Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@astronomy-mcp-server What is the current moon phase?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
MCP Server for astronomy data — ISS tracking, moon phases, NASA APOD, near-Earth objects, exoplanets, space weather, and upcoming events. No API key required.
