Vedaksha
arthiq-labs/vedakshaAstronomical ephemeris and Vedic astrology (Jyotish) engine, written in Rust and exposed as 17 MCP tools: natal charts, panchanga, Vimshottari dashas, vargas, transits and transit search, muhurta search, ashtakavarga, shadbala, karakas, combustion, drishti, bhavas, synastry and composite charts. Runs locally over stdio. No network calls, no telemetry, no API keys and no configuration. **Install:** `cargo install vedaksha-mcp` then `vedaksha-mcp --stdio`, or `docker run --rm -i ghcr.io/arthiqlabs/vedaksha-mcp:v7.2.0 --stdio` (amd64 + arm64). Positions come from a clean-room implementation of VSOP87 and ELP/MPP02, with optional JPL SPK kernels, validated against JPL Horizons on a committed 24,350-row fixture; the SPK path agrees to 0.103 arcsec. Eleven sidereal ayanamsha systems are each derived forward from a primary source rather than tuned to match another implementation, and the derivation for each is recorded in the repository. **Licence:** BUSL-1.1 (source-available). Free for any non-commercial use. Commercial use is a one-time USD $500 per organisation. Each version converts to Apache-2.0 four years after its release.

Compute Vedic dasha (planetary period) sequences. Supports eight classical systems: Vimshottari, Ashtottari, Yogini (Moon-longitude based, require `moon_longitude`); Chara, Narayana (sign based, requi…
Compute Jaimini Chara Karaka assignments from sidereal planet longitudes. Ranks planets by degrees within their current sign: highest = Atmakaraka (soul significator), lowest = Darakaraka (spouse sign…
Compute combustion state for each planet relative to the Sun: principle per BPHS Ch.7 vv.28-29, orbs per Surya Siddhanta IX.6-8 and X.1 (Moon 12, Mars 17, Mercury 14 or 12 retrograde, Jupiter 11, Venu…
Compute the complete six-fold Shadbala of the seven grahas (Sun to Saturn) for a birth moment and place, per BPHS Ch.27, with Ishta and Kashta Phala per Ch.28, in virupas. Pass the moment and the plac…
Compute Vedic divisional charts (vargas). Given a time and place, returns one chart per requested division: the varga lagna, and for each of the ten bodies compute_natal_chart returns — the seven grah…
Turn a chart into a queryable property graph. Accepts the output of compute_natal_chart directly (pass latitude and longitude alongside it), or an existing ChartGraph. Emits Neo4j Cypher, SurrealDB Su…
Compute transiting planet positions relative to a natal chart at a specific moment. Returns planet longitudes for the transit time alongside natal positions, enabling aspect calculation between transi…
Search for transiting planet–natal planet aspects within a time window. Supply natal positions and a Julian Day range; receive a list of exact transit moments with aspect type, orb, and applying/separ…
Search for auspicious time windows (muhurta) within a given period for a geographic location. Returns ranked muhurta candidates with quality scores based on tithi, nakshatra, yoga, karana, and planeta…
Compute Bhinna Ashtakavarga (raw bindu tables) and Sarvashtakavarga for all 7 planets from sign positions. Source: BPHS Ch.66 vv.13-68. Trikona/Ekadhipatya Shodhana and Pinda Sadhana are not included.

Compute graha drishti — Vedic sign aspects — for all nine grahas. Unlike Western aspects, drishti is cast from sign to sign and is asymmetric: every graha aspects the 7th from itself, and Mars additio…
Compute the whole-sign bhava (house) chart from an ascendant. In the Vedic whole-sign system the entire sign containing the ascendant is the 1st bhava, the next sign the 2nd, and so on — houses do not…
Compute synastry — the aspects each graha in one chart makes to each graha in another chart. Every graha in chart A is tested against every graha in chart B (the two charts do not need the same graha …
Compute the midpoint composite chart of two charts: for each graha, the shorter-arc midpoint of its longitude in the two charts, and the arithmetic mean of its two speeds. The two charts must carry th…
