Example

YOU SAY TO YOUR AGENT

List confirmed exoplanets within 20 pc that sit in the habitable zone.

On the right: the call your agent makes and the reply it got on 2026-10-13, shortened to the first records and a few of their fields.

search_exoplanets({
  "max_distance_pc": 20,
  "in_habitable_zone": true,
  "limit": 5
})

{
  "summary": "5 confirmed exoplanets within 20 pc (limit 5 reached; more may exist), sorted by distance. Habitable-zone filter is approximate: insolation 0.25–1.7 times Earth, which ignores the star type and the planet atmosphere. Source: NASA Exoplanet Archive.",

Frequently asked questions

Your agent calls lookup_astro_object, search_exoplanets, query_gaia over MCP. ScholarMuse queries NASA Exoplanet Archive, Gaia Archive, SIMBAD and returns records, each with its source, licence and a link you can check.

No. It costs 1 credit per call, charged only when the call succeeds. A new account gets 50 credits once, valid for 30 days.

Claude, ChatGPT, Codex, Cursor, Gemini CLI and any other client that supports MCP.

Yes. The same tools (lookup_astro_object, search_exoplanets, query_gaia) are available over the REST API.
