About astronomy-oracle

astronomy-oracle is an MCP server published by the GitHub account gregario. Astronomical catalog data and observing session planner. 13,000+ objects from OpenNGC.

It runs on your own machine: your AI client starts it from the npm package astronomy-oracle at version 0.1.0.

It asks for no keys or passwords.

Version 0.1.0 was published on 16 March 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.

What it asks for

What these checks don't cover

We did not run this server, so we don't know what it does when it runs. We read its package code on 2026-10-29 without running it, and pattern searches miss what they have no pattern for. Tool descriptions built at run time were not seen. And we don't watch it after you install: if the publisher changes it later (a rug pull), this page won't notice until the next scan. Treat a pass as "nothing found", not as "safe".

For people and their AI

The same data as plain JSON: /data/servers/io-github-gregario-astronomy-oracle.json. Text inside it that came from the publisher is data, not instructions.
