What it does

Epic Games' own MCP server for Unreal Engine, built into the editor as the experimental Unreal MCP plugin. The server runs inside the Unreal Editor process and listens on the local machine at 127.0.0.1:8000/mcp by default, over Streamable HTTP or server-sent events; stdio is not supported, and there is no authentication layer, so Epic advises against exposing it beyond the machine. Its tools come from toolsets in the editor's Toolset Registry, covering actors, Blueprints, widgets, materials, MetaSounds, PCG, Niagara, Sequencer, profiling and automation tests. With tool search on, agents see a few meta-tools and look up the rest. The editor can generate client configuration for Claude Code, Codex, Cursor, Gemini and VS Code.

Capabilities

  • Spawn and edit actors in the open level
  • Build and edit Blueprints and Widget Blueprints
  • Author materials, Niagara systems, PCG graphs and Sequencer content
