GEOMETRY MCP

Deterministic temporal reference data for AI builders — calendars, seasons, moon phases, planetary retrogrades, and traditional symbolic systems as stable JSON over Model Context Protocol.

Same date → same bytes, every time. No hallucinated dates. No wallet connect. No seed phrases.

This repository is the public docs + listing face for the hosted GEOMETRY MCP server. It is not the engine source, schema, or internal design docs.

Namespaces: Glama listing id app.geometry.mcp ≠ Official MCP Registry name app.geometry/mcp. Connect URL is always https://mcp.geometry.app/mcp.
