eveng-mcp-server 0.1.0

MCP server providing Claude/LLM agents with programmatic access to EVE-NG network labs

EVE-NG MCP Server

An MCP (Model Context Protocol) server that gives Claude and other LLM agents programmatic access to EVE-NG network labs.

Create, configure, and manage virtual network topologies through natural language — no manual clicking in the EVE-NG web UI required.

Features

• Lab management — Create, list, get details, and delete labs
• Node operations — Add nodes from any installed template, start/stop individually or all at once
• Configuration push — Push startup configs to nodes before boot
• Network connectivity — Create networks and connect node interfaces
• Image discovery — List all available QEMU/Docker images on the server

Requirements

• Python >= 3.10
• An EVE-NG server (Community or Professional) with API access
• An MCP-compatible client (Claude Desktop, Claude Code, etc.)

Installation

# From source
git clone https://github.com/axiom-works-ai/eveng-mcp-server.git
cd eveng-mcp-server
pip install -e .

# With dev dependencies (for testing)
pip install -e ".[dev]"

Configuration

The server reads connection details from environment variables:

Variable	Default	Description
EVENG_HOST	http://192.168.122.10	EVE-NG API base URL
EVENG_USERNAME	admin	API username
EVENG_PASSWORD	eve	API password

Usage

Claude Desktop

Add to your Claude Desktop MCP configuration (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "eveng": {
      "command": "eveng-mcp-server",
      "env": {
        "EVENG_HOST": "http://192.168.122.10",
        "EVENG_USERNAME": "admin",
        "EVENG_PASSWORD": "eve"
      }
    }
  }
}

Claude Code

Add to your Claude Code settings (.claude/settings.json):

{
  "mcpServers": {
    "eveng": {
      "command": "eveng-mcp-server",
      "env": {
        "EVENG_HOST": "http://192.168.122.10",
        "EVENG_USERNAME": "admin",
        "EVENG_PASSWORD": "eve"
      }
    }
  }
}

Direct (stdio)

export EVENG_HOST=http://192.168.122.10
export EVENG_USERNAME=admin
export EVENG_PASSWORD=eve
eveng-mcp-server

Or run as a Python module:

python -m eveng_mcp_server

Available Tools

Lab Management

Tool	Description
list_labs	List all labs on the server
get_lab	Get lab details with nodes, networks, and topology
create_lab	Create a new lab
delete_lab	Delete a lab

Node Operations

Tool	Description
add_node	Add a node to a lab (specify template, RAM, CPU, interfaces)
start_node	Start a single node
stop_node	Stop a single node
start_all	Start all nodes in a lab
stop_all	Stop all nodes in a lab
get_node_status	Get node status and details

Configuration

Tool	Description
push_config	Push startup configuration to a node
get_node_config	Get a node's current startup configuration

Network Connectivity

Tool	Description
connect_nodes	Connect two node interfaces via a shared network

Discovery

Tool	Description
list_images	List all installed QEMU/Docker images

Example Conversation

You: Create a lab called "OSPF Demo" with two Arista vEOS switches connected together, then push basic OSPF configs to both.

The agent will:

1. Call create_lab to create "OSPF Demo"
2. Call list_images to find the vEOS template
3. Call add_node twice to add two vEOS switches
4. Call connect_nodes to link their interfaces
5. Call push_config on each node with OSPF configuration
6. Call start_all to boot the lab

Development

# Install with dev dependencies
pip install -e ".[dev]"

# Run tests
pytest

# Run linter
ruff check src/ tests/

EVE-NG API Notes

• The EVE-NG API uses session cookies (not bearer tokens) — the client authenticates once and reuses the session.
• Lab paths use URL-encoded filesystem paths (e.g., /api/labs/My%20Lab.unl).
• Node status codes: 0 = stopped, 1 = building, 2 = running.
• Startup configs should be pushed while the node is stopped.
