Introduction

1 · Install & Enable

Install from Fab, enable in Edit → Plugins.

2 · Set up MCP

Install Python + uv locally. The plugin auto-writes .mcp.json on first editor start.

3 · Start building

Open a project, run ping from Claude Code to confirm the link, then describe what you want.

What is ClaudeUnreal?

ClaudeUnreal is an MCP server that bridges Claude Code and Unreal Engine 5.7 and 5.8. Claude controls the editor through a three-layer architecture (Python MCP → TCP bridge → C++ plugin) so natural-language intent becomes real engine actions — spawning actors, authoring Blueprints, editing materials, packaging builds.

The plugin exposes Unreal through a hybrid surface: typed MCP tools for the hot path (spawn / move / inspect / screenshot), plus a cu CLI covering a large long-tail of commands across Blueprint, UMG, Niagara, sequencer, and the rest. See Architecture & tools for how the hybrid surface and cu work.

Not on Claude Code? Nothing here is Claude-specific underneath — any MCP-capable agent (Cursor, Cline, Windsurf, Antigravity, …) can drive the editor over the same bridge. See Use with any MCP client. On UE 5.8 you can also mount ClaudeUnreal’s tools onto Unreal’s own built-in MCP server.
