BirthStar MCP server

• Addresshttps://mcp.birthstar.ai/mcpnot in the official registry: answered when asked

No entry in the official MCP registry names this server. It answered on birthstar.ai when the Atlas asked at the address servers are usually mounted on, so it is the vendor's own. Clients and catalogues that list servers from the registry do not show it.

On 2026-10-28 the server answered initialize and tools/list without a sign-in. First answer in 304 ms.

• Its tools do every use case we checked: check timing for career, marriage or money questions; compare two birth charts for partnership compatibility.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• create_chart

  Compute a full Vedic natal chart and cache it, returning a short handle. Call this FIRST. It returns a `chart_id` plus a small summary. Pass that chart_id to the other tools (get_grahas, get_houses, get_current_dasha, get_panchanga…

• get_grahas

  Get planetary positions for a cached chart. Args: chart_id: Handle returned by create_chart. planets: Optional list of names to fetch (e.g. ["Moon", "Saturn"]). Defaults to the 9 classical grahas. Also accepts the outer bodies Uranus…

• get_houses

  Get the 12 houses (bhavas) for a cached chart. Args: chart_id: Handle returned by create_chart. method: "whole_sign" (default) — sign, lord, lord placement, karaka, occupants. "bhava_chalit" — Sripati/Porphyry cusps with degree spans…

• get_dasha_periods

  Walk the dasha tree — list periods at any level, past or future. Use this for "when does my next antardasha start", "what runs after this mahadasha", "when was I in Jupiter". get_current_dasha only tells you what is running now; this…

• get_timeline

  Get the turning points between two dates — dasha changes and slow-planet ingresses. This is the two-clocks view: the dasha sequence counted from birth (which theme is switched on) against gochara, the real sky on that date (the trigger)…

• get_lagna_points

  Get the chart angles, special lagnas, Arudha padas and Bhrigu Bindu. Beyond the ascendant: MC/IC/Descendant/Vertex, the time-based special lagnas (Bhava/Hora/Ghati/Sree/Indu), the Jaimini Arudha padas (AL, A2-A12, Upapada) and Bhrigu…

• get_varga

  Get one divisional chart (varga) from a cached chart. Args: chart_id: Handle returned by create_chart. varga: Which divisional chart, e.g. "D9" (navamsa), "D10" (dashamsa), "D11", "D60". See describe_chart -> varga_coverage for the full…

• get_vimsopaka

  Get planetary avasthas — the maturity, alertness and mood states of each graha. Baladi is the age state (infant..dead) and scales a planet's ability to deliver. Jagradadi is awake/dreaming/sleeping. Deeptadi is the mood from exaltation…

• get_fixed_stars

  Get conjunctions between the grahas and named prominent fixed stars. Returns only real conjunctions within the configured orb, plus what was scanned. An empty `conjunctions` list is a provable negative, not a skipped check…

• get_longevity

  Get Ayurdaya (longevity) estimates — EXPERIMENTAL, not for predictive use. The engine computes Pindayu and Nisargayu, but flags the whole section experimental: the classical methods are textually divergent and the reduction rules are only…
