Horizons Nasa

Connects Claude to NASA's JPL Horizons system for querying solar system body positions and trajectories. Exposes four tools: lookup to resolve object names to SPK identifiers, ephemeris for generating position tables, and convenience wrappers for observer and vector table types. Useful when you need precise celestial coordinates, orbital data, or want to calculate positions of planets, asteroids, comets, or spacecraft at specific times. Hosted by Pipeworx as a streamable HTTP endpoint, so no local setup required. Can be used standalone or as part of the larger Pipeworx gateway with 673+ data sources. Includes an ask_pipeworx natural language interface that handles tool selection automatically.
