Astronomy Oracle

Astronomy Oracle is an open-source Model Context Protocol (MCP) server designed for AI and LLM assistants that require accurate astronomical catalog data and deterministic sky calculations. It includes tools for object lookup, catalog search, and observing session planning based on a bundled copy of the OpenNGC catalog (covering 13,000+ deep sky objects). It ensures zero network dependency and prevents hallucinated astronomical data by running all calculations locally. Suitable for any application needing trusted astronomy data and sky visibility planning for both human users and AI assistants.
