Welcome to WoalzCraft
WoalzCraft is an AI agent that lives inside the Unreal Engine 5 editor. Describe what you want in plain language and it builds it: Blueprints, C++ classes, levels, materials, Niagara VFX, audio, animation, gameplay systems, and cinematics. It exposes 390+ automation tools spanning the whole UE5 stack, and it can play its own work, screenshot the result, read runtime state, and fix itself.
Two ways to drive it
- As an MCP server (recommended). Point Claude Code, Cursor, Cline, or any MCP host at WoalzCraft and drive all 390+ tools from the AI agent you already use. This is the path that builds, plays, screenshots, and self-heals most reliably, because it runs on a frontier model. See MCP integration.
- The built-in Studio assistant. A conversational panel right in the editor. Bring your own provider key (OpenAI, Anthropic Claude, or Google Gemini), point it at any OpenAI-compatible endpoint, or run it 100% free and local with Ollama, no key and no cloud. Output quality tracks the model you connect.
Under the hood, three pieces work together:
- A UE5 editor plugin (C++) that runs inside your project and drives every editor operation through the Unreal reflection system.
- The embedded MCP server so external AI hosts can call the same tools.
- WoalzCraft Brain (optional): a hosted knowledge service that retrieves relevant few-shot examples and patterns. It is off until you connect it, and nothing breaks when it is offline.

Design principles
Bring your own AI. WoalzCraft never ships with a mandatory, metered AI provider. Drive it from an MCP host (Claude Code / Cursor) on your existing subscription, paste a provider key (OpenAI, Anthropic, Gemini, OpenAI-compatible), or run a local Ollama model for free. Switch anytime.
Local-first where possible. A bundled node catalogue, templates, and fallback patterns ship in the plugin, so it works with no cloud connection at all. The Brain enriches when reachable and never blocks when it is not.
Privacy by default. A purchased copy is yours to keep. WoalzCraft never sees your provider keys or prompts; those go straight to the provider you choose. With local Ollama, nothing leaves your machine. The community Brain is opt-in, and auto-sharing your Blueprints is off by default.
Perceive, play, verify. The agent does not generate blind. It compiles what it builds, runs Play-In-Editor, captures the viewport, reads runtime values, and reports back, so the AI can see whether a change actually worked.
Current status
WoalzCraft is in early-access beta and ships as a one-time purchase on Epic's Fab Marketplace. It is a deep authoring and verification engine, not a one-click "make me a finished game" button. The exact build number and release notes live on the changelog page.
What's stable today:
- Full-stack authoring: Blueprints, C++ (classes, structs, enums, interfaces), UMG, materials, Niagara VFX, animation Blueprints, behavior trees + EQS, GAS, audio + MetaSound, landscape, PCG, Sequencer cinematics with render-to-movie, and multiplayer replication.
- Self-verification: Play-In-Editor, viewport screenshots, runtime reads, and an AI playtester.
- MCP server for Claude Code, Cursor, Cline, and Windsurf, on by default.
- Plain-English compile-error translation and self-healing.
- Optional WoalzCraft account (free) for the community Brain and a "Sign in with Woalz" device flow.
- Public knowledge-base browsing at /search, no account required.
Where it depends on you: original high-fidelity art, audio, and motion-capture clips still come from external tools (you import them); final creative direction and polish stay with you. Very complex, multi-constraint edits depend on the strength of the AI model you connect, a frontier model via Claude Code outperforms a small local model on hard tasks.
Expect sharp edges in beta. Report issues on our Discord or at support@woalz.com.
