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.
