Science tools 4

  • get_iss_locationFetch 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_earthquakesRetrieve 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_qualityCheck current air quality at a latitude/longitude. Returns US AQI score and category plus PM2.5, PM10, ozone, NO2, and CO levels.
  • get_apodGet 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 configs

Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.

Frequently asked questions

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

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.

Filesystem is listed as free. Auth: no auth required. Science has no declared pricing — check the project's own site. 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 filesystem and science as separate keys in the same mcpServers object, and your assistant will call tools from either one.

On AllMCPs, Filesystem has a quality signal of 85/100 (Excellent) with 11 views, 0 installs and 91,526 GitHub stars. Science has 51/100 (Good) with 1 views, 0 installs and 0 GitHub stars.
