Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "public-data": {
      "command": "npx",
      "args": [
        "-y",
        "@appmonster/mcp-public-data"
      ],
      "env": {
        "DATA_GO_KR_KEY": "your-value",
        "JUSO_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add public-data --env DATA_GO_KR_KEY=your-value --env JUSO_KEY=your-value -- npx -y @appmonster/mcp-public-data

Fill in the empty values before running it.

Open in Cursor
