In-depth architectural comparison of the Launches and Science 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
Launches
Aerospace & Astrodynamics · Local stdio
Quality: 51/100 (Good) | Auth: No auth required
Science
Aerospace & Astrodynamics · Remote HTTP/SSE
Quality: 56/100 (Good) | Auth: No auth required
Verdict Summary: Choose Launches if you need specialized Aerospace & Astrodynamics tools running via a local process. Choose Science 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 Launches 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).
Fetch the next scheduled rocket launches from Launch Library 2. Returns launch name, NET (no-earlier-than) time, status, launch pad, rocket type, and mission description. Default 10 results.
get_past_launches
Fetch rocket launches that have already flown, sorted newest-first, from Launch Library 2. `launches` holds only those with a confirmed outcome — successful, failed or partial failure — so counting them answers "how many launches happened". A launch whose scheduled time has passed but whose outcome…
get_launch
Get full details for a specific launch by ID. Returns name, time, status, pad, rocket, mission, orbit info, video links, and mission patches.
search_launches
Search launches by keyword (rocket name, mission, agency). Returns matching launches with name, time, status, pad, rocket, and mission.
Science Tools (4)
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).
Launches is categorized under Aerospace & Astrodynamics and uses a local stdio subprocess. In contrast, Science belongs to Aerospace & Astrodynamics using remote streaming HTTP/SSE transport. Select Launches when you need capabilities focused on aerospace & astrodynamics and Science when you require tools for aerospace & astrodynamics.
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').
