AI Game Developer is the second large community Unity bridge. Where MCP for Unity focuses on the MCP server, this project also generates skills from your project, so the agent arrives knowing your project's structure. Marking any C# method with one attribute turns it into a tool the agent can call.
The CLI handles the whole setup. If you would rather avoid the CLI, install the plugin through OpenUPM or the .unitypackage.
Requirements
- Unity
- Node.js for the CLI
- An ai-game.dev sign-in for the CLI flow
