Tools & capabilities

Mast Nasa tools 4

  • cone_searchSearch MAST around (RA, Dec).
  • mission_searchMission-scoped search with arbitrary criteria.
  • caomGeneric CAOM (Common Archive Observation Model) query.
  • lookup_nameResolve target name → coords.

Space Feeds tools 3

  • list_feedsList the curated space & spaceflight feeds (id, title, category, source). Optionally filter by category (space) or keyword. Pass an id to read_feed.
  • read_feedRead a curated space & spaceflight feed by its id (from list_feeds). Returns normalized items (title, link, published, summary). Optionally filter items by keyword.
  • fetch_feedFetch and normalize any RSS / Atom / RDF feed by URL. CF-robust: fetches directly and falls back to a proxy if the source blocks the gateway. Use list_feeds first for curated sources.

Ready-to-paste client configs
