概览

AI 生成的概览

远程 MCP 服务器，让助手对照公开成本数据库判断日本建筑或装修报价是否合理。

可以做什么: 审核业主报价：传入工程类型和可选的日元金额，得到合理价格判定与应向承包商确认的问题
查询某类工程已核实的超额收费手法，并附一手来源指引
一次调用串联受理、手法扫描与宣传草稿，返回合并结果
生成带解释页面链接的宣传草稿（长文与短文）
读取数据集、工程类别、价格区间与免费复核平台等参考资源与模板
适用场景: 当用户询问日本建筑或装修报价是否合理、想了解某类工程常见的超额收费套路，或需要一篇关于价格问题的提醒草稿时适用。仅面向日本与日元，且为只读。
运行要求: 远程 streamable HTTP 端点，无需 API 密钥。README 建议通过 npx 的 mcp-remote 桥接连接，因此本机需要 Node.js。数据仅覆盖日本与日元。

安装前请注意

README

HORIZON SHIELD — Construction Estimate Auditor for Japan (KIRA)

A Model Context Protocol (MCP) server that lets an AI agent check whether a Japanese construction or renovation quote is fair — auditing it against an open 95,403-item cost database, flagging known overcharge tactics, and returning a verifiable, tamper-evident result. Neutral third party. No referral fees. No auto-posting.

WebMCP Intake (KIRA) is the public intake desk of HORIZON SHIELD. A homeowner commissioning construction work cannot reliably tell whether a quote is honest — a textbook credence-good problem. This server makes a neutral, third-party fair-price audit callable as a tool, so an agent can check a number instead of trusting it.

Protocol: Model Context Protocol (MCP), streamable HTTP
Endpoint: https://web.horizonshield.dev/mcp
Access: read-only, no API key required
Data region: Japan (JPY) — built on the open JCCDB dataset (95,403 line items) + 61 curated work categories
Supervision: 30 years of construction field experience (Toshikatsu Oga, ORCID 0009-0000-9180-903X)
Operator: THE HORIZONS INC — independent, takes no referral fees or kickbacks from contractors

What it does

Give it a work type (e.g. 外壁塗装 / exterior wall painting) and, optionally, the quoted price in JPY. It returns a fair-price verdict, flags known overcharge tactics with primary-source citations, and can draft public awareness content — all from verifiable first-party data, never guessed numbers. It never pressures, never auto-posts, and never gives a bare "too high / too low"; it hands you what to ask the contractor.

Tools

Tool	What it does
`orchestrate`	Start here. One call runs intake + tactic-scan + broadcast-draft together and returns a single bundle. The fastest way to see the whole server.
`intake_estimate`	Bridges a homeowner's quote (work + price in JPY) to the KIRA fair-price audit; returns a verdict plus a path to a free third-party check (EHN).
`scan_tactics`	Returns verified overcharge tactics for a given work type, with pointers to primary sources (Japan Consumer Affairs Agency, NCAC, the EHN case board). Awareness, not a price verdict.
`draft_broadcast`	Generates awareness drafts (long-form for note, short for X) with real backlinks. Verifiable first-party prices only; draft only — the operator finalizes. No auto-posting.

Try it (example prompts)

Once connected, ask your agent:

外壁塗装の見積もりが120万円。適正か診断して → runs intake_estimate
Is a ¥1,200,000 exterior-wall-painting quote fair for a Japanese house? → intake_estimate
シロアリ駆除でよくある過剰請求の手口を教えて → scan_tactics
Run the full HORIZON SHIELD check on 屋根塗装, quoted ¥900,000 → orchestrate

Resources & prompts

Resources: about-horizon-shield, jccdb-dataset-info (95,403 items, license + citation), souba-categories (61 work categories), souba-sources (fair-price sources + regional multipliers), ehn-info (free anonymous estimate-review board). Resource templates: souba://category/{query} (category search), souba://price/{work} (fair price range: min / avg / max). Prompts: diagnose_my_estimate, how_to_read_an_estimate.

Connecting

This is a remote MCP server — point any MCP client at the endpoint:

json

{  "mcpServers": {    "horizon-shield-intake": {      "command": "npx",      "args": ["-y", "mcp-remote", "https://web.horizonshield.dev/mcp"]    }  }}

{  "mcpServers": {    "horizon-shield-intake": {      "command": "npx",      "args": ["-y", "mcp-remote", "https://web.horizonshield.dev/mcp"]    }  }}

Why trust it

Neutral third party. Takes no referral fees or send-off rewards from contractors.
Verifiable. Fair prices are returned as tamper-evident records with a SHA-256 hash, under a Pre-Transaction Knowledge Anchoring model (a third party records the fair price before the contractor's quote).
Open data. Built on the public JCCDB dataset (95,403 line items) plus 61 curated categories with maintained price ranges and red flags.
No pressure, no auto-posting. It returns what to ask, points to primary sources, and never publishes on its own.

Version numbering, and a correction

The version in server.json, which is what the MCP registry publishes, and the version this server reports in serverInfo were two different numbers for most of this server's life.

2026-08-03   serverInfo 0.5.02026-08-09   serverInfo 0.5.0, server.json 0.4.12026-08-09   server.json published to the registry as 1.0.22026-09-04   serverInfo 0.6.0, server.json and the registry still 1.0.2

2026-08-03   serverInfo 0.5.02026-08-09   serverInfo 0.5.0, server.json 0.4.12026-08-09   server.json published to the registry as 1.0.22026-09-04   serverInfo 0.6.0, server.json and the registry still 1.0.2

Measured on 2026-09-04 against the live endpoint: serverInfo.version came back 0.6.0 while the registry said 1.0.2. The other four servers in this repository keep the two numbers equal, so this one was the exception rather than the rule, and the exception was written down nowhere.

Registry versions cannot go backwards, so 0.6.0 could not be published to correct it. Both numbers were moved forward to 1.0.3 instead, and the period during which they disagreed is recorded here rather than removed. Found by a full sweep of every server in this repository, prompted by the same class of drift on hs-verify-gate (PR #17) and hs-hearing (PR #18), where the code was ahead of the registry rather than behind it.

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 the open JCCDB (526,128 records: line items and observations) 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。

USE WHEN: the caller wants all three steps (audit, tactics, broadcast draft) for one named work item in a single call and will act on the combined result. DO NOT USE WHEN: only one step is needed. Call intake_estimate for a verdict on a specific quote, scan_tactics for the documented overcharge tactics, or draft_broadcast for publishable text. If the request is still a free-form question with no work item, call ask first. This tool never posts anything.
