Ephemeris MCP gives AI agents astronomy-grade sky-position calculations using PyEphem. Query apparent RA/Dec and local altitude/azimuth for planets, the Moon, the Sun, and bright stars; calculate rise, set, and transit times; list visible planets from an observer site; and compute local sidereal time. It is useful for astronomy education, observing plans, science assistants, planetarium workflows, and space/sky-aware automations.
