VibeUE brings AI directly into Unreal Engine with an In-Editor Chat Client and Model Context Protocol (MCP) integration. Plan, inspect, create, and modify Blueprints, assets, materials, animation, landscapes, audio, UI, AI behavior, project settings, and more through natural language.

🔑 A free VibeUE API key is required for the MCP server and AI Chat to work. Get yours at vibeue.com/login — then paste it into the VibeUE settings gear icon inside Unreal Editor. See the AI Clients setup guide for IDE configuration.

• External IDE Integration - Connect VS Code, Claude Code, Cursor, and AntiGravity via MCP

🏗️ Architecture Overview

VibeUE uses a Python-first architecture that gives AI assistants access to:

1. MCP Tools (10 tools)

Lightweight MCP tools for AI interaction with Unreal:

Note: The read_logs MCP tool provides access to Unreal Engine's log files for debugging, error analysis, and workflow understanding.

Note: The manage_asset MCP tool is the preferred path for asset search, save, move, duplicate, and delete workflows. It avoids ad hoc Python asset handling and preserves references when renaming or moving content.

Note: The terrain_data and deep_research tools work together for real-world terrain workflows: geocode a place name → generate a heightmap → import into a landscape → fetch water features.
