About
Unity MCP Server is a Model Context Protocol server that connects AI assistants (Claude, Cursor, VS Code, Claude Code, etc.) directly to the Unity Editor, enabling LLM-driven game development workflows. Key capabilities include: - Asset management: Import, organize, and manipulate textures, models, audio, and other project assets - Scene control: Create and manage scenes, GameObjects, hierarchies, and transforms; includes multi-scene editing and scene templates - Script editing: Create, modify, and refactor C# scripts with API awareness - Build automation: Trigger player builds, switch target platforms (PC, Mac, mobile, console), configure player settings, and manage build profiles - Package management: Install, remove, search, and manage Unity packages and scoped registries via Package Manager - Graphics and rendering: Configure post-processing volumes, URP renderer features, light baking, and access real-time rendering stats - Camera control: Manage Camera components and Cinemachine virtual cameras with presets, blending, noise, and extensions - API documentation: Access Unity ScriptReference, Manual, and package documentation; inspect live C# APIs via reflection - Editor automation: Execute menu items, manage layouts, handle undo/redo, and perform batch operations Works with Unity Editor (compatible with Unity 6+) via a companion Unity package available on the Unity Asset Store.

Create your Unity apps with LLMs! MCP for Unity bridges AI assistants (Claude, Claude Code, Cursor, VS Code, etc.) with your Unity Editor via the Model Context Protocol. Give your LLM the tools to manage assets, control scenes, edit scripts, and automate tasks.
Recent Updates
manage_editor gains undo/redo actions. manage_scene gains multi-scene editing (additive load, close, set active, move GO between scenes), scene templates (3d_basic, 2d_basic, etc.), and scene validation with auto-repair. New manage_build tool: trigger player builds, switch platforms, configure player settings, manage build scenes and profiles (Unity 6+), run batch builds across multiple platforms, and async job tracking with polling. New MaxPollSeconds infrastructure for long-running tool operations.unity_reflect and unity_docs tools for API verification: inspect live C# APIs via reflection and fetch official Unity documentation (ScriptReference, Manual, package docs). New manage_packages tool: install, remove, search, and manage Unity packages and scoped registries.
