FAQ

Yes. MifBridge is an Unreal Engine editor plugin with an MCP server, so Claude Code or any other MCP client can work in the Unreal Editor through 717 typed endpoints. The plugin also serves a plain HTTP API on your own machine.

Unreal Engine 5.3 to 5.8. Each version was swept live on a stock editor for this release, and the Engine support page has the results for each one.

Yes. MifBlender, a free MIT-licensed Blender add-on, serves 364 typed operations, and the MCP server that comes with MifBridge turns them into tools for your AI assistant. Unreal does not have to be open. It is tested on Blender 3.6.23, 4.2.17 LTS, 4.4.0, 5.0.1, 5.2.1 LTS, and declares Blender 4.4 as its minimum.

The bridge reads the value back from the editor asset after a write. It does not echo the request and call that success.

Yes, within what cooking leaves behind. A cooked Blueprint has no graphs to read or edit, and the bridge says so instead of returning an empty list; a write that would crash on stripped data is refused with the reason. Cooked-content behavior is verified on UE 5.3.2, the one cooked project available for testing. The Cooked Projects page in the docs covers what works.

No. The read, scratch, and full mode gate is not a CVar, console command, or endpoint.

Any MCP client. The MifBridge panel sets up Claude Code with one button, the same setup script writes a checked entry for Cursor, Claude Desktop or Codex, and other clients connect with a standard .mcp.json entry.

The Unreal plugin and the typed Blender operations do not: the assistant chooses editor commands, and Unreal or Blender builds every asset from their parameters. One optional Blender path makes a 3D model from text or an image through a ComfyUI install you run yourself, and MifBridge ships no models for it. The page Using MifBridge Without Generative AI shows where the line is.

Not by default. In the default scratch mode, saves, Play In Editor, cooks and console commands are refused, and so are asset renames, because the engine saves a renamed asset. Deleting needs an explicit confirm, and a call that would change more than 25 things shows you the list and writes nothing until that list is committed. Only a person can raise the mode, in the editor.

It is a one-time payment, with Personal and Professional licenses, on the store page of this site or on Fab. The MifBlender add-on is free.
