概览

AI 生成的概览

远程 MCP 服务器，为助手提供日本（JCCDB）与美国（USCCDB）的公开建筑成本数据，每行均附来源网址与许可。

功能
通过只读查询工具提供公开建筑成本数据集。日本工具涵盖条目检索、带来源引用的观测记录、按都道府县与工种划分的国土交通省公共工程设计劳务单价、同一条目的地区对比、工程单价、成本指数序列以及覆盖范围查询。美国工具涵盖各层级公开价格、Davis-Bacon 现行工资、人口普查建筑许可、国防部地区成本系数、从到岸进口成本到承包商的价格链、批发零售毛利以及公共合同折扣。每行数据均带来源网址与许可，计算值会被标记，查询失败返回 fetch_failed 而非空结果。
适用场景
当助手需要日本或美国建筑成本的可引用参考数据时使用，例如查询公共工程单价、劳务费率、现行工资、许可、指数，或进口与毛利链条。这些是参考数据而非装修报价，输出应作为进一步分析的输入。
运行要求
远程 Streamable HTTP 端点 API 密钥、身份验证、环境变量或请求头，也无需本地安装包；需要能访问该端点的网络。
安装前请注意
该服务器为只读，不要求任何凭据，因此不会传输机密信息。其计算值标记为 computed:true，应与带来源引用的数据行区分。公共工程单价、统计与链条估算属于参考数据，不是装修报价，不应作为有约束力的价格呈现。README 说明这些数据工具是从另一台服务器迁移而来，旧服务器可能仍会应答。

安装

在 SourceWeft 中

  1. 打开 控制台中的 HORIZON SHIELD Construction Cost Data: JCCDB (Japan) and USCCDB (United States)，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

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.
