Deterministic first
Pillars, solar terms, palaces, stars, and hexagrams are computed in code—not guessed by a language model.
Official open-source MCP by BaziWei
A deterministic Chinese metaphysics calculator built for AI agents. It computes solar terms, pillars, palaces, stars, and divination charts so the model can focus on understanding, reasoning, and expression.
No install or account required. Connect from any client that supports Remote MCP / Streamable HTTP.
Why Mingpan
Mingpan is not another fortune-telling bot. It supplies reproducible chart facts and leaves contextual, human interpretation to the AI you choose.
Pillars, solar terms, palaces, stars, and hexagrams are computed in code—not guessed by a language model.
The official service is stateless and does not store or cache birth inputs or chart results.
Source, dependencies, and tests are public so developers and researchers can inspect the calculation conventions.
18 Tools · One Endpoint
Every tool returns structured text designed for AI consumption. Mingpan deliberately avoids fortune scores, pattern verdicts, and life conclusions.
Four pillars, ten gods, hidden stems, na yin, growth stages, decade luck, and annual, monthly, and daily cycles.
Twelve palaces, major and auxiliary stars, four transformations, five-element bureau, and multi-level timing cycles.
Primary and transformed hexagrams, Najia, six relatives, six spirits, host/guest lines, void, and hidden spirits.
Time- or number-based casting with primary, mutual, transformed hexagrams and body–function relations.
Derives calendar primitives from Gregorian time and returns the heaven–earth plate, four lessons, three transmissions, and generals.
Multiple chart styles and intercalation methods, with the nine-palace chart and deterministic yong-shen facts by subject.
Plus 2 calendar primitives: precise times for the 24 solar terms and Gregorian–lunar conversion.

Mingpan × BaziWei
Mingpan is an independent, open-source calculation foundation. BaziWei connects subject management, BaZi and Zi Wei, AI readings, calendars, and sharing into a complete product. They complement each other without forcing the same school of interpretation.
