   cp .env.example .env

   Edit .env:

   ROUTER_HOST=192.168.1.1
   ROUTER_USER=root
   ROUTER_PASSWORD=your_password
   # Or use SSH_PRIVATE_KEY

2. Build:

   npm run build

Usage with MCP Client (e.g. Claude Desktop)

Add the following to your MCP client configuration (e.g., claude_desktop_config.json):

{
  "mcpServers": {
    "openwrt": {
      "command": "node",
      "args": ["/path/to/openwrt-mcp-server/dist/index.js"]
    }
  }
}

Make sure to replace /path/to/openwrt-mcp-server with the actual absolute path to this directory.
