Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a database query by concatenation src/lib/account-client.ts:264

      delete temporary[kind + ':' + entry.id];

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

calculate

calculate_bazi

Calculate four pillars. Unknown time returns no hour pillar. Gregorian date, IANA timezone, explicit day boundary. No prediction.

calculate_ziwei

Calculate Zi Wei Dou Shu twelve palaces from an entered local civil date and known time. iztro default school, no solar-time correction. Sex is a traditional calculation parameter.

library

read_library

Read a complete Wenbu guide or symbol by search_library ID. Handbook guides return Markdown, outline and export links without truncation. Optionally provide a section ID from the outline; the returned scope makes partial reads explicit. A corrected stale citation returns source_superseded with a current-document read action, not withdrawn content or read evidence. External reference entries are metadata only; use your host browsing capability to verify them.

search_library

Search Wenbu original guides, symbols and curated reference metadata. This is a bounded catalogue, not a web search. Search snippets do not mean the source was read.

cast

cast_iching

Cast six three-coin lines or supply your own. Lines are ordered bottom to top, values 6/7/8/9. Returns original and changed King Wen hexagrams.

daily

get_daily_card

Get a public daily reflection card and practice using the server calendar in an IANA timezone. No model, account, personal history or quota turn. Can differ from a personal browser/account card. Keep the returned result for follow-up.

draw

draw_tarot

Draw one or three cards from a full 78-card deck without replacement. Reversals optional. Symbolic reflection only.

Wenbu · 问卜 — questions

Answers built from our own checks of this server.

What can Wenbu · 问卜 do?

It exposes 7 tools, read directly from the server on our last check. Among them: calculate_bazi, calculate_ziwei, cast_iching, draw_tarot, get_daily_card, read_library and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Wenbu · 问卜 mostly used for?

Its tools cluster around library and calculate. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Wenbu · 问卜 working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 416 ms. The bar chart above shows every period we have measured.

How do I connect Wenbu · 问卜?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Wenbu · 问卜 need an API key?

No. Wenbu · 问卜 completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Wenbu · 问卜?

It answers our handshake in 416 ms on average, which is faster than 30% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Wenbu · 问卜 open source?

The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at wenbu.app, which runs on its operator's own terms.
