Unreal Engine shipped an official MCP. Unreal MCP lets a language-model assistant edit the scene inside the Unreal editor The viewport is an empty gridded ground. A red-green-blue move widget stands in the middle. A black panel sits on the right. The window title says Load Unreal MCP, and a line at the bottom still says accept edits. This is the official hook Epic wrote into the Unreal 5.8 docs. Once connected, an MCP-compatible coding assistant can spawn Actors, set lights, make material instances, inspect Slate widgets, or run automation tests. It can also tell you what you currently have selected. For people building scenes and materials in Unreal, the assistant can edit the project in front of it, instead of writing somewhere else and pasting it back. xitter.cf/UnrealEngine/status/21… dev.epicgames.com/documentat… The docs still mark it experimental. A lot of features are missing, and the interface will change. It listens on this machine by default, with no login. Don't open it to the outside.
