USNO Astronomy MCP

The USNO Astronomy MCP Server provides four tools to query astronomical data from the US Naval Observatory ephemeris. It allows agents to determine the timing and type of solar eclipses, calculate local eclipse circumstances at specific coordinates, retrieve moon phase dates, and find equinox and solstice times for any given year.
