iching-liuyao

六爻纳甲 (I Ching with LiuYao) MCP server. Deterministic. No LLM drift.

Rule-based Chinese metaphysics calculation engine — same inputs, same outputs. Pay-per-call via x402 USDC on Base. First 3 calls free per UA.

This package is a thin shim over xuanxue-bazi-matching, pre-filtered to expose: liuyao_yijing ($0.02/call).

Why deterministic, not LLM-based?

Chinese divination is a date conversion + lookup table problem. LLMs hallucinate the day pillar when crossing midnight, invent shen-sha (神煞) names, and silently apply wrong solar-term cutoffs. We solve this with a real rule engine.
