Does this need an API key?

No. Celestrak publishes its GP orbital elements openly, so this server works the moment you subscribe. Nothing to generate and nothing to paste.

Why do the same satellites come back unchanged when I ask again?

Celestrak refreshes orbital elements once every 2 hours. Requesting the same group inside that window returns a clear "not updated" message rather than new data — the elements you already have are still current. Wait about two hours before re-fetching.

How do I find one specific satellite?

Three ways: by NORAD catalog id (25544 is the ISS), by name ("STARLINK-1008", "ISS (ZARYA)"), or by international designator to get an entire launch at once (2019-074 returns the whole first Starlink launch). For a single satellite, name or id is far faster than paging the constellation.

Satellite Tracking MCP Connector for Claude

More Details Connect to Claude

Connect any AI agent to live satellite tracking — orbital elements for everything in Earth orbit, served from Celestrak's public GP data. No API key required.

What you can do

The Starlink constellation — every satellite SpaceX has put up, with live orbital elements
Space stations — the ISS and the rest of that group
Every active satellite — roughly 16,000+ objects
The brightest objects — the ~150 most likely to be visible during a pass
Recent launches — objects added to the catalog in the last 30 days
Single lookups — by NORAD catalog id, by name, or by launch (international designator)

Each result carries the full GP element set: epoch, inclination, period, apogee, perigee, eccentricity and the NORAD id.

How it works

Subscribe to this server — no account or key needed
Ask your agent: "Where is the ISS right now?", "How many Starlinks are in orbit?", "What did the first Starlink launch put up?"
Large groups paginate — the agent walks through with offset/limit

Celestrak refreshes orbital elements once every 2 hours. A repeat call inside that window comes back unchanged, which the server reports clearly rather than silently re-serving.

Who is this for

Space enthusiasts and educators — answer orbital questions from a chat instead of scraping TLE files
Ham operators and observers — plan passes from current elements
Analysts — count and inspect a constellation without writing a parser
Developers — prototype space apps with agent-driven element retrieval

8 tools expose this connector's capabilities to your AI agent.

get_satellite_by_intdes

"2019-074" returns the whole first Starlink launch; "2019-074A" returns only its first object. This is the fastest way to list everything a single rocket put up. Get every object from one launch by its international designator (e.g. 2019-074 = first Starlink launch)

get_satellite_by_name

A partial name can match many objects, so this returns all matches. If nothing matches, switch to the NORAD id with get_satellite_by_norad_id. Find satellites by name — e.g. "STARLINK-1008", "ISS (ZARYA)", "HST"

get_satellite_by_norad_id

If you have a name instead, use get_satellite_by_name. Returns one element set with epoch, inclination, period, apogee and perigee. Get the live orbital elements of one satellite by its NORAD catalog id (e.g. 25544 = the ISS)

list_space_stations

No pagination needed in practice. Elements refresh once every 2 hours at Celestrak; a repeat call inside that window says "not updated", which means your data is still current. List space stations and large orbital infrastructure — the ISS and the rest of that group — with live orbital elements

list_active_satellites

ALWAYS paginate with offset/limit rather than pulling it all into context. Start with limit=100 and increase offset to walk through. If the user wants one constellation or one launch, use list_starlink_satellites or get_satellite_by_intdes instead — this tool is for exhaustive coverage. Elements refresh once every 2 hours at Celestrak. List every active satellite in orbit — about 16,000+ objects, all with live orbital elements

list_brightest_satellites

This is the right starting point for "what can I see overhead tonight". The orbital elements here let you work out pass geometry; Celestrak refreshes them once every 2 hours. List the brightest satellites — the ones most likely to be visible to the naked eye during a pass

list_recently_launched_satellites

Useful for tracking a fresh launch before its objects spread out. Elements refresh once every 2 hours at Celestrak. List satellites launched in the last 30 days — newest objects in orbit

list_starlink_satellites

The constellation is thousands of satellites, so this tool paginates: pass offset to page through results, limit up to 500 per call. Celestrak refreshes these elements only once every 2 hours — a second call inside that window returns "not updated", which means the data you already have is current, not an error. To find one specific Starlink, use get_satellite_by_name with e.g. "STARLINK-1008" instead of paging the whole constellation. List the full Starlink satellite constellation with live orbital elements from Celestrak
