Public construction cost data for Japan and the U.S., each row with its source URL and licence.
HORIZON SHIELD Construction Cost Data: JCCDB (Japan) and USCCDB (United States) is an MCP server entry in ChatHome Skills, sourced from Official MCP Registry and scored 78/100. As a Model Context Protocol server, it exposes tools that MCP-compatible LLM clients such as Claude, Cursor, and Copilot can call directly, extending an agent's reach beyond its built-in capabilities. ChatHome Skills discovered this entry through its daily ingest of official registries and GitHub discovery queries, and re-verifies repository facts, freshness signals, and install metadata on every run. The quality score weighs official-registry presence, a working install command, license clarity, GitHub star trajectory, and repository freshness — the full formula is on the Sources page. The install command above is ready to copy. Review the last-pushed date and repository status before adding HORIZON SHIELD Construction Cost Data: JCCDB (Japan) and USCCDB (United States) to a production agent workflow; the snapshot facts below are point-in-time values from the most recent ingest.
