About io.github.cyanheads/astronomy-mcp-server

io.github.cyanheads/astronomy-mcp-server is an MCP server in the Science category: offline observational astronomy: positions, rise/set, moon phases, eclipses, and seasons.

Install

Claude Code
claude mcp add io-github-cyanheads-astronomy-mcp-server -- npx -y @cyanheads/astronomy-mcp-server
npx
npx -y @cyanheads/astronomy-mcp-server

This server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

Tools (7)

astronomy_find_eventsForward search for the next occurrences of one sky-event class: eclipses, equinoxes, solstices, moon quarters, oppositions, conjunctions, greatest elongations, and apsides.

Parameters not published.

astronomy_get_ephemeris*(gated extension)* Time-series ephemeris for a small body (asteroid/comet) or spacecraft via JPL Horizons — covers what the in-process major-body set cannot. Off by default.

Parameters not published.

astronomy_get_moon_phaseMoon phase for an instant: illuminated fraction, phase name, synodic age, phase angle, and the next four quarter phases with timestamps.

Parameters not published.

astronomy_get_rise_setRise, set, and culmination times for a body at a location, with maximum altitude at transit. For the Sun, also the three twilight pairs (civil/nautical/astronomical).

Parameters not published.

astronomy_get_satellite_passes*(gated extension)* Visible passes of a satellite (by NORAD catalog number, or by a name resolved against the catalog) over an observer, from a CelesTrak GP element set propagated with SGP4 in-process. Off by default.

Parameters not published.

astronomy_get_sky_positionApparent position of one body or named star for an observer and instant — equatorial (RA/Dec), horizontal (alt/az), ecliptic, plus distance, magnitude, angular diameter, phase, and constellation.

Parameters not published.

astronomy_list_visibleThe one-call "what's up right now" answer: every naked-eye body (and optional bright stars) above the horizon, ranked, annotated, and gated by the Sun's altitude into daylight/twilight/dark.

Parameters not published.
