Zmanim MCP Server
Wraps the python-zmanim library to calculate Jewish prayer times for any global location. Exposes six tools: get sunrise/sunset, latest Shema times, latest Tefila times, Mincha times, Shabbat candle lighting and Havdalah, plus a comprehensive daily schedule. All calculations use NOAA astronomical algorithms and support both GRA and MGA halachic opinions. You pass in coordinates, timezone, and optional date, then get back times in markdown or JSON. Useful if you're building Jewish calendar applications, scheduling tools, or need accurate zmanim calculations without implementing the astronomy yourself. Handles edge cases like polar regions gracefully and includes customizable candle lighting offsets.
