The bridge between AI and Unreal Engine.
CLAUDIUS (Claude's Unreal Direct Interface & Unified Scripting) is a powerful automation framework that lets external tools control the Unreal Editor through simple JSON commands. Whether you're using AI coding assistants like Claude Code, building Python automation scripts, or integrating UE5 into your CI/CD pipeline — CLAUDIUS makes it possible.
Built for AI Assistants
CLAUDIUS includes a CLAUDE.md documentation file that AI assistants automatically read. This means Claude Code instantly understands how to spawn actors, create Blueprints, render cinematics, and control your entire project through natural language.
120+ Commands Across 17 Categories
From spawning actors and creating Blueprints to rendering sequences and controlling AI behavior trees — CLAUDIUS covers the full spectrum of editor automation:
Level: Spawn, modify, query, and delete actors
Blueprint: Create Blueprints, add variables, functions, and components
Asset: Import, search, rename, and manage assets
Sequencer: Create sequences, add tracks, set keyframes, render cinematics
AI: Create behavior trees, blackboards, control navigation
Build: Compile Blueprints, trigger live coding, package projects
Viewport: Control camera, take screenshots, change view modes
Console: Execute commands, manage CVars, control Play-In-Editor
And 9 more categories including Animation, Recording, Physics, and Landscape
Two Integration Methods
Choose what works for your workflow. The HTTP REST API provides real-time control with 10-50ms response times. File-based communication offers simple JSON file polling, perfect for Claude Code and basic automation scripts.
Runtime Control
CLAUDIUS doesn't stop at editor automation. Control actors, AI blackboards, and game state during Play-In-Editor for testing and debugging without stopping the simulation.
