# Does Unreal Engine have an MCP server?

- Endpoint: `Built into Unreal Editor 5.8 (experimental Unreal MCP plugin, local HTTP) — in-product`
- Category: [Gaming](https://mcpyet.com/category/gaming/)
- Verified against vendor docs: 2026-09-29
- GitHub data refreshed: 2026-09-29 (re-checked every 6 hours)

## The receipts

- **In-product:** Built into Unreal Editor 5.8 (experimental Unreal MCP plugin, local HTTP) — in-product — ships inside Unreal Engine's own product rather than as a standalone server. Documented at <https://dev.epicgames.com/documentation/unreal-engine/unreal-mcp-in-unreal-editor>.

## How to connect it

Ships inside the vendor's own app or CLI rather than as a standalone download.

### Claude Code

```sh
claude mcp add unrealengine -- npx -y <package-from-readme>
```

Swap in the exact package and flags from the repo README — most servers need an API key passed as an environment variable. Add `--scope user` to make it available in every project.

### Claude Desktop

Open **Settings → Developer → Edit Config** and add the server to `claude_desktop_config.json`, then restart Claude Desktop:

```json
{
  "mcpServers": {
    "unrealengine": {
      "command": "npx",
      "args": [
        "-y",
        "<package-from-readme>"
      ],
      "env": {
        "API_KEY": "…"
      }
    }
  }
}
```

### Cursor

Add to `.cursor/mcp.json` in your project, or `~/.cursor/mcp.json` for every project:

```json
{
  "mcpServers": {
    "unrealengine": {
      "command": "npx",
      "args": [
        "-y",
        "<package-from-readme>"
      ],
      "env": {
        "API_KEY": "…"
      }
    }
  }
}
```

### VS Code

Add to `.vscode/mcp.json`, then pick the server from Copilot's agent-mode tools menu:

```json
{
  "servers": {
    "unrealengine": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "<package-from-readme>"
      ]
    }
  }
}
```

### ChatGPT

ChatGPT connects to **remote servers only**, and this one runs on your machine. Either expose it through an MCP gateway that gives it a public URL, or use a client with native local support (Claude or Cursor).

## How we know

Epic documents Unreal MCP at dev.epicgames.com: an official Experimental plugin in Unreal Engine 5.8 that embeds an MCP server in the editor so agents can spawn actors, edit materials and lighting, and run automation tests.
