mcp-server-panchangam 1.10.4

MCP server for Panchangam calculations — Tithi, Nakshatra, Yoga, Muhurtas for any city

mcp-server-panchangam

An MCP (Model Context Protocol) server that gives AI assistants accurate Telugu/Vedic Panchangam data — Tithi, Nakshatra, Yoga, Karana, sky events, auspicious windows, Gochara, and planetary sky phenomena — for any city and date.

Installation

This is a standard MCP stdio server (uvx mcp-server-panchangam), compatible with any MCP client — Claude Desktop, Claude Code, Cursor, Windsurf, and custom agents built on the MCP SDK.

Claude Desktop — add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "panchangam": {
      "command": "uvx",
      "args": ["mcp-server-panchangam"]
    }
  }
}

Claude Code — run once:

claude mcp add panchangam -- uvx mcp-server-panchangam

For other MCP clients, point them at the same uvx mcp-server-panchangam command.

Tools

Tools are grouped by purpose. All tools that accept a city name also accept latitude, longitude, and timezone as an alternative.

Daily Panchangam

get_panchangam(date, city, system="drik", ayanamsa="lahiri", ...)

Full Panchangam for a date and city:

• Metadata — Samvatsara, Ayanam, Rituvu, Maasam, Paksham, Vaaram, solar and lunar signs
• Pancha Anga — Tithi, Nakshatra, Yoga, Karana with start/end times

• Auspicious windows — Brahma Muhurta, Abhijit Muhurta, Amrita Kalam
• Inauspicious windows — Rahu Kalam, Gulika Kalam, Yamagandam, Varjyam, Durmuhurtham
• Choghadiya — 8 day blocks with names
• Festivals — 30+ named Telugu festivals with traditional deciding moments (madhyahna/aparahna/pradosha/nishita), plus monthly Sankashti Chaturthi and Masa Shivaratri
• Special day flags — Ekadashi, Amavasya, Pournami, Pradosham, Sankranti, Ganda Moola
• Eclipse — Solar/lunar eclipse with type, visibility from your location, eclipse window, and Sutak period
• Special Yogas — Sarvartha Siddhi, Amrita Siddhi, Visha, and Dagdha yogas
• Timing fields — ghati_clock, nakshatra_pada, vishaghati, bhadra_mukha/bhadra_puchha, sankramana_avoidance, in_panchaka_nakshatra, nakshatra_mukha, anandadi_yoga, is_khar_maasa, is_pitru_paksha, simha_stha_guru/simha_stha_shukra, guru_maudhya/shukra_maudhya, disha_shoola_direction, panchaka_rahita

get_muhurta(date, city, system="drik", ...)

Auspicious and inauspicious time windows only — a lighter call for quick "is this a good time?" queries. Same window data as get_panchangam without the full Pancha Anga detail. For ranked time slots across several days, use find_muhurta.

get_panchanga_shuddhi(date, city, system="drik", ...)

Five-limb purity verdict for a date: counts how many of the five Panchangam limbs are auspicious (0–5) and returns a verdict from Sarva Ashuddha to Sarva Shuddha, with quality (shuddha / ashuddha / mixed) and a one-line reason for each limb. Values taken at sunrise.

Rules applied per limb:

• Tithi — Rikta tithis (4th, 9th, 14th of either paksha) are ashuddha
• Vaara — Mon/Wed/Thu/Fri are shuddha; Sun/Tue/Sat are ashuddha
• Nakshatra — Laghu/Mridu/Dhruva/Chara are shuddha; Tikshna/Ugra are ashuddha; Krittika/Vishakha (Mishra) are mixed
• Yoga — 17 Nitya auspicious yogas are shuddha; Vyatipata/Vaidhriti are ashuddha; six partial-dosha yogas are mixed (with dosha window in minutes)
• Karana — Vishti (Bhadra) and the four fixed karanas are ashuddha; all movable karanas are shuddha

Planning across days

get_panchangam_range(start_date, end_date, city, system="drik", ayanamsa="lahiri", ...)

