What it does

Epic Games' Claude Code plugin talks to the ModelContextProtocol server inside Unreal Editor, which exposes hundreds of tools across 30+ toolsets: actors, Blueprints, materials, Niagara VFX, Control Rig, Sequencer level sequences and cameras, UMG widgets, the Gameplay Ability System and automation tests. The unreal-mcp skill teaches the agent to discover toolsets on demand, and a SessionStart hook tells it when it is inside an Unreal project. For video, Sequencer and Niagara let an agent block out cinematics and game-trailer shots in engine. It is listed in Anthropic's official plugin marketplace; if that marketplace is missing, run /plugin marketplace add anthropics/claude-plugins-official first.

Use when

• drive the Unreal Editor from Claude Code
• build a level, Blueprint, material or Niagara effect by prompt
• block out a cinematic or game-trailer shot in Sequencer
• spawn and arrange actors around a PlayerStart
• recompile C++ with Live Coding after an edit

Not for

• Conceptual or docs questions about Unreal (the skill skips them)
• Unity, Godot or Roblox projects: use unity-mcp, godot-mcp or roblox-studio-mcp
• Shared or untrusted machines: localhost is not a trust boundary

Install

• Claude Code: /plugin install unreal-engine-skills-for-claude-code@claude-plugins-official
• Any agent, with the vargai CLI: vargai install unreal-engine-mcp
