Which integrations are available for this server?

Provides a searchable index of the Enfusion and Arma Reforger script API, utilizing data scraped from Doxygen documentation to assist in script and mod creation. Integrates with Arma Reforger Tools (distributed via Steam) to facilitate building and validating Enfusion engine addons through the Workbench CLI.

How do I use enfusion-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@enfusion-mcp Create a zombie survival game mode with waves of AI enemies" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

enfusion-mcp

MCP server for Arma Reforger / Enfusion engine modding. Create working mods from natural language — no modding experience required.

What It Does

Connect this server to any MCP-compatible client and describe what you want:

"Create a zombie survival game mode with waves of AI enemies"
"Add a custom faction with unique loadouts"
"Make a spawn system with weighted random positions"

12 MCP tools search 8,693 API classes, scaffold the addon, generate scripts/prefabs/configs, validate everything, and build it — all through conversation.

Installation

npx (no install)

npx -y enfusion-mcp

Global install

npm install -g enfusion-mcp

From source

git clone https://github.com/Articulated7/enfusion-mcp.git cd enfusion-mcp npm install npm run scrape # Build the API index from local Workbench docs npm run build

Setup

MCP Client Configuration

Add to your MCP client config:

{ "mcpServers": { "enfusion-mcp": { "command": "npx", "args": ["-y", "enfusion-mcp"], "env": { "ENFUSION_PROJECT_PATH": "C:\\path\\to\\your\\mod" } } } }

Local Build

If running from source, point your client at the compiled entry point:

{ "mcpServers": { "enfusion-mcp": { "command": "node", "args": ["C:\\path\\to\\enfusion-mcp\\dist\\index.js"], "env": { "ENFUSION_PROJECT_PATH": "C:\\path\\to\\your\\mod" } } } }
