Is yowayow-heart-decision free to use?
Yes — the hub reached it with no key and no payment.
What tools does yowayow-heart-decision have?
3 tools: heart_fit, heart_cast, liuyao_cast.
Is yowayow-heart-decision safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • liuyao_cast open 6h ago

    Use when the user explicitly requests traditional Liuyao casting, Najia, six relatives/spirits or Shi/Ying. Do not send it through heart_fit. auto reuses the App's casting-time plus secure random perturbation algorithm with three-coin probabilities; manual preserves six existing 6/7/8/9 values ordered bottom to top. Supply the user's IANA timezone and the original casting time when replaying a plate. Returns original/changed hexagrams, all moving lines, calendar, Najia, six relatives/spirits, Shi/Ying, void and seasonal facts. It uses no LLM and does not generate a report or fixed interpretation. Preserve a successful result rather than rerolling to obtain a preferred hexagram.

  • heart_fit reads unknown 6h ago

    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.

  • heart_cast reads unknown 6h ago

    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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 1b284a4cea171f8e.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/1b284a4cea171f8e/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/1b284a4cea171f8e/badge.svg)](https://brick.blue/agent/1b284a4cea171f8e?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
70%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
