MifBridge

MifBridge lets Claude, or any AI app that supports the Model Context Protocol (MCP), work inside Unreal Engine and Blender. It has two parts: a plugin for the Unreal Editor (Unreal Engine 5.3 to 5.8, Windows) and MifBlender, a free MIT-licensed add-on for Blender. You talk to the AI in its own window and watch it build Blueprints, levels, materials, animation and more in the editor. After every change, MifBridge reads the editor's real state back and tells the AI what actually happened, and when a value is refused it lists the values that would work. A person sets the permission level (read, scratch or full) in the editor, and the AI cannot raise it. Version 1.0.0 has 458 Unreal commands, 189 Blender operations and 669 MCP tools, tested on six Unreal versions and five Blender versions.
