Jpl Ssd vs Usno Astronomy
A side-by-side look at the Jpl Ssd and Usno Astronomy MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Jpl Ssd for aerospace & astrodynamics work as a local process; choose Usno Astronomy for aerospace & astrodynamics as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Jpl Ssd when
- You need dedicated capabilities in the Aerospace & Astrodynamics domain.
- You prefer a local stdio subprocess transport.
- You want tools like
get_small_body, close_approaches, impact_risk.
Choose Usno Astronomy when
- You need dedicated capabilities in the Aerospace & Astrodynamics domain.
- You prefer a local stdio subprocess transport.

Tools & capabilities
Jpl Ssd tools 4
get_small_bodyNASA/JPL Solar System Dynamics — look up an asteroid or comet by name or designation and return its orbit and physical parameters (eccentricity, semi-major axis, MOID, diameter, albedo, NEO/PHA flags). Keyless.close_approachesNASA/JPL CNEOS — list near-Earth close approaches to Earth in a date range, with miss distance (AU), relative velocity (km/s), and absolute magnitude (size proxy). Keyless.impact_riskNASA/JPL CNEOS Sentry — Earth impact risk for asteroids. Pass a designation for one object's cumulative impact probability, Palermo/Torino scale, diameter, and impact window; or omit it to list all currently-tracked objects above an impact-probability threshold. Keyless.recent_fireballsNASA/JPL CNEOS — most recent atmospheric fireballs/bolides detected by U.S. Government sensors, with date, radiated and total impact energy (kilotons of TNT), location, altitude, and velocity. Keyless.

Frequently asked questions
Jpl Ssd is categorized under Aerospace & Astrodynamics and uses a local stdio subprocess. Usno Astronomy belongs to Aerospace & Astrodynamics and uses a local stdio subprocess. Pick Jpl Ssd for aerospace & astrodynamics work and Usno Astronomy 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.
Jpl Ssd has no declared pricing — check the project's own site. Usno Astronomy 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 jpl-ssd and usno-astronomy as separate keys in the same mcpServers object, and your assistant will call tools from either one.
