Install the plugin
Install Blueprint Stack from FAB into Unreal Engine 5.4+. The MCP server starts automatically when the editor opens.
Unreal Engine AI Assistant
An AI assistant that lives inside Unreal Engine
Blueprint Stack turns Unreal Engine 5.4+ into a workspace your AI assistant can actually use. Build Blueprints, generate materials, author Niagara VFX, and edit data — through chat.
Bring Claude Code, OpenAI Codex, or any MCP-compatible assistant into the editor. The plugin exposes 48 first-party tools so the AI does not just talk about Unreal — it edits Unreal.
Live editor session

complete / The AI splits movement, health, and inventory into components, rewires references, and verifies the original behavior still works.
Workflow
How the assistant works
Three steps from install to AI-driven gameplay creation.
Connect your assistant
Point Claude Code, Codex CLI, or your custom MCP host at the editor. The full tool catalog is discovered automatically.
Build through conversation
Describe what you want. The assistant calls editor tools to make it happen, while you watch the changes land in real time.
Things the AI assistant can do
A sampling of real workflows people run every day with Blueprint Stack.
Prompt / 01
"Refactor my player Blueprint into a clean component-based setup."
Result
The AI splits movement, health, and inventory into components, rewires references, and verifies the original behavior still works.
Prompt / 02
"Build a stylized post-process material with chromatic aberration."
Result
It authors the post-process material, adds a parameterized aberration node graph, and assigns it to a post-process volume.
Prompt / 03
"Generate a flame Niagara system and trigger it from the torch Blueprint."
Result
It builds the Niagara system, adds emitters and modules, then wires the torch Blueprint to spawn it on activation.
Prompt / 04
"Bulk-rename and reorganize the Items folder by category."

The assistant scans the folder, proposes a category structure, and moves and renames assets after you confirm the plan.
FAQ
Frequently asked questions
How is this different from a chat window with copy-paste?+
The AI assistant calls real editor tools. It actually creates Blueprints, edits materials, and saves assets — no copy-paste, no manual translation step.
Which AI assistants does it work with?+
Any MCP client. Claude Code and OpenAI Codex CLI are the most common. Custom agents work too — bring your own model and account.
Will it touch files I do not want it to?+
You stay in control. The plugin runs in the editor, so you see every change as it lands and can undo at any point.
Does it support image and 3D asset generation?+
Yes. Built-in tools generate images via DALL-E and 3D models via Meshy AI, then import them into Unreal as ready-to-use assets.
Will I get future updates?+
Yes. One-time purchase, lifetime updates. New tools, agent integrations, and editor coverage roll out continuously.
