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

heart

heart_cast

Deterministically cast a YOWAYOW Mind-Key hexagram from six evidence-grounded root/body/outcome positions. Use after an autonomous agent has researched a concrete action choice, structural diagnosis, experiment, or macro-structure question. Submit current facts and their manifestation verdicts; never submit yin/yang lines or a desired hexagram. The tool returns cast_ready, needs_evidence, or out_of_scope. It uses no LLM, no random/time casting, and never falls back to traditional liuyao. Do not use for fortune, luck, hidden facts, random outcomes, or as a substitute for high-stakes professional judgment.

heart_fit

Use this zero-AI preflight before heart_cast when the original question is ambiguous or unstructured. It rejects ordinary fact lookups, pure prophecy, fortune, hidden facts, traditional liuyao, and high-stakes professional replacement. It returns research_required, needs_detail, or out_of_scope, plus the autonomous agent's next step. A needs_detail response means the agent should extract or research objective, options, constraints, success criteria, and current evidence; it does not require a human reply when authorized sources are available.

YOWAYOW Mind-Key Decision — questions

Answers built from our own checks of this server.

What can YOWAYOW Mind-Key Decision do?

It exposes 2 tools, read directly from the server on our last check. Among them: heart_cast, heart_fit. 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 →

Is YOWAYOW Mind-Key Decision 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 77 ms. The bar chart above shows every period we have measured.

How do I connect YOWAYOW Mind-Key Decision?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.

Does YOWAYOW Mind-Key Decision need an API key?

Yes. Every time we knock, YOWAYOW Mind-Key Decision answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is YOWAYOW Mind-Key Decision?

It answers our handshake in 77 ms on average, which is faster than 90% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
