Install Blueprint Stack
Install from FAB into UE 5.4+. The plugin starts an MCP server on port 9315 the moment the editor opens.
Claude Code for Unreal Engine
Run Claude Code inside the Unreal Editor
Blueprint Stack connects Claude Code directly to Unreal Engine 5.4+ through a built-in MCP server, so Claude can read your project, edit Blueprints, and generate assets without leaving the editor.
No copy-pasting between a terminal and the Unreal Editor. Claude calls 48 native editor tools to wire Blueprint graphs, build materials, spawn Niagara systems, edit data tables, and more — all from natural-language prompts.

Workflow
How Claude Code drives Unreal
Three steps from install to AI-driven Blueprint creation with the Claude Code CLI.
Point Claude Code at it
Add the MCP server to your Claude Code config. Claude now sees the Unreal project alongside the rest of your codebase.
Build in the chat
Ask Claude to wire a Blueprint, generate a material, or create a Niagara system. Tools run live against the editor.
Real prompts, real Blueprint output
A few of the things people use Claude Code with Blueprint Stack to do.
Prompt / 01
"Make a third-person character with double jump and dash on shift."
Result
Claude creates a Character Blueprint, configures the movement component, and wires input actions for jump and dash with cooldowns.
Prompt / 02
"Build a fire material with emissive flicker driven by Time."
Result
Claude opens the Material editor, adds noise + Time-driven panner nodes, and connects them to Emissive with a tunable intensity parameter.
Prompt / 03
"Generate a Niagara muzzle flash and trigger it from the weapon Blueprint."
Result
Claude builds a Niagara system, adds the spawn module, then edits the weapon Blueprint to spawn it on Fire.
Prompt / 04
"Create a data table for enemy stats and a struct to back it."
Result
Claude defines the struct, creates the data table asset, seeds rows for melee, ranged, and boss enemies, and wires a lookup helper.
FAQ
Frequently asked questions
Does this run the Claude Code CLI directly?+
Yes. Blueprint Stack exposes Unreal Engine as an MCP server. Point the Claude Code CLI at it and Claude can call editor tools as part of any conversation.
Which Unreal Engine versions are supported?+
Unreal Engine 5.4 and newer. The plugin ships through FAB and installs into the editor like any other plugin.
Do I need a Claude API key?+
You use your own Claude Code subscription or API key. Blueprint Stack is the bridge — it does not bill or proxy LLM tokens.
Can Claude edit existing Blueprints, or only create new ones?+
Both. Tools cover reading, modifying, and creating Blueprints, materials, Niagara systems, levels, data tables, and more.
Does this work with Codex or other agents?+
Yes. The MCP server is agent-agnostic. Codex CLI, custom agents, and any MCP-compatible client can drive the editor too.
