## What it does

This server gives your AI assistant tools for traditional Chinese chart casting and reflective methods. The interface exposes seven operations: four pillars calculation (`calculate_bazi`), twelve palaces arrangement (`calculate_ziwei`), drawing from a 78-card tarot deck (`draw_tarot`), casting I Ching hexagrams (`cast_iching`), fetching a daily reflection card, and querying reference guides.

Setup runs remotely through Streamable HTTP at `https://wenbu.app/mcp`. The remote endpoint does not require an API token or a DeepSeek account, because your client LLM handles the actual interpretation of the returned data structures. If you run the repository locally, Node.js 22.12 or newer is required.

External reference queries return only URLs and metadata, so your agent must fetch those pages separately before citing them. By default, this MCP server communicates in English, which means you need to supply `locale: zh` if you need traditional Chinese output.
