Astrology from a real ephemeris: natal charts, transits, synastry, eclipses, returns. No API keys.
Auseklis Astrology MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. Astrology from a real ephemeris: natal charts, transits, synastry, eclipses, returns. No API keys.
Named after the Latvian morning star. MIT-licensed with no AGPL ephemeris data — see Licensing.
Once Auseklis Astrology is connected, these are the calls the assistant has available:
get_planet_position — Position of one body/point at a moment (sign, degree, speed, retrograde)compute_natal_chart — Full birth chart: 13 points, houses, angles, Part of Fortune, aspectscompute_transits — Aspects from the current (or any) sky to a natal chartcompute_progressions — Secondary progressions (day-for-a-year)compute_synastry — Cross-chart aspects between two peoplecompute_composite_chart — Midpoint composite chart of a relationshipfind_returns — Solar/lunar/planetary returns (exact moments)get_moon_phase — Phase, illumination, Moon sign, next four quartersfind_eclipses — Lunar/solar eclipses with signs, incl. local visibilityfind_retrograde_periods — Station retrograde/direct moments for any planetfind_sign_ingresses — When a body changes signs (equinoxes, Saturn ingresses, …)find_aspect_times — Exact moment a transit perfects ("when does Saturn square my Sun?")Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
You will need one environment variable: MCP_SHARED_SECRET. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Auseklis Astrology's toolset — get_planet_position, compute_natal_chart, compute_transits and 9 more — is a fair guide to whether it matches your workflow. It is maintained by igmizo; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
