Astronomy Mcp Server

Overview

Astronomy Mcp Server brings offline observational astronomy into your AI assistant. It calculates celestial positions, sunrise and sunset times, moon phases, eclipses, and seasonal data—all without needing an internet connection during queries. As an MCP server, it exposes these capabilities as tools that Claude, Cursor, VS Code, and other AI clients can invoke directly.

Run Astronomy Mcp Server two ways: connect to the hosted endpoint at https://astronomy.caseyjhand.com/mcp for zero setup, or install locally via npx -y @cyanheads/astronomy-mcp-server and run on your own machine. No authentication required. The latest release is v0.2.9, distributed under the Apache-2.0 license with source code at cyanheads/astronomy-mcp-server on GitHub.

Astronomy Mcp Server is listed in the AI & Agents category and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain this server, claim your listing to earn the Verified badge and keep information up to date.
