Four kinds of tools
- In-engine agents work inside the editor with full project context: Unity's assistant, Bezi, Coplay and Aura for Unity and Unreal, Ziva for Godot, Roblox Assistant.
- Engine MCP servers let the coding agent you already use (Claude Code, Cursor, Codex) control the editor: Unity CLI MCP, Unreal MCP, the MCP server built into Roblox Studio, MCP for Unity, Godot MCP and MCP for Blender.
- AI characters: Inworld and Convai power NPCs that talk and react to the game world.
- Asset generation for game teams: Scenario, Layer and Ludo.ai, plus the 3D, image and sound APIs on APIs for agents.
Where to start
Already using a coding agent? Add your engine's MCP server first: it is free and keeps your own model subscription. Prefer a ready assistant inside the editor? Try the in-engine agents' free tiers. Need art, 3D or sound? Compare 3D model generation, image and audio APIs.
