ReforgerForge MCP
Allows GitHub Copilot to assist with Arma Reforger modding by providing tools for API lookup, script creation, asset browsing, and Workbench automation.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@ReforgerForge MCPsearch API for ExplosiveDamage and code a script"
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.
ReforgerForge MCP
The universal AI modding toolkit for Arma Reforger.
Describe what you want to build — your AI agent handles API research, code generation, project scaffolding, Workbench control, and in-editor testing. Works with any MCP-compatible agent: Cursor, Google Antigravity, Claude Desktop, Claude Code, Kiro, Windsurf, VS Code Copilot, Continue.dev, and more.
Forked from steffenbk/enfusion-mcp-BK with permission. ReforgerForge adds universal agent support, simplified setup, and ongoing maintenance as an independent project.
Features
50 MCP tools — API search, wiki, asset browsing, code generation, Workbench live control
8,693 indexed API classes — full Enfusion/Arma Reforger class hierarchy
250+ wiki guides — searchable tutorials and documentation
Agent-agnostic — one server, install script for every major AI IDE
Zero modding experience required — natural language → built addon

Quick Start
git clone https://github.com/goatboynz/reforger-forge-mcp.git
cd reforger-forge-mcp
npm install
npm run buildOr on Windows:
.\scripts\setup.ps1Then install into your agent(s):
# Install into ALL supported agents at once
.\scripts\install-agents.ps1 -All
# Or pick one
.\scripts\install-agents.ps1 -Agent antigravity
.\scripts\install-agents.ps1 -Agent cursorRestart your agent and verify reforger-forge shows 50 tools.
Configure paths
Copy and edit the config file:
cp reforger-forge.config.example.json reforger-forge.config.jsonKey | Description |
| Arma Reforger Tools (Steam) install |
| Arma Reforger game install |
| Where your mods are saved |
Re-run .\scripts\install-agents.ps1 after changing paths so all agents get updated env vars.
Agent Setup
ReforgerForge uses stdio MCP (local Node.js process). Every agent below runs the same server — only the config file location differs.

Workspace config: .cursor/mcp.json (included). Global: run install script or merge configs/cursor-global.json.

Claude Desktop
Merge configs/claude-desktop.json or run install script.

# macOS / Linux

Uses servers key (not mcpServers). Run install script — it writes both user-level and workspace .vscode/mcp.json.
Command palette: MCP: List Servers → verify reforger-forge is running.
Windsurf (Cascade)
Global config only at ~/.codeium/windsurf/mcp_config.json. Run install script, then refresh MCP list in Cascade panel.
Continue.dev
Run install script. MCP servers live inside ~/.continue/config.json under mcpServers.
Any other MCP client
Use the stdio template at configs/agents/stdio-template.json. Replace REPLACE_WITH_ABSOLUTE_PATH with your clone path.
