The Unity MCP Server enables AI-assisted development of Unity projects through programmatic interaction, offering comprehensive control over:
- Project Management: Set up, validate, and manage Unity projects
- Asset Creation & Management: Create and manage scripts, scenes, materials, shaders, and editor scripts
- Material Handling: Create, update, clone materials, change shaders, and modify properties
- Code Management: Create, update, analyze scripts, handle namespaces, and manage compilation
- UI Toolkit Development: Create and manage UXML layouts, USS styles, and complete UI components
- Editor Extensions: Build custom editor windows, property drawers, and scriptable object editors
- Build Automation: Build for multiple platforms (Windows, macOS, Linux, iOS, Android, WebGL)
- Diagnostics: Analyze logs, validate assets, run tests, and monitor compilation
- Batch Operations: Execute efficient bulk operations on multiple assets
- AI Integration: Analyze requirements, generate project structures, and implement game systems like player controllers, cameras, UI frameworks, and audio managers
Supports building Unity projects for Android as one of the available build targets.
Supports building Unity projects for iOS as one of the available build targets.
Supports building Unity projects for Linux (StandaloneLinux64) as one of the available build targets.
Supports building Unity projects for macOS (StandaloneOSX) as one of the available build targets.
Utilizes Node.js as the runtime environment for the MCP server, with Node.js 18.x or higher required.
Implements the MCP server using TypeScript for type-safe development and better code organization.
Enables direct interaction with Unity projects, providing tools for script creation, asset management, shader creation, custom editor extensions, ProBuilder integration, package management, and project building for multiple platforms.
Supports building Unity projects for WebGL as one of the available build targets.
Unity 6 MCP Bridge v3.0.0
Direct Unity API integration for AI-powered game development
Unity 6 MCP Bridge provides seamless integration between AI assistants (like Claude) and Unity Editor through direct Unity API calls. This is a complete rewrite of the previous MCP server, designed specifically for Unity 6000+ with breaking changes from v1.x/v2.x.
Features
Unity 6 Integration
- Direct Unity API calls via Named Pipes/Domain Sockets
- Real-time synchronization with Unity Editor
- Native AssetDatabase operations (no more meta file issues!)
- Roslyn-powered code analysis and IntelliSense
- Unity 6 template system for code generation
Script Operations
- script_create - Generate scripts from Unity 6 templates
- script_read - Read script content from Unity project
- script_delete - Safe deletion with reference checking
- script_rename - Rename with class name updates
Folder Management
- folder_create - Create with automatic parent directories
- folder_delete - Safe deletion with asset cleanup
- folder_rename - Rename with reference updates
- folder_list - List with Unity metadata
Installation
Prerequisites
- Unity 6000.0 or later (Required)
- Node.js 18+
- Claude Desktop or compatible MCP client
1. Install MCP Bridge
2. Install Unity Package
- Download
MCPBridge.csfrom this repository - Place it in
Assets/Editor/MCP/MCPBridge.csin your Unity project - Unity will automatically compile and start the bridge
3. Configure Claude Desktop
Add to your Claude Desktop configuration:
Quick Start
1. Start Unity 6
Open your Unity 6 project. The MCP Bridge will automatically start and listen for connections.
2. Connect with Claude
Open Claude Desktop and start using Unity commands:
3. Verify Connection

Advanced Features
Real-time Code Analysis
The bridge provides real-time Roslyn-powered analysis:
- Syntax error detection
- Reference finding
- Usage analysis
- IntelliSense data
Template System

Configuration
Environment Variables
UNITY_MCP_LOG_LEVEL- Set logging level (debug, info, warn, error)UNITY_MCP_TIMEOUT- Request timeout in milliseconds (default: 30000)
Unity Settings
The bridge automatically detects Unity installation and project settings. No manual configuration required.
Troubleshooting
Common Issues
"Unity Bridge disconnected"
- Ensure Unity 6000+ is running
- Verify MCPBridge.cs is in
Assets/Editor/MCP/ - Check Unity Console for errors
"Method not implemented"
- Verify Unity version (6000.0+ required)
- Check if Newtonsoft.Json package is installed
- Update Unity to latest 6.x version
Permission Errors
- On macOS/Linux, ensure socket file permissions
- Run Unity with appropriate permissions
- Check firewall settings
