About Coplay MCP server
Automating repetitive Unity development tasks through natural language commands is the primary function of this plugin. Game developers use it to create and modify game elements, generate scripts, and manage project assets directly within the Unity editor. The tool functions as an AI copilot that understands the specific structure of your scenes and scripts to provide context-aware assistance.
To use this plugin, you must have Unity 2022.3 or newer installed. You add it to your project via the Package Manager using a specific git URL. Once the plugin is imported, you can access the interface through the window menu or a keyboard shortcut. Users are required to log in or create an account through a browser window to enable functionality. The system supports various AI models including GPT-4.1, Gemini 2.5 Pro, Claude 4-Sonnet, and Grok 3. It also features a pipeline system to record and replay sequences of actions for faster iteration.
What you can do with it
- 1Automate repetitive editor actionsA developer can record a sequence of manual steps and replay them to save time during iteration.
- 2Generate and fix game codeYou can ask the AI to write new scripts or help resolve errors within your existing codebase.
