Quick Start

1. Configure devices

cp devices.json.example devices.json
cp .env.example .env

Edit devices.json with your device inventory. Passwords use ${ENV_VAR} references resolved from .env:

{
  "devices": [
    {
      "id": "cisco-sw-core",
      "name": "Cisco Core Switch",
      "type": "cisco",
      "transport": ["ssh"],
      "host": "192.168.1.1",
      "port": 22,
      "username": "admin",
      "password": "${CISCO_PASSWORD}",
      "tags": ["core", "network"]
    }
  ]
}

2. Docker (Recommended)

docker compose up -d

Server runs at http://localhost:3300 (MCP endpoint: /mcp, health: /health)

3. Standalone

npm install
npm run build
npm run start:sse   # Streamable HTTP mode (port 3000)
npm start           # stdio mode (for Claude Desktop)

4. Connect to Claude Code

.mcp.json is pre-configured:

{
  "mcpServers": {
    "iot": {
      "url": "http://localhost:3300/mcp"
    }
  }
}

VPN Support

Container รองรับ 5 VPN protocols เพื่อเข้าถึงอุปกรณ์ที่อยู่หลัง VPN:

VPN	Config Location	Auto-connect
OpenVPN	vpn/openvpn/*.ovpn	ทุก .ovpn file
WireGuard	vpn/wireguard/*.conf	ทุก .conf file
Tailscale	TS_AUTHKEY in .env	เมื่อมี authkey
Cloudflare Tunnel	CF_TUNNEL_TOKEN in .env	เมื่อมี token
ZeroTier	ZT_NETWORKS in .env	เมื่อมี network IDs

Setup OpenVPN

วาง .ovpn config files ไว้ใน vpn/openvpn/:

cp your-vpn-config.ovpn vpn/openvpn/

Setup WireGuard

วาง WireGuard config ไว้ใน vpn/wireguard/:

cp wg0.conf vpn/wireguard/

Setup Tailscale

สร้าง auth key จาก https://login.tailscale.com/admin/settings/keys แล้วใส่ใน .env:

TS_AUTHKEY=tskey-auth-xxxxxxxxxxxxx

Setup ZeroTier

สร้าง network ที่ my.zerotier.com แล้วใส่ network ID ใน .env (หลาย network คั่นด้วย comma):

ZT_NETWORKS=af78bf9436abcdef

อย่าลืม authorize member ใน ZeroTier Central หลัง container join แล้ว

Setup Cloudflare Tunnel

สร้าง Tunnel จาก Cloudflare Zero Trust Dashboard -> Networks -> Tunnels แล้วคัดลอก token ใส่ .env:

CF_TUNNEL_TOKEN=eyJhIjoixxxxxxx...

กำหนด Private Network routes ใน Cloudflare Dashboard เพื่อให้ tunnel route traffic ไปยัง subnet ของอุปกรณ์

Device VPN Annotation

ระบุ VPN ที่อุปกรณ์ใช้ใน devices.json ด้วย field vpn (optional, ช่วยให้ Claude รู้ว่าอุปกรณ์อยู่หลัง VPN ไหน):

{
  "id": "cisco-remote",
  "name": "Cisco Remote Switch",
  "type": "cisco",
  "host": "10.8.0.100",
  "vpn": "openvpn",
  "tags": ["remote"]
}

Check VPN Status

ใช้ tool vpn_status เพื่อดูสถานะ VPN interfaces ทั้งหมด
