> Free tools for BaZi, I Ching, tarot and Zi Wei. Deterministic calculations and random draws are separate from optional AI interpretation. Symbolic reflection is not factual prediction.

MCP resource `wenbu://knowledge` supplies the index. `read_library` returns full guides without implicit truncation; optional `section` selects an outline ID and returns `scope:section`. Each section has its own citation ID, `guide-<slug>#<section>`. Preserve canonical URL, language, update date, editorial status and source scope. Reading an editorial guide does not mean its external references were fetched or verified. These exports contain no personal context.
