# Unreal Engine — AI Game Developer

Install the Unreal-MCP plugin into your C++ Unreal Engine project and drive the editor with AI. Supports Unreal Engine 5.5+ (tested on 5.7) and ships 90 MCP tools, including Blueprint and C++ authoring with a compile feedback loop.

_Last updated: 2026-06-17_

Requirements: Unreal Engine 5.5+ · tested on 5.7 · C++ project.

## Install — CLI (recommended)

```bash
npm install -g unreal-mcp-cli
unreal-mcp-cli install-plugin ./YourProject
unreal-mcp-cli login ./YourProject
unreal-mcp-cli open ./YourProject
```

## Install — Fab / Epic Marketplace (coming soon)

Installing Unreal-MCP from Fab via the Epic Games Launcher (precompiled, zero build) is not yet live. Until it lands, use the CLI option, which works today against any UE 5.5+ C++ project.

### Cloud (default)

Connect through ai-game.dev using the device-code OAuth flow — no tokens to copy by hand. From the AI Game Developer window choose Cloud, click Authorize, and approve the device code in your browser. Works across firewalls and gives you usage analytics. This is the default and what we recommend for most users.

### Custom (self-hosted)

Prefer to run everything locally? Point the plugin at your own gamedev-mcp-server instance instead of the hosted endpoint. Your AI client then talks straight to your machine. Client-by-client config snippets live on the MCP endpoint page (/mcp-endpoint-info).

## Example prompt

```text
Create a new Actor blueprint with a static mesh cube and place three of them in the level.
```
