In-depth architectural comparison of the Science and Tle MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Science
Aerospace & Astrodynamics · Remote HTTP/SSE
Quality: 56/100 (Good) | Auth: No auth required
Tle
Aerospace & Astrodynamics · Remote HTTP/SSE
Quality: 53/100 (Good) | Auth: No auth required
Verdict Summary: Choose Science if you need specialized Aerospace & Astrodynamics tools running via a hosted cloud SSE transport. Choose Tle 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 Science when:
You need dedicated capabilities in the Aerospace & Astrodynamics domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Fetch the International Space Station's current latitude, longitude, and Unix timestamp from the Open Notify API. No inputs required; returns a real-time position fix.
get_earthquakes
Retrieve up to 20 globally recent earthquakes from the USGS FDSN service, filtered by lookback period (1–30 days, default 1) and minimum magnitude (default 4.0). Returns magnitude, location name, depth (km), coordinates, time, and tsunami warning flag.
get_air_quality
Check current air quality at a latitude/longitude. Returns US AQI score and category plus PM2.5, PM10, ozone, NO2, and CO levels.
get_apod
Get NASA's Astronomy Picture of the Day with image URL, title, and explanation. Optionally specify a date (e.g., '2024-01-15').

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).
Science is categorized under Aerospace & Astrodynamics and uses a remote streaming HTTP/SSE transport. In contrast, Tle belongs to Aerospace & Astrodynamics using remote streaming HTTP/SSE transport. Select Science when you need capabilities focused on aerospace & astrodynamics and Tle when you require tools for aerospace & astrodynamics.
Fetch the Two-Line Element (TLE) set for a specific satellite by its NORAD catalog ID. Returns the satellite name, epoch date, and both TLE lines.
search_satellites
Search for satellites by name or keyword. Returns matching satellites with their NORAD IDs and TLE data.
list_recent
List the newest satellites in the NORAD catalog, highest catalog number first. NORAD ids are assigned in roughly launch order, so this approximates most-recently-launched. Note this orders by catalog entry, not by TLE epoch — the upstream offers no epoch-date sort.
