Remote MCP server calculating BaZi, Zi Wei, tarot draws, and I Ching hexagrams. Connects via HTTP for free without account creation or API keys.

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.

- calculate Four Pillars (BaZi) charts adjusting for time zones
- generate twelve palaces for a Zi Wei chart from birth details
- cast I Ching hexagrams using the three-coin method
- draw one or three cards from a 78-card tarot deck without replacement

Does this MCP server require an API key?
No API key or registration is needed to connect to the remote endpoint. The service performs the calculations on Cloudflare, while your local AI client generates the explanation.
Can the agent read external reference links automatically?
