# UECortex

Native Unreal Engine 5 plugin that runs a full [MCP (Model Context Protocol)](https://modelcontextprotocol.io) server inside the Unreal Editor. Control your project directly from Claude Code, VS Code, or any MCP client — no Python sidecar, no Node.js process, no external dependencies.

**139 tools** across 13 categories. Pure C++.

## Quick Start

### 1. Install

Copy the `UECortex` folder into your project's `Plugins/` directory and enable it in your `.uproject`:

```json

  "Enabled": true
}
```

Reopen the project. The server starts automatically on editor launch.

### 2. Connect

**Claude Code:**
```bash
claude mcp add uecortex --transport http http://localhost:7777/mcp
```

**VS Code** (`.vscode/mcp.json`):

{ "servers": { "uecortex": { "url": "http://localhost:7777/mcp" } } }
```
