Is vedaksha-mcp live?

Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.

Is vedaksha-mcp free to use?

Yes — the hub reached it with no key and no payment.

What tools does vedaksha-mcp have?

17 tools: search_muhurta, compute_dasha, compute_karakas, compute_vargas, emit_graph, search_transits, compute_panchanga, compute_bhavas, ….

Is vedaksha-mcp safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• search_muhurta reads unknown 23h ago

  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 planetary positions. The search window is capped at 30 days (see MUHURTA_SEARCH_RANGE_TOO_LARGE), a scope limit; for a longer horizon, issue several searches.

• compute_dasha reads unknown never probed

  Compute Vedic dasha (planetary period) sequences. Supports eight classical systems: Vimshottari, Ashtottari, Yogini (Moon-longitude based, require `moon_longitude`); Chara, Narayana (sign based, require BOTH `lagna_sign` AND `graha_signs`, since each sign's period length is counted to the sign its lord occupies in this chart); Sthira, NiryanaShoola (`niryana_shoola` is accepted too) and Maheshwara (Jaimini rashi dashas, require `lagna_sign` AND `graha_longitudes`, since the atmakaraka and the tie-breaks of the strength tests read degrees). `graha_signs` takes the eight `sign_index` values compute_natal_chart already returns, `graha_longitudes` the eight sidereal longitudes; Ketu is derived from Rahu and must not be supplied. Yogini takes `rounds` (1 to 10 whole 36-year rounds) or `until` (a horizon Julian Day); Chara takes `antardashas` (twelve per period, BPHS 51.5-51.9). Sthira, NiryanaShoola and Maheshwara use the defaults of the vedic crate's dasha functions (see their module docs) and always carry their antardashas. Sthira and Maheshwara start from the Brahma graha; a chart whose marks leave none returns `no_brahma: true` with a message, not an error. Returns a JSON dasha tree with start/end Julian Days. For Vimshottari, Ashtottari and Yogini the first maha opens at birth with `initial_balance` of its length, but its sub-periods keep their full shares from the maha's notional start before birth: those with end_jd <= birth_jd ended before birth, and the one running at birth starts at or before it.

• compute_vargas reads unknown never probed

  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 grahas plus the mean, true and osculating lunar node — its rashi longitude, the sign it occupies within that varga, its dignity in that sign, and its whole-sign bhava counted from the varga lagna. Ketu is not listed separately: it is the node's opposite point, 180 degrees away. The nodes carry no dignity, so that field is absent for them. Supply planet_longitude instead to divide a single longitude without an ephemeris lookup, in which case no graha name, dignity or bhava is returned because none is defined. Vargas are classically read on a sidereal zodiac: pass an ayanamsha, or accept the Tropical default this surface uses everywhere. Source: BPHS Ch. 6-7.

• compute_panchanga reads unknown never probed

  Compute the panchanga — the five limbs of the Vedic almanac — for an instant: tithi (lunar day, with paksha and lord), vara (weekday reckoned from local sunrise, with its lord and the Rahu and Gulika Kalam windows as Julian Days), nakshatra (with pada), yoga (one of the 27 nithya yogas, with degrees remaining), and karana (half-tithi). Takes sidereal longitudes; all returned instants are Julian Days (UT). vara.from_sunrise reports HOW the weekday was reckoned: true means it was taken from an actual local sunrise (the Vedic definition); false means no sunrise exists to reckon from — the polar day or polar night, above about ±66.5° latitude — and the value is the observer's local CIVIL weekday as a documented fallback, which is a different quantity. Check it before presenting the vara at high latitude. vara.rahu_kalam being null is NOT the same signal: the Kalam windows can also be null while from_sunrise is true.

• compute_bhavas reads unknown never probed

  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 have cusps within signs. Returns the sign of each of the twelve bhavas with its kendra / trikona / dusthana / upachaya classification, and optionally places supplied grahas into their bhavas.

• compute_synastry reads unknown never probed

  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 names), and each hit is returned with its aspect type, orb in degrees and strength (1.0 at exact, falling linearly to 0.0 at the orb boundary). Orbs are the traditional Lilly values — conjunction, trine and opposition 8°, square 7°, sextile 6°, minors 2° — scaled by orb_factor. Longitudes only: this tool needs no birth time, place or ephemeris.

• compute_shadbala reads unknown never probed

  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 place; the tool casts the chart itself and reads sunrise, sunset and the next sunrise from the engine. Every part is in the output, each in its own field: Sthana (uccha, saptavargaja, ojhayugma, kendradi, drekkana), Dig (continuous, the arc from the weak cusp over 3, 27.7), Kala (nathonnata, paksha, tribhaga, abda, masa, vara, hora, ayana and yuddha, which is signed), Cheshta (the cheshta kendra for Mars to Saturn, the Sun's ayana and the Moon's paksha bala, 27.18 and 27.24-25), Naisargika and Drik (a quarter of the benefic sphuta drishti added, a quarter of the malefic taken away, the aspect of Mercury and Jupiter added whole, 27.19; it can be negative or pass 60). The Sun's ayana and the Moon's paksha bala are counted once in kala and once in cheshta, each undoubled. The rules are the verses' defaults; the benefic and malefic grahas are those of BPHS 3.11, with Rahu (the mean node) and Ketu counting only as malefic company for Mercury. Each graha also carries its motion state (vakra, anuvakra, ... atichara, 27.21-23) against the mean geocentric motion; it is reported beside the strengths and is not part of any total. The Sun must both rise and set at the place: in the polar day or night there is no Hindu day to divide into thirds and horas, and the call fails by name.

• compute_gochara reads unknown never probed

  Compute Gochara (transit interpretation) for the seven grahas against a natal reference sign per BPHS Ch.29. Returns favourable/unfavourable verdict, house from natal, and raw vedha (obstruction) candidates per planet. The natal reference sign is the caller's choice — typically the natal Moon's sign (Chandra Gochara) or the natal Lagna's sign. Rahu and Ketu are not included.

• compute_drishti reads unknown never probed

  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 additionally aspects the 4th and 8th, Jupiter the 5th and 9th, Saturn the 3rd and 10th. Returns each aspect with its graded strength (Full, ThreeQuarter, Half, Quarter) and the house distance.

• compute_combustion reads unknown never probed

  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, Venus 10 or 8 retrograde, Saturn 15 deg). Returns Combust, DeeplyCombust, or None for Moon, Mars, Mercury, Jupiter, Venus, Saturn with degrees of separation. This is a low-level tool over already-known positions, not a natal-chart tool: call compute_natal_chart first and pass its planets[].longitude (matched by planets[].name) and planets[].retrograde values straight through as this tool's inputs — do not recompute or re-derive them.
