MCP Demo Lab MCP Server

Provides an MCP server that exposes 35 network tools to AI assistants for device management and topology insights.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "e-conners-lab-mcp-demo-lab": {
      "command": "python",
      "args": [
        "network_mcp_server.py"
      ],
      "env": {
        "R1_HOST": "10.0.0.1",
        "R2_HOST": "10.0.0.2",
        "DEMO_MODE": "true",
        "NETBOX_URL": "http://localhost:8000",
        "NETBOX_TOKEN": "YOUR_TOKEN",
        "DEVICE_PASSWORD": "admin",
        "DEVICE_USERNAME": "admin"
      }
    }
  }
}

You deploy a Python-based MCP server that exposes 35 network tools to AI assistants, enabling direct, multi-vendor control over your routers, switches, and firewalls through natural language commands and automated checks. This server guides you from installation to running in demo mode, and provides practical workflows to explore device health, topology, routing, and configuration management with your preferred MCP client.

How to use

Connect your MCP client (such as Claude Desktop or ChatGPT) to the MCP server and start issuing natural language commands. For example you can ask the AI to check the health of all devices, discover topology, view routing tables, or push configurations. Your AI assistant will translate these requests into the available tools and perform the actions against your device inventory.

How to install

Prerequisites: Python 3.11+, a supported operating environment, and network accessibility to your devices. You will also need a Python virtual environment to isolate dependencies.

# 1) Clone the project
git clone https://github.com/E-Conners-Lab/MCP-DEMO-LAB.git
cd network-mcp

# 2) Create and activate a virtual environment
python -m venv .venv
source .venv/bin/activate

# 3) Install dependencies
pip install -r requirements.txt

Optional quick-start steps to run a demo server without real devices.

# Demo mode returns realistic mock data — no devices needed
DEMO_MODE=true python network_mcp_server.py

Configuration notes

Configure device access by creating an environment configuration file and listing device endpoints and credentials. You can enable mock/demo mode to explore features without live devices, or connect to real devices by providing hostnames or IPs and authentication details in the environment.

Connecting a client to the MCP server

Once the server is running, connect your MCP client by pointing it at the local server process. In demo mode you will be able to exercise 35 tools without requiring live devices.

Try with a real lab (5 minutes)
