GenesisCore Astrology MCP server — Western + Vedic (Jyotish)

Free remote Model Context Protocol server for astrology calculations. No API key, no signup, no install.

Endpoint (Streamable HTTP, JSON responses): https://genesis-astro-guide-r2owtywexa-an.a.run.app/mcp

Ask your AI assistant things like "What is my moon sign? I was born 15 Aug 1995 at 06:30 in Pune", "What is my Vedic rashi and nakshatra?", "When is the next Mercury retrograde?" or "When does Mars enter Virgo?".

Tools

Tool	What it returns
`calculate_birth_chart_signs`	Sun to Pluto signs in the Western tropical zodiac and the Vedic sidereal (Lahiri) zodiac, Moon nakshatra, retrograde flags, and Ascendant / MC / Lagna when latitude and longitude are given
`get_retrograde_periods`	Mercury, Venus, Mars, Jupiter and Saturn retrograde and direct station times (UTC) with sign and degree, 2025–2027, and whether each is retrograde now
`get_sign_ingresses`	Exact UTC times Mercury, Venus or Mars entered each sign, 1940–2030
`get_current_sky`	Current tropical and sidereal positions of the Sun, Moon and planets

Every result includes links to plain-language explanation pages and a full_reading.app_url for a complete free Western + Vedic chart analysis on GenesisCore.
