## 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 2026-08-03.

- **Endpoint Security**: 63/100
  - 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 not yet verified: we couldn't determine whether a plaintext access path exists.
  - 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**: 72/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1659 tokens (~165/item across 10 items; 5 tools + 5 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### `ask` (~540 tokens)

一文で聞けば、正しい窓口に繋ぐ

Check whether a construction or renovation quote in JAPAN is fairly priced, against 65,520 open catalogue items and Bitcoin-anchored verification records. Single entry point: pass one sentence.
USE WHEN: the user has a quote or a price for building/renovation work in Japan and wants to know if it is reasonable; or wants to check a HORIZON SHIELD receipt or a jidec: citation; or asks about overcharging tactics used by contractors; or is looking for a verified contractor.
DO NOT USE WHEN: the work is outside Japan; the question is not about construction or renovation; the user has already signed or paid and needs consumer-protection help; or there is an active emergency (gas smell, collapse, water not stopping). In those cases this tool does not answer - it returns the appropriate outside destination instead, and says so.
Every reply carries verify (a URL that checks the answer) and limits (what the answer does NOT prove). Routing is a deterministic keyword table, not an LLM, so the same input always routes the same way.
Examples: "is 800,000 yen high for exterior wall painting?" / "is jidec:entry:9 genuine?" / "how do I refuse a door-to-door sales pitch?"
日本の建設・リフォーム見積もりが適正かを確認する単一入口。日本語の一文で渡してよい。適正診断・台帳(JIDEC)の記録検証・過剰請求の手口・検証済み加盟店の4方向へ決定的に振り分ける。日本国外/建設以外/契約後の紛争/緊急時は**答えずに適切な外部の窓口を返す。**返り値には必ず verify(検証URL)と limits(証明していないこと)が入る。

Input parameters:

- `amount` (number): (任意)業者提示の金額(円)
- `ask` (string): やりたいことを一文で。例:「外壁塗装80万は高いですか」「jidec:entry:9 は本物ですか」
- `ref` (string): (任意)検証したい引用ID。jidec:entry:N / 64桁hex / エントリ番号
- `work` (string): (任意)工事名。分かっているなら渡すと推測を挟まない。

### `orchestrate` (~240 tokens)

集客→診断→発信 一括実行

1回の呼び出しで HORIZON SHIELD の集客→診断→注意喚起→発信を一気通貫で回す司令塔。work(と任意の quoted_price)を渡すと、内部で intake(KIRA適正診断)・scan_tactics(検証済み手口+一次ソース)・draft_broadcast(発信下書き+被リンク)を順に実行し、結果を1つに束ねて返す。価格は検証可能な一次データのみ。発信は下書きで自動投稿しない。 / One-call orchestrator returning audit + tactics + broadcast draft. Verifiable first-party prices only. Drafts only, no auto-posting.

Input parameters:

- `quoted_price` (number): (任意)業者提示の金額(円)。あればKIRA適正診断も実行する。
- `work` (string, required): 工事名やキーワード(日本語)。例: 外壁塗装, トイレ, シロアリ

### `intake_estimate` (~185 tokens)

見積もり適正診断(KIRA)

施主の建設・リフォーム見積もりを受け付け、HORIZON SHIELD KIRA(内部・中立)の適正価格診断へ橋渡しする集客窓口。工事名と業者提示額を渡すと、適正かどうかの判定と、無料の第三者チェック(EHN)への導線を返す。価格の断定はせず、確認すべき点を渡す。 / Intake desk: bridges a homeowner quote to the KIRA fair-price audit and returns the verdict plus a free third-party check (EHN) path.

Input parameters:

- `quoted_price` (number, required): 業者提示の金額(円)
- `work` (string, required): 工事名(日本語)。例: 外壁塗装 シリコン

### `scan_tactics` (~167 tokens)

過剰請求の手口スキャン

ある工事・キーワードに関する『過剰請求の手口』を、HORIZON SHIELD(大賀俊勝30年監修)の検証済みデータ(内部KIRA)から返し、一次ソース(国民生活センター/消費者庁/EHN実例ボード)の在処を添える。価格判定ではなく注意喚起。推測で新事例を断定しない。 / Returns verified overcharge tactics and points to primary sources. Awareness, not a price verdict.

Input parameters:

- `work` (string, required): 工事名やキーワード(日本語)。例: 外壁塗装, シロアリ, 火災保険

### `draft_broadcast` (~182 tokens)

注意喚起の発信下書き

ある工事の過剰請求への注意喚起を発信する下書き(note用長文・X用短文)を生成し、HORIZON SHIELDの該当解説ページ(実在URL)への被リンクを添える。価格はKIRA(検証可能SHA-256付き)の一次データのみ。推測の数字は入れない。下書きであり公開前に運営者が最終版にする(自動投稿しない)。 / Generates broadcast DRAFTS with backlinks. Verifiable first-party prices only. Draft; operator finalizes. No auto-posting.
