GEOMETRY MCP MCP server
Provides deterministic, pre-computed JSON data for calendars, moon phases, seasons, and astrological retrogrades for dates between 1900 and 2100. It ensures AI agents receive identical, non-drifting date facts across multiple runs, supporting RAG applications and deterministic AI behavior.
