概覽

AI 產生的概覽

遠端 MCP 伺服器，讓助理取得日本（JCCDB）與美國（USCCDB）的公開建築成本資料，每列都附來源網址與授權。

功能
以唯讀查詢工具提供公開建築成本資料集。日本工具涵蓋項目檢索、附來源引用的觀測紀錄、依都道府縣與工種劃分的國土交通省公共工程設計勞務單價、同一項目的地區比較、工程單價、成本指數序列，以及涵蓋範圍查詢。美國工具涵蓋各層級公開價格、Davis-Bacon 現行工資、人口普查建築許可、國防部地區成本係數、從到岸進口成本到承包商的价格鏈、批發零售毛利，以及公共合約折扣。每列資料都帶來源網址與授權，計算值會被標記，查詢失敗會回傳 fetch_failed 而非空結果。
適用情境
當助理需要日本或美國建築成本的可引用參考數據時使用，例如查詢公共工程單價、勞務費率、現行工資、許可、指數，或進口與毛利鏈。這些是參考資料而非裝修報價，輸出應作為進一步分析的輸入。
執行需求
遠端 Streamable HTTP 端點 API 金鑰、身分驗證、環境變數或標頭，也不需要在本機安裝套件；需要能連線至該端點的網路。
安裝前請注意
此伺服器為唯讀，不要求任何憑證，因此不會傳送機密資訊。其計算值標記為 computed:true，應與附來源引用的資料列區分。公共工程單價、統計與鏈式估算屬於參考資料，不是裝修報價，不應作為有約束力的價格呈現。README 說明這些資料工具是從另一台伺服器遷移過來，舊伺服器可能仍會回應。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 HORIZON SHIELD Construction Cost Data: JCCDB (Japan) and USCCDB (United States)，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

其他 MCP 客戶端

把它新增到你客戶端的 mcpServers 設定中。

HORIZON SHIELD Construction Cost Data (JCCDB + USCCDB)

An MCP server (Streamable HTTP, stateless, no key) for public construction cost data:

Endpoint: https://ccdb.horizonshield.dev/mcp

ToolWhat it returns
search_jccdb_itemsJCCDB line items by name, with evidence URLs
get_jccdb_observationsWhere and when an item appears in public documents, with its price or the reason it is not public
get_jccdb_labor_rateMLIT public-works design labor rates by prefecture and trade
compare_jccdb_regionsLatest value per region for the same item, spec and unit
get_jccdb_work_unit_pricePublic-works unit prices for work items, with composition rows
get_jccdb_index_seriesConstruction cost index series with year-over-year change
get_jccdb_coverageWhat exists and what does not, before answering
get_us_construction_pricesU.S. public data across layers (wages, bids, equipment, indexes, permits, cost limits)
get_us_prevailing_wageDavis-Bacon base and fringe by state, county and trade
get_us_permitsCensus building permits and city permit valuations
get_us_area_factorDoD Area Cost Factors and USACE state adjustments
get_us_price_chainA material's price from landed import cost to wholesale, retail and contractor
get_us_import_landed_costLanded import cost by HS code and partner country
get_us_trade_marginsWholesale and retail gross margins and the BEA margin structure
get_us_contract_discountsPublic contract discounts off list price

Every row carries its source URL and licence. Values this service computes are marked computed:true. A lookup that could not be made comes back as fetch_failed:true, never as zero rows. Public-works unit prices, statistics and chain estimates are reference data, not renovation quotes.

To check whether a Japanese renovation quote is fair, use the HORIZON SHIELD server: https://mcp.horizonshield.dev/mcp. The two servers were one until 2026-10-02; the data tools moved here so each server does one job. The moved tools still answer on the old server for now, with a pointer here.

The tool definitions are generated from what the old server served (build/build_worker.py, build/data_tools.json), so names, descriptions and schemas did not change in the move. Test, offline: node test/ccdb.test.mjs.
