GEOMETRY answers date-keyed questions with fixed, structured JSON. Pass any Gregorian date — an event, a holiday, a historical day, or a birthday — and you get the same structured answer every time. Connect once over MCP; Claude Code, Claude Desktop, ChatGPT, Codex, Cursor, VS Code, and other clients can call it mid-conversation.
Prefer Claude for natural-language asks — enable once and stay in the thread. ChatGPT uses the same URL; use @geometry Call get_…, and start a new chat if the tool drops — quirks.
Ask for a Cosmic card, a cultural year, a moon phase, a season, or active retrogrades — you get the same result every time for the same date.
