mcp-server-panchangam 1.4.0

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, and auspicious/inauspicious time windows — for any city and date.

Installation

This is a standard MCP stdio server (uvx mcp-server-panchangam), so it works with any MCP-compatible client or agent — Claude Desktop, Claude Code, Cursor, Windsurf, and custom agents built on the MCP SDK. Below are examples for a couple of common clients; for others, point your client's MCP config at the same uvx mcp-server-panchangam command.

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

Tools

list_supported_cities

• Festivals — 30+ named Telugu festivals (Ugadi, Vinayaka Chavithi, Deepavali, Maha Shivaratri, Makara Sankranti cluster, Navaratri days, Varalakshmi Vratam, …) plus monthly Sankashti Chaturthi and Masa Shivaratri, with traditional deciding moments (madhyahna/aparahna/pradosha/nishita)

get_muhurta(date, city, system="drik", latitude=None, longitude=None, timezone=None)

Auspicious and inauspicious time windows only — a lighter call for quick "is this a good time?" queries.

find_tarabalam_days(janma_nakshatras, start_date, days=14, city="Hyderabad", system="drik", ...)

Tarabalam & Chandrabalam: pass 1-4 birth stars (e.g. ["Uttara Bhadrapada", "Purva Ashadha"]) 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. Optionally pass janma_rasis (aligned, null entries allowed) to also check Chandrabalam — each person then gets the Moon's position from their rashi with a verdict (good / needs remedial puja / avoid), and chandra_mode selects how it affects good_for_all: stars (annotate only — default, matches classic tarabalam tables), puja_ok, or strict. Up to 60 days per call.

get_graha_positions(date, city="Hyderabad", ...)

Sidereal (Lahiri) positions of all nine grahas at sunrise: longitude, rasi, nakshatra, pada, retrograde flag, plus rasi_until and next_rasi — the date each graha changes sign, retrograde-aware.

get_special_days(year, month, city, system="drik", latitude=None, longitude=None, timezone=None)

Lists special days in a given month: named festivals, Ekadashi (fasting), Amavasya (new moon), Pournami (full moon), Pradosham, Sankranti, Ganda Moola, and Solar/Lunar Eclipses. Each entry includes a special_yogas list for that day.
