NetBox MCP Server

This is a simple read-only Model Context Protocol server for NetBox. It enables you to interact with your data in NetBox directly via LLMs that support MCP.

Tools

Tool	Description
get_objects	Retrieves NetBox core objects based on their type and filters
get_object_by_id	Gets detailed information about a specific NetBox object by its ID
get_changelogs	Retrieves change history records (audit trail) based on filters

Note: the set of supported object types is explicitly defined and limited to the core NetBox objects for now, and won't work with object types from plugins.

Usage

1. Create a read-only API token in NetBox with sufficient permissions for the tool to access the data you want to make available via MCP.

2. Install dependencies:

# Using UV (recommended)
uv sync

# Or using pip
pip install -e .

3. Verify the server can run: NETBOX_URL=https://netbox.example.com/ NETBOX_TOKEN=<your-api-token> uv run server.py

4. Add the MCP server configuration to your LLM client. For example, in Claude Desktop (Mac):

{
  "mcpServers": {
        "netbox": {
            "command": "uv",
            "args": [
                "--directory",
                "/path/to/netbox-mcp-server",
                "run",
                "server.py"
            ],
            "env": {
                "NETBOX_URL": "https://netbox.example.com/",
                "NETBOX_TOKEN": "<your-api-token>"
            }
        }
}

On Windows, use full, escaped path to your instance, such as C:\\Users\\myuser\\.local\\bin\\uv and C:\\Users\\myuser\\netbox-mcp-server. For detailed troubleshooting, consult the MCP quickstart.

4. Use the tools in your LLM client. For example:

> Get all devices in the 'Equinix DC14' site
...
> Tell me about my IPAM utilization
...
> What Cisco devices are in my network?
...
> Who made changes to the NYC site in the last week?
...
> Show me all configuration changes to the core router in the last month
