What is ClaudeUnreal?

ClaudeUnreal is an MCP server that bridges Claude Code and Unreal Engine 5.7+. 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: 13 typed MCP tools for the hot path (spawn / move / inspect / screenshot), plus a cu CLI for ~362 long-tail commands across Blueprint, UMG, Niagara, sequencer, and the rest. See the Architecture for the full picture, the CLI overview for cu, or the Reference for every command.
