Astronomy Oracle

Astronomy Oracle is an MCP-compatible server and toolkit designed for accurate astronomical catalog data and observing session planning for large language model (LLM) assistants. It provides deterministic astronomy math and bundled catalog data for over 13,000 deep-sky objects, allowing for fast, local computation of object lookups, catalog searches, and observing session planning—eliminating the possibility of hallucinated magnitudes, coordinates, or visibilities in AI outputs. Ideal for astronomy enthusiasts, educators, LLM developers, and anyone needing trusted astronomical data in their applications or AI agents.
