Jewish-Utilities
Miscellaneous utility skills for Jewish users — shabbat times, zmanim, parsha-of-the-week, hebrew date conversion, upcoming holidays, and daf yomi. Wraps the hebcal MCP server and complements jewish-texts-reference for full-text Sefaria lookups.

Dependencies
-
zmanim-mcp-server (recommended for zmanim and shabbat-times) — Python MCP using python-zmanim / KosherJava with NOAA-based astronomical calculations and GR"A + MG"A opinion support.
claude mcp add zmanim -- uvx zmanim-mcp-server
-
hebcal MCP server — calendar/holiday/parsha/daf-yomi/date-conversion tools (mcp__jungle-shared__hebcal__*). Fallback: the public hebcal REST API (https://www.hebcal.com/home/195/shabbat-times-rest-api).
-
jewish-texts-reference plugin (optional, recommended) — inline Tanakh/Talmud/Mishnah text via Sefaria, instead of link-outs.
Related tools & references
These aren't required dependencies — they're tools the skills reference, recommend, or could be extended with:
- hebcal/hebcal — the upstream open-source Hebrew calendar engine that backs the hebcal MCP.
- simlist/pyluach — Python Hebrew-calendar arithmetic; used as offline fallback in
hebrew-date-convert.
- Shmulik-Kravitz/jewish-date — TypeScript Hebrew-date library; recommended when the user is building a JS/TS app.
- torahcalc/torahcalc — Torah calculator (gematria, biblical units, dates). Useful reference; could be wrapped in a future
gematria skill.
- abe-101/myHebrewDates — Django app for tracking yahrzeits and Hebrew-date birthdays/anniversaries. Reference for users who want a hosted reminder service.
- subalterngames/talmudifier-rs — Rust tool that formats text in classic Talmud-page layout (with commentary columns). Relevant if rendering study sheets.
Data storage
Per-user config (location, candle-lighting offset, havdalah method, nusach) is stored at:
${CLAUDE_USER_DATA:-${XDG_DATA_HOME:-$HOME/.local/share}/claude-plugins}/jewish-utilities/config.json
Nothing is written to ~/.claude/plugins/jewish-utilities/ (that directory is replaced on plugin update).
