Celestrak vs Filesystem

A side-by-side look at the Celestrak and Filesystem MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

Tools & capabilities

Celestrak tools 3

  • get_satelliteGet satellite orbital elements (TLE / GP data) for a single object by NORAD catalog ID. Returns orbital parameters: inclination, eccentricity, mean motion, RAAN, argument of perigee, epoch, and derived orbital period in minutes. norad_id 25544 = ISS, 20580 = Hubble. This is the orbital catalog, not live position tracking.
  • search_by_nameSearch the satellite catalog by name substring and return matching orbital elements (TLE / GP data). e.g. "STARLINK", "NOAA", "GPS". Returns up to 50 matches with orbital parameters (inclination, eccentricity, period). Catalog/orbital data, not live tracking.
  • get_groupList orbital elements (TLE / GP data) for an entire CelesTrak group — e.g. the Starlink, GPS, or weather satellite catalog. Groups: "stations", "starlink", "gps-ops", "weather", "science", "geo", "active". Returns up to 100 satellites with orbital parameters (inclination, eccentricity, period). Catalog/orbital data, not live tracking.

Frequently asked questions

Celestrak is categorized under Aerospace & Astrodynamics and uses a local stdio subprocess. Filesystem belongs to File Systems and uses a local stdio subprocess. Pick Celestrak for aerospace & astrodynamics work and Filesystem for file systems.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

Celestrak is listed as free. Auth: no auth required. Filesystem is listed as free. Auth: no auth required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add celestrak and filesystem as separate keys in the same mcpServers object, and your assistant will call tools from either one.
