HORIZON SHIELD YAKUMO (verified contractor directory) is a remote MCP server that gives an AI agent 6 tools, among them check_named_contractor, find_contractor, get_contractor_profile. It answers at https://hearing.horizonshield.dev/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
Neutral, verification-gated MCP directory of Japan construction contractors (KIRA-audited).
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
check_named_contractor | 施主が名前を挙げた業者について答える。Yakumoの加盟店ならその測定結果を返す。加盟していない場合、その会社の良し悪しは一切判定せず、『Yakumoは測っていない』という事実だけを返し、施主が自分で確かめられる公的な照会先(国土交通省の建設業者検索・国民生活センター・住まいるダイヤル)と、同条件の検証済み加盟店を返す。掲載が無いことはその会社への評価ではない。金額は返さない。紹介料なし。Japan only。 Inputs: company, area, work |
find_contractor | 施主の相談文(自由記述)から Yakumo の検証済み加盟店を探す司令塔。need(例:『愛知県で外壁塗装できる信頼できる業者』)を渡すと地域と工種を推定し、検証を通過した店を返す。該当が無ければ相場(souba)や無料の第三者チェック(EHN)への導線を返す。金額は返さない(スコア・ティアのみ)。紹介料なし・verified-first・Japan only。 Inputs: need |
get_contractor_profile | Yakumo の加盟店1件の検証済みプロフィールを返す。member_no(例 No.001)で指定。会社名・地域・対応工種・適正度スコア・誠実度ティア・検証状態・プロフィールURLを返す。金額は含まない。検証が済んでいない店は verification:'pending' を返す(スコアは出さない=fail-closed)。 Inputs: member_no |
how_verification_works | Yakumo の掲載審査(KIRA適正診断)がどう機能するかを返す。適正価格の検証・過剰請求の赤旗検出・適正度スコアと誠実度ティア・再計算できる署名レシート(SHA-256)・掲載後の継続監視・fail-closed(通らない店は施主向けに一切出さない)・中立(紹介料なし)。施主が『検証済み』の意味を理解するための説明。 |
list_verified_stores | Yakumo モールで検証を通過した加盟店(工務店・リフォーム店)を一覧する。適正価格の検証と過剰請求チェック(KIRA)を通過した店だけが返る。area(地名)や work(工種)で絞り込める。返り値は member_no / 会社名 / 地域 / 対応工種 / 適正度スコア / 誠実度ティア / プロフィールURL。金額は含まない(スコアとティアのみ)。検証手続き中の店は verification:'pending' として区別される。Japan only. Inputs: area, work |
mall_overview | Yakumo モール全体の要約を返す。検証済み加盟店の数・対応工種カテゴリ・地域・検証の仕組みの要点・主要リンク(モール/加盟/相場/実例ボード)。AIが Yakumo というモール/MCP を一言で説明するための入口。金額は含まない。 |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://hearing.horizonshield.dev/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
