Prerequisites

Quick Start: Claude Desktop (stdio)

  1. Clone this repository
git clone https://github.com/coding-realtor/building-register-mcp.git
cd building-register-mcp
  1. 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
  1. Add the entry below under mcpServers
{
  "mcpServers": {
    "building-register": {
      "command": "uv",
      "args": [
        "run",
        "--directory", "/path/to/building-register-mcp",
        "data-go-mcp-building-register"
      ],
      "env": {
        "BUILDING_REGISTER_API_KEY": "your_api_key_here"
      }
    }
  }
}

Replace /path/to/building-register-mcp with the actual path where you cloned the repository.

  1. Restart Claude Desktop

Setup is complete when you can see the building-register server in the tool list.

Usage Example

Tell me about the building at 서울 종로구 청운동 89-3

Claude will automatically:

  1. Look up the region code via search_bjdong_code
  2. Call smart_building_lookup to fetch building details
  3. Present the results in a readable table
