About UnrealClaude

UnrealClaude is an open-source plugin that integrates Claude Code CLI directly into the Unreal Engine 5.7 Editor, providing AI-powered coding assistance. It features a native editor chat panel with live streaming responses, an MCP server offering 20+ tools for actor manipulation, Blueprint editing, level management, materials, input, and more. A dynamic UE 5.7 context system loads accurate API documentation on demand. Additional capabilities include Blueprint and Animation Blueprint creation, level and asset management, async task queues, script execution via Live Coding, session persistence, and project-aware context gathering. It uses Claude Code authentication, eliminating separate API key management. Supported on Windows, Linux, and macOS, it requires building from source and a Claude Code subscription.
