unreal-engine-skills-for-claude-code-plugin: Control Unreal Editor

What it does

This plugin gives Claude Code a skill for driving Unreal Editor through the editor’s Model Context Protocol server. The project exposes Unreal’s registered toolsets for tasks involving actors, Blueprints, materials, Niagara, Sequencer, widgets, and other editor areas. A session-start hook also tells Claude Code that the repository is an Unreal project and to prefer Unreal conventions. The source says the tool catalog is discovered on demand by default rather than loading every editor tool into the assistant at once.

How to use it

Install the plugin from Anthropic’s Claude Code marketplace, enable ModelContextProtocol and AllToolsets in Unreal Editor, and start the editor’s MCP server. Then ask Claude Code to perform an editor task, such as listing actors in the current level; the result is visible in the editor or its output log.

Common use cases

• Ask the agent to list actors in the open level and receive the current actor list.
• Use the exposed Blueprint or material tools to change an item in the running Unreal project, then inspect the edit in the editor.
• Ask Claude Code to invoke Unreal automation testing tools and review the test output.
