At a Glance & Executive Verdict
Astrodynamics MCP
Aerospace & Astrodynamics · Local stdio
Quality: 43/100 (Fair) | Auth: No auth required
N2yo
Aerospace & Astrodynamics · Remote HTTP/SSE
Quality: 49/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Astrodynamics MCP if you need specialized Aerospace & Astrodynamics tools running via a local process. Choose N2yo if your workspace requires Aerospace & Astrodynamics integration with remote web transport. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Astrodynamics MCP 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).
Astrodynamics MCP is categorized under Aerospace & Astrodynamics and uses a local stdio subprocess. In contrast, N2yo belongs to Aerospace & Astrodynamics using remote streaming HTTP/SSE transport. Select Astrodynamics MCP when you need capabilities focused on aerospace & astrodynamics and N2yo when you require tools for aerospace & astrodynamics.

get_positions
Track where a satellite is right now (or in the next few seconds): get its live latitude, longitude, altitude, and look-angles (azimuth/elevation) from an observer on Earth. Use this to answer "where is the ISS right now?" (NORAD id 25544) or to locate any satellite by NORAD id. Example: get_positi…
get_visual_passes
Find when a satellite will be visible to the naked eye overhead from an observer location (visual passes = bright, sunlit passes against a dark sky). Returns start/max/end times, elevation, azimuths, brightness magnitude, and duration. Use this for "when can I see the ISS pass over?" Example: get_v…
whats_above
List what satellites are currently above a location on Earth, within a given radius of the observer's zenith. Use this to answer "what satellites are overhead right now?" Optionally filter by category (e.g. 52 = Starlink, 18 = amateur radio, 1 = brightest). Example: whats_above({ lat: 40.71, lon: -…
