Korea Real Estate MCP

English | 한국어

Warning

Deprecation Notice — effective June 1, 2026

ChatGPT support will be removed. The required OAuth flow (Auth0 + PKCE + DCR) is too complex to maintain as a personal project and will be re-evaluated for a future release.

Caddy reverse proxy support will be removed. Cloudflare Tunnel is the recommended replacement and is already available in docker/docker-compose.yml via --profile cloudflare. See docs/setup-reverse-proxy.md for migration instructions.

Onbid (공매) support will be removed. Onbid's API has required repeated patches that are no longer sustainable to maintain as a personal project. All get_public_auction_* and get_onbid_* tools will be deleted.

Supported Tools

• Apartment trade / rent (get_apartment_trades, get_apartment_rent)
• Officetel trade / rent (get_officetel_trades, get_officetel_rent)
• Villa / multi-family housing trade / rent (get_villa_trades, get_villa_rent)
• Single-house / multi-household trade / rent (get_single_house_trades, get_single_house_rent)
• Commercial building trades (get_commercial_trade)
• Apartment subscription notices / results (get_apt_subscription_info, get_apt_subscription_results)
• Onbid public auction bid results (get_public_auction_items, get_public_auction_item_detail) / 🗑️ Removed June 1, 2026

Quick Start: Claude Desktop (stdio)

The fastest way to get started — the server runs as a child process of Claude Desktop.

1. Clone this repository locally.

   git clone <repository_url>
   cd real-estate-mcp

2. Open the Claude Desktop config file.

   # macOS
   open "$HOME/Library/Application Support/Claude/claude_desktop_config.json"

   # Windows
   notepad %APPDATA%\Claude\claude_desktop_config.json

3. Add the entry below under mcpServers.

   {
     "mcpServers": {
       "real-estate": {
         "command": "uv",
         "args": [
           "run",
           "--directory", "/path/to/real-estate-mcp",
           "python", "src/real_estate/mcp_server/server.py"
         ],
         "env": {
           "DATA_GO_KR_API_KEY": "your_api_key_here"
         }
       }
     }
   }

4. Restart Claude Desktop. Setup is complete when you can see the real-estate server in the tool list.

5. For better responses, create a Project in Claude Desktop and paste resources/custom-instructions-ko.md into the Project Instructions tab.
