Astronomy Oracle

Overview

Astronomy Oracle is a Model Context Protocol server that provides astronomical catalog data and an observing session planner. It gives MCP-compatible AI assistants access to over 13,000 celestial objects from OpenNGC, letting models decide when to query the catalog and help plan observations.

The server runs locally on your machine via the npm package astronomy-oracle, installed with npx -y astronomy-oracle. It communicates with your MCP client over stdio and requires no authentication or credentials to get started. Version v0.1.0 is available now under the MIT license, with source code at gregario/astronomy-oracle on GitHub.

Astronomy Oracle is a Development category tool on mcp.site and works with all MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this project, claim your listing to verify ownership and keep information up to date.
