🚀

INSTALLATION & QUICK START

Prerequisites

• Unreal Engine 5.7+

• Python 3.12+

• Git (only for GitHub installation)

• MCP Client (VS Code, Claude Desktop, Cursor, Windsurf)

1
Install VibeUE Plugin
Choose one of the following installation methods:

🌟 Option A: Install from FAB (Recommended)

✅ Easy installation - No manual setup required

✅ Automatic updates - Get the latest features

✅ Verified builds - Tested and stable releases

1. Open your Unreal Engine project

2. Go to Window > FAB (or Window > Marketplace in older versions)

3. Search for "VibeUE"

4. Click Install to Engine or Add to Project
⚙️ Option B: Clone from GitHub (Advanced)

For developers who want the latest development version or need to modify the source code.
```
cd /path/to/your/unreal/project/Plugins
git clone https://github.com/kevinpbuckley/VibeUE.git
cd VibeUE
buildplugin.bat
```
Example for Windows: cd C:\MyProject\Plugins

⚠️ Important: Run the buildplugin.bat file after cloning to properly configure the plugin.
2
Enable the Plugin in Unreal Engine
If you installed from FAB, the plugin may already be enabled. Skip this step if VibeUE is already active.

1. Open your Unreal Engine project

2. Go to Edit > Plugins

3. Find "VibeUE" in the Editor category

4. Check the box to enable it (if not already enabled)

5. Restart the editor when prompted

The plugin will build automatically when enabled.

Configure MCP Client

VS Code (Recommended)

1. Install the "Model Context Protocol" extension from VS Code marketplace

2. Create or update .vscode/mcp.json in your project root with one of the configurations below (choose the one matching your installation):

📁 Option A: Local Installation (GitHub Clone)

Use this if you cloned VibeUE into your project's Plugins folder:

{
  "servers": {
    "VibeUE-Local": {
      "type": "stdio",
      "command": "python",
      "args": [
        "-m",
        "vibe_ue_server"
      ],
      "env": {
        "PYTHONPATH": "${workspaceFolder}\\Plugins\\VibeUE\\Content\\Python"
      },
      "cwd": "${workspaceFolder}\\Plugins\\VibeUE\\Content\\Python"
    }
  },
  "inputs": []
}

🎮 Option B: Engine Installation (FAB Marketplace)

Use this if you installed VibeUE via FAB. Find your Engine plugin path by searching for vibe_ue_server.py:

{
  "servers": {
    "VibeUE-Engine": {
      "type": "stdio",
      "command": "python",
      "args": [
        "-m",
        "vibe_ue_server"
      ],
      "env": {
        "PYTHONPATH": "E:\\Program Files\\Epic Games\\UE_5.7\\Engine\\Plugins\\Marketplace\\[PLUGIN_ID]\\Content\\Python"
      },
      "cwd": "E:\\Program Files\\Epic Games\\UE_5.7\\Engine\\Plugins\\Marketplace\\[PLUGIN_ID]\\Content\\Python"
    }
  },
  "inputs": []
}

Replace [PLUGIN_ID] with your actual plugin folder name.

3. SAVE the file and click Run button inside JSON file to start the MCP Server.

💡 Choose only ONE configuration above - use Option A for local installs, Option B for FAB installs.

Other MCP Clients

Use this configuration for Claude Desktop, Cursor, Windsurf, Rider or other MCP Clients:

{
  "mcpServers": {
    "VibeUE": {
      "command": "uv",
      "args": [
        "--directory",
        "[YOUR_PROJECT_PATH]Plugins\\VibeUE\\Content\\Python",
        "run",
        "vibe_ue_server.py"
      ]
    }
  }
}

4
Test the Installation

1. Open Unreal Engine with your project

2. Open your MCP client (VS Code, Claude Desktop, etc.)

3. Ask your AI assistant: "Search for widgets in my project"

4. Success! If it returns widget information, VibeUE is working
