Provides deterministic computation of magnetic declination and sky positions (sun, moon, planets) for any location and time, enabling agents to get accurate ephemeris and geomagnetic data without hallucination.
A local, open-source MCP server that wraps astronomy data services (SIMBAD, JPL Horizons, VizieR, etc.) behind a conversational interface, enabling AI assistants to answer astronomy questions with real, typed, and provenance-tracked data.
MCP server that provides tools to query 17+ astronomical databases (e.g., SIMBAD, VizieR, Gaia) via HTTP/TAP APIs, enabling AI applications to access astronomical data through natural language.
Provides authoritative astronomical data including moon phases, solar eclipses, and sun/moon rise and set times using the US Navy API or offline Skyfield calculations. It enables users to query Earth's seasons and celestial events for any location and date.
Provides unified natural language access to 40+ astronomical databases and surveys including DESI, SIMBAD, SDSS, and Gaia, enabling researchers to search, retrieve, and analyze astronomical data without learning complex APIs.
