Unity-MCPMCP Server + Plugin for Unity Editor and Unity game. The Plugin allows to connect to MCP clients like Claude Desktop or others.

When to use MCP Prompt?

Provide domain knowledge - Share best practices and coding standards specific to your project Set coding conventions - Establish naming conventions, architecture patterns, and code style Give context about project structure - Explain how your project is organized and why Share workflow instructions - Provide step-by-step procedures for common tasks Inject specialized knowledge - Add information about specific Unity features, third-party assets, or custom systems Examples: "Always use PascalCase for public methods and camelCase for private fields" "This project uses a custom event system located in Scripts/Events/" "When creating UI elements, always add them to the Canvas in Scene/UI/MainCanvas" "Performance is critical - prefer object pooling for frequently instantiated objects" "This project follows SOLID principles - explain any architecture decisions"

What is MCP Prompt?

MCP Prompt allows you to inject pre-defined prompts into the conversation with the LLM. These are smart templates that can provide context, instructions, or knowledge to guide the AI's behavior. Prompts can be static text or dynamically generated based on your project's current state. Key characteristics: Contextual guidance that influences how the AI responds Role-based - can simulate different personas (User requests or Assistant knowledge) Dynamic content - can include real-time project data Reusable templates for common scenarios and workflows

What is MCP Resource?

MCP Resource provides read-only access to data within your Unity project. Unlike MCP Tools that perform actions, Resources allow the LLM to inspect and understand your project's current state, assets, and configuration. Think of them as "sensors" that give the AI context about your project. Key characteristics: Read-only access to project data and Unity objects Structured information presented in a format the LLM can understand Real-time data that reflects the current state of your project Contextual awareness helping the AI make informed decisions

When to use Tool?

Automate repetitive tasks - Create tools for common operations you do frequently Complex operations - Bundle multiple Unity API calls into a single, easy-to-use tool Project-specific workflows - Build tools that understand your project's specific structure and conventions Error-prone tasks - Create tools that include validation and error handling Custom game logic - Expose your game's systems to AI for dynamic content creation Examples: Creating and configuring GameObjects with specific components Batch processing assets (textures, materials, prefabs) Setting up lighting and post-processing effects Generating level geometry or placing objects procedurally Configuring physics settings or collision layers
