What is archhub-mcp?

Archhub-mcp is an MCP server that wraps South Korea's Ministry of Land building registry APIs into eleven tools accessible through AI assistants. The underlying data comes from the government's Building Hub platform and covers building ledger records, construction permit histories, and housing permit details for every registered building in the country. The eleven tools cover a range of use cases. One tool takes an address keyword and returns the administrative district codes needed by the others. From those codes, you can retrieve a single building's comprehensive profile (legal use zone, main use, structure, floor area ratio, parking count, approval date, and seismic rating), a floor-by-floor breakdown of each level's use and area, or the assessed price history for residential units going back up to seventeen years. Separate tools return district-wide statistics (total buildings, use type breakdown, construction era distribution, and aging analysis), a filtered list of older buildings sorted by years since approval, a log of demolished structures with asbestos hazard flags by building component, and a view of permits issued but not yet approved sorted by most recent. All responses cite the official data source and use machine-parseable prefixes (NOT_FOUND, EXTERNAL_API_ERROR) when data is absent or an API call fails, rather than generating a plausible-sounding but incorrect answer. A remote server is running publicly. Users only need to register the provided URL in their AI client to start using all eleven tools without any API key setup or local installation. Claude.ai web users can add it as a custom connector, Claude Code users can add it with a single command, and other MCP clients can point to the URL in their configuration file. Local installation via the Python package is also documented for those who want to self-host. The full README is longer than what was shown.
