Claude-Modeling-Labs MCP Server

A comprehensive, modular toolkit for interacting with Cisco Modeling Labs (CML) through the Model Context Protocol (MCP) interface. This server enables automated lab creation, topology management, device configuration, and network testing for educational and development purposes.

Features

Core Capabilities

• Lab Management: Create, start, stop, and delete CML labs
• Topology Building: Add routers, switches, and create network links
• Device Configuration: Apply and retrieve device configurations
• Console Access: Execute commands on network devices
• Network Discovery: Inspect lab topologies, nodes, and interfaces

Key Benefits

• Modular Architecture: Clean separation of concerns across handlers
• Educational Focus: Perfect for networking students and instructors
• Automation Ready: Designed for agentic AI tutoring systems
• Windows Compatible: Modular design resolves previous Windows compatibility issues

Installation

Prerequisites

• Python 3.8 or higher
• Access to a Cisco Modeling Labs server
• Valid CML credentials

Quick Start

1. Clone or download this repository
2. Install dependencies:

   pip install -r requirements.txt
   

3. Run the MCP server:

   python claude_modeling_labs_modular.py
   

Development Installation

pip install -e .[dev]

Usage

Initialize Connection

# First, initialize the client with your CML server details
initialize_client(
    base_url="https://your-cml-server.com",
    username="your-username", 
    password="your-password",
    verify_ssl=True  # Set to False for self-signed certificates
)

Basic Lab Operations

# Create a new lab
lab = create_lab("My Network Lab", "Learning OSPF routing")

# Create network devices  
router1 = create_router(lab["lab_id"], "R1", x=100, y=100)
router2 = create_router(lab["lab_id"], "R2", x=300, y=100) 
switch1 = create_switch(lab["lab_id"], "SW1", x=200, y=200)

# Connect devices
link_nodes(lab["lab_id"], router1["node_id"], router2["node_id"])
link_nodes(lab["lab_id"], router1["node_id"], switch1["node_id"])

# Start the lab
start_lab(lab["lab_id"])
wait_for_lab_nodes(lab["lab_id"], timeout=120)

Device Configuration

# Apply configuration to a router
ospf_config = """
hostname Router1
interface GigabitEthernet0/0
 ip address 10.1.1.1 255.255.255.0
 no shutdown
router ospf 1
 network 10.1.1.0 0.0.0.255 area 0
"""
configure_node(lab["lab_id"], router1["node_id"], ospf_config)

# Retrieve current configuration
current_config = get_node_config(lab["lab_id"], router1["node_id"])

Console Commands

# Execute commands on devices
send_console_command(lab["lab_id"], router1["node_id"], "show ip route")
check_interfaces(lab["lab_id"], router1["node_id"])

# Send multiple commands
commands = [
    "show version",
    "show ip interface brief", 
    "show running-config"
]
send_multiple_commands(lab["lab_id"], router1["node_id"], commands)

Architecture

The modular design separates functionality into focused handlers:

src/
├── client/           # CML API authentication and HTTP client
├── handlers/         # Modular tool handlers
│   ├── lab_management.py    # Lab CRUD operations
│   ├── topology.py          # Node and link management  
│   ├── configuration.py     # Device configuration
│   └── console.py           # Console session management
├── utils/            # Common utilities and helpers
└── server.py         # Main MCP server entry point

Key Design Principles

• Separation of Concerns: Each handler focuses on one aspect of CML management
• Clean Dependencies: Minimal coupling between modules
• Error Handling: Consistent error handling across all operations
• Windows Compatibility: Modular structure avoids file size limitations
