UAIP 1.0.0 is now available on Fab.
Unreal AI Integration Platform (UAIP) exposes the UE Editor and Runtime as a structured API for AI agents to drive via the Model Context Protocol (MCP). Tools like Claude Code, Codex CLI, Cursor, Windsurf, and GitHub Copilot can connect and issue semantic commands — no coordinate clicks, no brittle UI scripting.
Trailer
Fab listing: Unreal AI Integration Platform (UAIP) — AI Agent Harness for UE | Fab
What it does
- 540+ native semantic commands spanning Editor, Runtime, and Observation domains
- 190+ bridges to UE 5.8’s official Toolset — combined ~730+ commands from one API
- Self-verifying mutation loops — AI captures screenshots and reads them back to confirm its own work
- Graph editor support — Blueprint / Material / Niagara / AnimBlueprint / ControlRig / Sequencer / PCG / MetaSound / BehaviorTree / StateTree / Dataflow / EQS / CommonConversation
- Beyond graphs — level editing, asset CRUD, PIE control, UI automation, state dumps (editor / world / Slate tree), Automation Test execution
- Scenario execution — ordered command batches with per-step timeout / retry / abort policy and value splicing between steps
- Per-session Capability + process-wide SafetyPolicy — let an AI loose on a real project without watching every step
- Multi-transport — MCP, HTTP, WebSocket, CLI all hit the same dispatcher
Compatibility
- Unreal Engine 5.7 and 5.8 (Toolset only covers 5.8)
- Windows (Win64)
Try before you buy
A free demo build covering ~60 commands (observation, PIE control, UI automation, scenario execution) is available on GitHub Releases. Same architecture as the full version, just with a watermark on captures.
