UE-MCP
A Model Context Protocol server that gives an AI assistant read and write access to the Unreal Engine editor, covering blueprints, materials, levels, animation and more through natural-language commands.
UE-MCP bridges an AI assistant to the Unreal Engine editor through a TypeScript MCP server that talks over WebSocket JSON-RPC to a C++ plugin running inside the editor, plus direct filesystem access to configuration files, C++ headers and the asset listing that works even while the editor is closed. Together, the server's own actions and Epic's native AI Toolset Registry on UE 5.8 and later cover well over a thousand actions across categories such as blueprints, materials, levels, animation, VFX, landscape, audio, UI, physics, navigation, networking and the build pipeline.
Setup is a single command that detects the project, lets the user choose which tool categories to enable, deploys and enables the required engine plugins, and configures a supported MCP client such as Claude Code, Claude Desktop, Cursor or Codex. A YAML flow engine supports multi-step workflows, and an npm plugin system lets the tool surface be extended further.
