Description

TimezoneToolkit is a Model Context Protocol (MCP) server that exposes a set of tools for timezone conversion, current time lookup, sunrise/sunset and twilight calculations, moon phases, business-day math, countdowns, and flexible date formatting. It supports IANA timezones, multiple locales, and produces formatted human-readable outputs; it also includes a REST API for programmatic access. The server runs locally (Node.js) and emphasizes privacy by processing data locally. It is packaged for easy installation via npx or npm and integrates with MCP-capable clients like Claude Desktop and others.
