Zyxel Server

A comprehensive Model Context Protocol (MCP) server for Zyxel switch CLI commands, enabling AI applications to interact with Zyxel switches for network configuration, monitoring, and management operations.

✅ PRODUCTION READY: Real Zyxel CLI Commands Integrated

This MCP server now contains authentic Zyxel CLI commands and response formats extracted from official Zyxel documentation (407-page CLI Reference Guide). All mock implementations have been replaced with real command syntax.

Features

• ✅ Real CLI Command Support: Authentic Zyxel switch CLI commands from official documentation
• ✅ Production-Ready Responses: Actual command output formats for GS1920/GS1900/XGS series
• ✅ Network Configuration: Interface configuration, VLAN management, and routing setup
• ✅ Real-time Monitoring: System status, port statistics, and network diagnostics
• ✅ Secure Operations: Authenticated command execution with proper error handling
• ✅ MCP Compliance: Full Model Context Protocol implementation with tools, resources, and prompts

As MCP Server

Configure your MCP client to use this server:

{
  "mcpServers": {
    "zyxel": {
      "command": "npx",
      "args": ["zyxel-mcp-server"]
    }
  }
}

Development Mode

npm run dev

Configuration

The server can be configured through environment variables:

• ZYXEL_DEFAULT_HOST - Default switch IP address
• ZYXEL_DEFAULT_USERNAME - Default username
• ZYXEL_DEFAULT_PASSWORD - Default password
• ZYXEL_TIMEOUT - Command timeout in milliseconds (default: 30000)
• ZYXEL_DEBUG - Enable debug logging (true/false)

Examples

Connecting to a Switch

// Use the zyxel_connect tool
{
  "host": "192.168.1.100",
  "username": "admin",
  "password": "admin123",
  "port": 22
}

Creating a VLAN

// Use the zyxel_create_vlan tool
{
  "vlanId": 100,
  "name": "Production_VLAN",
  "description": "Production network VLAN"
}
