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.