Compact Panchangam summary for each day in a range (max 31 days): Tithi, Nakshatra, Yoga, sunrise/sunset, all auspicious and inauspicious windows, eclipse (if any), special yogas, and special-day flags. Useful for comparing multiple days or planning muhurtas across a week.

get_special_days(year, month, city, system="drik", ...)

Lists all special days in a given month: named festivals, Ekadashi, Amavasya, Pournami, Pradosham, Sankranti, Ganda Moola, and Solar/Lunar Eclipses, each with its special-yoga list.

find_muhurta(start_date, days=7, activity="any", city, system="drik", ayanamsa="lahiri", janma_nakshatras=None, ...)

Ranked auspicious time slots: good Choghadiya blocks (Amrit/Shubh/Labh/Char) with every inauspicious window subtracted, scored with Abhijit/Amrita overlap and special-yoga bonuses. Each slot carries its reasons.

activity tunes the rules for: travel, ceremony, purchase, beginning, litigation, cremation, construction_roof, wood_cutting, well_digging, coronation, or any. Optional travel_direction (N/S/E/W/NE/NW/SE/SW) activates Disha Shoola filtering. Optional birth stars (janma_nakshatras) keep only days whose Tarabalam favours everyone; optional janma_rasis add Chandrabalam. Activity-aware filters — Bhadra Mukha, Khar-Maasa, Adhika Maasa, Pitru Paksha, Simha-Stha, Maudhya, and Panchaka Rahita — are applied automatically per activity.

find_tarabalam_days(janma_nakshatras, start_date, days=14, city, system="drik", janma_rasis=None, ...)

Tarabalam & Chandrabalam: pass 1–4 birth stars and get each day's tara per person (Janma/Sampat/Vipat/Kshema/Pratyak/Sadhana/Naidhana/Mitra/Parama Mitra) plus good_for_all_dates — days auspicious for everyone at once. Pass janma_rasis to also check Chandrabalam; chandra_mode controls how it affects good_for_all: stars (annotate only — default, matches classic tarabalam tables), puja_ok, or strict. Up to 60 days per call.

Sky events

These tools cover multi-day astronomical phenomena that don't appear in the single-day Panchangam view.

get_combustion_calendar(start_date, end_date, city, planets=None, ...)

Asta (heliacal setting / combustion entry) and Udaya (heliacal rising / re-emergence) periods for the five classical planets — Mercury, Venus, Mars, Jupiter, Saturn — over a date range. Asta marks when a planet becomes invisible due to Sun proximity; Udaya marks when it re-emerges. Matches the sky-visibility criterion used by Drik Panchang's Asta/Udaya calendar. Max range: 366 days. planets accepts a subset (e.g. ["Saturn", "Jupiter"]).

get_graha_yuddha(start_date, end_date, planets=None)

Graha Yuddha (planetary war) periods: when two of the five tara grahas come within 1° of each other in ecliptic longitude. The planet with the higher ecliptic latitude at closest approach is the victor. Returns winner, loser, start/exact/end times in UTC, and minimum separation in arc-minutes. Sun, Moon, Rahu, and Ketu are exempt by classical convention. Max range: 366 days.

get_rashi_ingresses(start_date, end_date, planets=None, ayanamsa="lahiri")

All rashi (sign) ingress events for the classical planets: when a planet crosses from one zodiac sign to the next, including retrograde re-entries. Sidereal (Lahiri) throughout. Each entry includes the rashi entered, entry time (UTC), and exit time (next ingress). Moon is excluded (changes signs every ~2.25 days). Supported planets: Sun, Mercury, Venus, Mars, Jupiter, Saturn, Rahu, Ketu. Max range: 366 days.

get_eclipse_calendar(start_date, end_date, city, ...)

