  • Pass
    Lists tools

    tools/list returned 3 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 95 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 95 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    35 of 39 parameters have a description (90%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Fail
    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass

Capabilities

Tools 3

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.

Discovered
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.

Discovered
liuyao_cast

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.
