ClaudeUnreal lets Claude — or any MCP-capable agent — control Unreal Engine 5 through natural language. Pick a starting point below.

01

Install & set up

Fab → enable → Python + uv. The plugin auto-writes .mcp.json.

02

Understand the surface

17 always-loaded MCP tools (hot-path + discovery) + a cu CLI for the long tail.

03

Use a different agent

Not on Claude Code? Wire it into Cursor, Cline, Windsurf, Antigravity, & more.

Any MCP client →

// Works with any agent

Not Claude-specific. Any MCP-capable agent drives the same bridge.

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.

Note

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.
