  • 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.

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. Jpl Ssd belongs to Aerospace & Astrodynamics and uses a local stdio subprocess. Pick Filesystem for file systems work and Jpl Ssd 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. Jpl Ssd 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 jpl-ssd 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 91,540 GitHub stars. Jpl Ssd has 51/100 (Good) with 1 views, 0 installs and 0 GitHub stars.
