkit?

TimezoneToolkit is an MCP (Model Context Protocol) server that provides advanced time and timezone tools, including conversion, current time, sunrise/sunset and moon phase calculations, countdowns, business day counts, and date formatting. It integrates with any MCP‑compatible client such as Claude Desktop, Cursor, Windsurf, Cline, or Roo Code.

How to use TimezoneToolkit?

Install with npx -y @cicatriz/timezone-toolkit@latest or via npm. Add the server configuration to your MCP client’s settings file (e.g., claude_desktop_config.json) using the command npx -y @cicatriz/timezone-toolkit. Optionally run the RESTful API server with node server.js to access tools over HTTP.

How do I install and configure TimezoneToolkit?

You can run it with `npx -y @cicatriz/timezone-toolkit@latest`, install globally from npm, or clone and build manually. Then add the command to your MCP client’s settings file (e.g., for Claude Desktop use `claude_desktop_config.json`).

3

Can I use TimezoneToolkit without an MCP client?

Yes. You can start the REST API server with `node server.js`, which provides endpoints such as `/api/convert-time`, `/api/sunrise-sunset`, and more.
