Claude Code

UnrealClaude is a Claude Code plugin that brings AI-powered coding assistance into Unreal Engine 5.7's editor with native UE documentation context. It integrates the Claude Code CLI directly into the editor via a docked chat panel and runs an MCP server exposing 20+ tools for actor manipulation, Blueprint editing, level management, materials, and more. Developers can query UE5.7 APIs, generate C++ or Blueprint code, and execute scripts—all with the AI pre-loaded with accurate engine documentation. The plugin supports Windows, Linux, and macOS, persists conversation history across sessions, and requires a Claude Pro/Max subscription.
