Give your AI assistant a 10,000-year almanac

Kaalshodh is a precision Indian-astronomy tool for AI assistants. Ask any assistant that speaks MCP about planetary positions, eclipses, conjunctions or historical panchang dates and it answers from JPL DE431 ephemeris tables spanning 5000 BCE to 5000 CE — computed, not guessed.

What you can ask

Questions large language models get wrong from memory — every answer here is a calculation.

Which planets are retrograde right now? Where was Saturn in 3102 BCE? When are Jupiter and Saturn next together in Aquarius? Solar eclipses over India in the 12th century An inscription reads Kartika Shukla 5, a Thursday, 1200s CE — which dates fit? Convert Vikram Samvat 1680 Kartik Shukla 5 to a Gregorian date When is the next Kumbh Mela?

Add to ~/.cursor/mcp.json:

{ "mcpServers": { "kaalshodh": { "url": "https://kaalshodh.com/mcp" } } }

VS Code (Copilot) ›

Add to .vscode/mcp.json:

{ "servers": { "kaalshodh": { "type": "http", "url": "https://kaalshodh.com/mcp" } } }

Gemini CLI ›

Add to ~/.gemini/settings.json:

{ "mcpServers": { "kaalshodh": { "httpUrl": "https://kaalshodh.com/mcp" } } }

Config field names vary a little by client and version — every client here connects to the same URL over Streamable HTTP.

Looking for daily panchang?

Kaalshodh is tuned for astronomy and deep history. For everyday Hindu-calendar answers exactly as the HinduCalendar app shows them — today's tithi, festival dates, muhurta, a birth chart — use its companion server:

HinduCalendar MCP →

Daily panchang, festivals, muhurta and kundali — app-identical. https://hinducalendar.app/mcp

The two run different engines and can differ by a minute or two near a tithi boundary: Kaalshodh to search history, HinduCalendar to match the app.

Privacy

Queries are computed in memory and answered from precomputed tables. No accounts, no sign-in. Nothing you ask — including any birth date, time or place — is stored or logged; server logs record only which tool ran and how long it took. Full details: privacy policy.
