At a Glance & Executive Verdict
Nasa
Aerospace & Astrodynamics · Local stdio
Quality: 43/100 (Fair) | Auth: No auth required
Astronomy MCP Server
Aerospace & Astrodynamics · Local stdio
Quality: 53/100 (Good) | Auth: No auth required
Verdict Summary: Choose Nasa if you need specialized Aerospace & Astrodynamics tools running via a local process. Choose Astronomy MCP Server if your workspace requires Aerospace & Astrodynamics integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
N
Choose Nasa when:
You need dedicated capabilities in the Aerospace & Astrodynamics domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Get the NASA Astronomy Picture of the Day with explanation. Optionally specify a date. Example: get_apod({ date: "2024-01-15", _apiKey: "DEMO_KEY" })
get_asteroids
Get near-Earth asteroids approaching within a date range (max 7 days). Returns size, velocity, and miss distance. Example: get_asteroids({ start_date: "2024-01-01", end_date: "2024-01-07", _apiKey: "DEMO_KEY" })
get_mars_photos
"Show me photos from the Mars rover" / "Perseverance images from sol 1000" / "latest pictures from Mars" — raw images from NASA's Perseverance rover (Mars 2020), straight off the mars.nasa.gov feed. Filter by Martian sol and by camera. Returns image URLs at four resolutions, the sol, the UTC and Ma…
search_nasa_images
Search the NASA Image and Video Library for images/videos of any subject — planets, missions, astronauts, launches, galaxies, etc. PREFER for "NASA photos of Jupiter", "images of the Apollo 11 mission", "pictures of a nebula". Returns title, description, date, NASA ID, media type, and a thumbnail U…
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Nasa is categorized under Aerospace & Astrodynamics and uses a local stdio subprocess. In contrast, Astronomy MCP Server belongs to Aerospace & Astrodynamics using local stdio subprocess. Select Nasa when you need capabilities focused on aerospace & astrodynamics and Astronomy MCP Server when you require tools for aerospace & astrodynamics.
Get recent solar flare events from NASA DONKI space-weather data. Returns each flare's class (e.g. C4.0, M1.8, X1.2), begin/peak/end times, source region, and active region number. Use for "recent solar flares", "is there solar activity / a solar storm", space-weather questions.
Astronomy MCP Server Tools (7)
astronomy_get_sky_position
Apparent 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.
astronomy_get_rise_set
Rise, 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).
astronomy_get_moon_phase
Moon phase for an instant: illuminated fraction, phase name, synodic age, phase angle, and the next four quarter phases with timestamps.
astronomy_find_events
Forward search for the next occurrences of one sky-event class: eclipses, equinoxes, solstices, moon quarters, oppositions, conjunctions, greatest elongations, and apsides.
astronomy_list_visible
The 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.
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.
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.
