astronomy-mcp-server

Ingested from the official MCP Registry

FastDrop pulled this entry from the official MCP Registry as io.github.cyanheads/astronomy-mcp-server and probed the endpoint. The maker did not submit it, so the outbound link is not endorsed and the description is not theirs.

• astronomy_get_sky_position

  Compute the apparent topocentric position of one solar-system body (sun, moon, mercury through neptune, pluto) or a named bright star for an observer location and instant. Returns equatorial (RA/Dec),

• astronomy_get_rise_set

  Compute rise, set, and culmination (transit) times for a body at an observer location, plus the maximum altitude at culmination. For the Sun, also returns the three twilight pairs (civil −6°, nautical

• astronomy_get_moon_phase

  Report the Moon phase for an instant: illuminated fraction, phase name, synodic age in days since the new moon, phase longitude (the Moon–Sun ecliptic-longitude difference, 180° at full), and the next

• astronomy_find_events

  Search forward from a start time for the next occurrences of one sky-event class, selected by the `event` enum: solar_eclipse, lunar_eclipse, equinox, solstice, moon_quarter, opposition, conjunction,

• astronomy_list_visible

  The one-call "what is up right now" answer. For an observer location and instant, iterate every naked-eye solar-system body (and, with include_stars, the bundled bright stars), compute altitude and az

• astronomy_get_ephemeris

  Fetch a time-series ephemeris for a small body (asteroid or comet) or spacecraft from JPL Horizons — RA/Dec, distance, and apparent magnitude over a span, optionally with observer-relative altitude/az

• astronomy_get_satellite_passes

  Predict visible passes of a satellite (e.g. the ISS, NORAD 25544) over an observer in the next `days`. Identify the satellite by exactly one of `norad_id` or `name` — supplying both, or neither, is re
