## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-18.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 62/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 381 tokens (~190/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 89/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 63% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-17 (score 69, +1)

No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-13 (score 67, +1)

## MCP tools (2)

### `heart_fit` (~136 tokens)

Check whether a question fits YOWAYOW Mind-Key

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.

Input parameters:

- `locale` (string)
- `question` (string, required): The user's original question before six-position evidence mapping.

Output parameters:

- `ai_used` (boolean)
- `method_version` (string)
- `status` (string)

### `heart_cast` (~245 tokens)

YOWAYOW Mind-Key structural 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.

Input parameters:

- `decision_context` (object, required)
- `environment` (object, required): Upper trigram: the dominant external constraint or interaction environment.
- `locale` (string)
- `purpose` (string, required): Why the agent needs the cast. This MCP does not support fortune-telling or traditional liuyao.
- `question` (string, required): A concrete structural or action question. Not a fortune, luck, hidden-fact, or pure prophecy question.
- `subject` (object, required): Lower trigram: the controllable, acting, or focal side.

Output parameters:

- `ai_used` (boolean)
- `fallback_used` (boolean)
- `method_version` (string)
- `mode` (string)
- `status` (string)