All solar and lunar eclipses in a date range with per-city visibility and Sutak timing. Each entry includes type (Solar/Lunar), subtype (Total/Annular/Partial/Penumbral), visibility from the given city, eclipse window in local time, and Sutak period (12h before Solar, 9h before Lunar) for visible eclipses. Max range: 730 days.

Gochara and personal transits

get_graha_positions(date, city, ayanamsa="lahiri", ...)

Sidereal (Lahiri) positions of all nine grahas at sunrise: longitude, rasi, nakshatra, pada, retrograde flag, plus rasi_until and next_rasi — when each graha next changes sign. Transit groundwork for gochara queries.

get_gochara(date, janma_rasi, city, ayanamsa="lahiri", ...)

Gochara (transit) verdicts from a janma rashi (natal Moon sign): each graha's house position counted from the janma rashi with a verdict — favourable, blocked (vedha, with the obstructing graha named), or adverse — per classical Brihat Samhita tables. Includes named conditions: Sade Sati (with phase), Ashtama Shani, Ardhastama Shani.

get_rasi_phalalu(date, janma_rasi, city, janma_nakshatra=None, ayanamsa="lahiri", ...)

Deterministic daily reading for a janma rashi, rendered entirely from computed facts: the Moon's Chandrabalam house sets the day quality, each graha's gochara verdict (with vedha) becomes one traceable sentence, Sade Sati/Ashtama Shani are stated when active, and passing janma_nakshatra adds the day's Tarabalam line. Every sentence maps to a calculation.

---

Intraday timing

get_daily_horas(date, city, system="drik", ...)

24 planetary hours (horas) for a date and city: 12 daytime horas starting at sunrise and 12 nighttime horas starting at sunset, each ruled by one of Sun/Moon/Mars/Mercury/Jupiter/Venus/Saturn. The first hora of the day is ruled by that weekday's lord (Sunday → Sun, Monday → Moon, …).

get_lagna_transitions(date, city, system="drik", ...)

Ascendant (Lagna) sign boundaries for the day — the rising sign on the eastern horizon, tracked from sunrise to next sunrise. Each entry includes start time, end time, and rashi name. Combined with get_daily_horas, gives the two classical intraday subdivisions used in Muhurta selection.

Utility

list_supported_cities()

Returns the 22 pre-configured cities with name, latitude, longitude, timezone, and country. Call this first to discover valid city names and spellings.

---

Cities and locations

city accepts any of the 22 pre-configured cities (resolved instantly, no network) or any free-text city name (geocoded via OpenStreetMap). You can also bypass city lookup by passing latitude, longitude, and timezone directly.

Telugu Heartland — Hyderabad, Vijayawada, Visakhapatnam, Tirupati, Warangal, Guntur, Nizamabad, Rajahmundry, Kurnool, Nellore

Major Indian Metros — Bengaluru, Chennai, Mumbai, Delhi

International Diaspora — Dallas, San Jose, San Francisco, Edison (NJ), New York, London, Sydney, Dubai

Calculation systems

System	Basis	Best for
drik	Swiss Ephemeris (pyswisseph) — ayanamsa-configurable	Modern apps, accurate sky events
surya_siddhanta	Mean-motion algorithms from the classical SS text	Traditions rooted in classical siddhantic calculation
vakya	Surya Siddhanta + published correction tables	Traditional Telugu/Tamil printed Panchangams

Ayanamsa

The Drik engine supports four sidereal ayanamsas via the ayanamsa= parameter:

Key	System
lahiri (default)	Lahiri / Chitrapaksha — the standard for modern Indian Panchangams
raman	B.V. Raman ayanamsa
krishnamurti	KP ayanamsa (Krishnamurti Paddhati)
true_chitrapaksha	True Chitrapaksha (star-based, not mean)

Tools that accept ayanamsa: get_panchangam, get_panchangam_range, find_muhurta, get_graha_positions, get_gochara, get_rasi_phalalu, get_rashi_ingresses.

Surya Siddhanta and Vakya use their own mean-motion models and ignore this parameter (accepted for API symmetry, no effect on output).
