NetBox MCP Server

A Model Context Protocol (MCP) server that connects to NetBox and exposes network infrastructure data for use with Claude and other MCP-compatible LLMs.

Overview

This server provides a bridge between NetBox and MCP-compatible LLMs like Claude, allowing you to:

• Query and analyze your network infrastructure data
• Check device configurations and connections
• Examine virtualization clusters and virtual machines
• Analyze VLANs, IP address allocations, and more
• Generate network topology information
• Detect NVMe storage in clusters

The server exposes:

• Tools: Functions that perform operations

Requirements

• Python 3.10 or higher
• NetBox instance with API access
• NetBox API token with read permissions
• httpx library for HTTP requests
• mcp Python SDK for Model Context Protocol

Installation

Using uv (recommended)

# Create a virtual environment
uv venv
source .venv/bin/activate  # On Windows: .venv\\Scripts\\activate

# Install required packages
uv add mcp httpx

Using pip

# Create a virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\\Scripts\\activate

# Install required packages
pip install mcp httpx

Usage

Running the Server Directly

python netbox_server.py --url https://your-netbox-instance.example.com --token your-api-token

You can also set environment variables instead of using command-line arguments:

export NETBOX_URL="https://your-netbox-instance.example.com"
export NETBOX_TOKEN="your-api-token"
python netbox_server.py

Integration with Claude Desktop

To integrate with Claude Desktop:

1. Install Claude Desktop from https://claude.ai/download
2. Open the Claude menu and select "Settings..."
3. Click on "Developer" in the left sidebar
4. Click on "Edit Config"
5. Add the NetBox server configuration to claude_desktop_config.json:

{
  "mcpServers": {
    "netbox": {
      "command": "python",
      "args": [
        "/path/to/netbox_server.py",
        "--url",
        "https://your-netbox-instance.example.com",
        "--token",
        "your-api-token"
      ]
    }
  }
}

6. Save the file and restart Claude Desktop

Available Features

Tools

The server provides these tools:

• get_all_clusters - Get list of all clusters with key information
• get_cluster_virtual_machines - Get all VMs in a specific cluster
• get_cluster_interfaces - Get all interfaces from all VMs in a cluster

Example Queries for Claude

Once the server is connected to Claude Desktop, you can ask questions like:

• "Show me a list of all clusters in our NetBox instance"
• "Show me all the virtual machines in our primary cluster"
