Editor-only, by design

CrimsonEditorUtilities is an Editor-type plugin — it loads in the editor and ships nothing in cooked builds. There's no runtime API and no Blueprint/C++ split in this course; everything here is about your workflow, not your game.

Its two jobs

  • Crimson MCP toolsets — behind a master switch, it exposes AI-callable toolsets (source files, plugins, assets & tags) to agents like Claude Code and Cursor, using UE 5.8's Model Context Protocol support.
  • Toolbar helpers — a Save Game deleter and a Common Maps opener, both a click away on the editor toolbar.
Where the switch lives
The MCP toolbar button and the master switch (Crimson MCP settings) live in CrimsonCommon's editor module — this plugin contributes the three toolsets that appear once it's on.
