Ludus FastMCP

A Model Context Protocol (MCP) server for automating Ludus cyber range environments through AI assistants written in Python.

Overview

Ludus FastMCP enables AI-powered management of Ludus cyber ranges through natural language commands. The server exposes 190+ tools across 20 modules for range lifecycle management, scenario deployment, template creation, Ansible role management, and security monitoring integration.

Supports both Ludus v1 and v2 with automatic version detection. All existing v1 tools work unchanged, and v2 adds blueprints, groups, VM console, diagnostics, enhanced range management, and more.

Key Capabilities

Category	Description
Range Management	Create, configure, deploy, and manage virtual lab environments
Blueprints	Save, share, and apply reusable range configurations (v2)
Groups	Organize users and ranges with group-based access control (v2)
Scenario Deployment	Pre-built scenarios for AD, red/blue/purple team, and malware analysis
Template Builder	Custom OS templates, skeleton configurations, and YAML generation
Role Management	Ansible Galaxy integration, custom roles, and subscription roles
SIEM Integration	Wazuh, Splunk, Elastic Stack, and Security Onion support
AI Configuration	Natural language to YAML configuration conversion
Diagnostics	System health, license info, and migration tools (v2)

Supported Platforms

Works with any MCP-compatible client including Claude Desktop, VS Code (Cline), OpenWebUI, and AnythingLLM.

Quick Start

Requirements

• Python 3.11+
• Access to a Ludus server instance (v1 or v2)
• Ludus API key or JWT token (for v2 Pro/SSO users)

Installation

# Using pipx (recommended)
pipx install git+https://github.com/tjnull/Ludus-FastMCP

# From source
git clone https://github.com/tjnull/Ludus-FastMCP
cd Ludus-FastMCP
pip install -e .

Setup

Run the interactive setup wizard:

ludus-fastmcp --setup

The wizard configures API credentials, tests connectivity, and generates MCP client configuration files.

For manual configuration options, see the Configuration Guide.

Usage

MCP Server (ludus-fastmcp)

ludus-fastmcp --setup          # Interactive setup wizard
ludus-fastmcp --list-tools     # List all 190+ available tools
ludus-fastmcp --version        # Display version information
ludus-fastmcp                  # Start MCP server
ludus-fastmcp --daemon         # Run as background service

Client CLI (ludus-ai)

ludus-ai setup-llm                    # Configure local LLM (Ollama)
ludus-ai install anythingllm          # Install AnythingLLM interface
ludus-ai tool list-tools              # List available tools
ludus-ai tool call-tool <name>        # Execute tools directly

Example Interactions

Once connected to an MCP client, interact with your Ludus environment:

Show my current range status
Deploy an Active Directory lab with Wazuh monitoring
Create a snapshot named "pre-attack" for all VMs
Build a lab with 2 domain controllers and 5 workstations
Create a blueprint from my current range and share it with the red-team group
Show system diagnostics and storage usage
List all groups and their members

Examples of using Ludus-FastMCP with grok code through Opencode.
