Common questions about connecting and running GB Studio.
What is GB Studio and why would I use this MCP server with it?
GB Studio is a visual game creation tool for Game Boy games. This MCP server lets Claude programmatically create and modify GB Studio projects—scenes, actors, and assets—so you can design levels and manage game structure through conversation instead of the UI.
Do I need a Claude API key to use this server?
The CLAUDE_API_KEY environment variable is optional and used only by specific /claude-key endpoints. Basic scene, actor, and asset operations work without it, but check the server documentation for which features require authentication.
How do I install and run the gbstudio-claude-mcp server?
Run `npx gbstudio-claude-mcp@1.0.4` to install and start the server. It communicates via stdio, so configure your Claude client (or MCP host) to spawn this process and pipe commands to it.
Can this server validate my GB Studio project for errors?
Yes—the server includes validation tools to check your project structure. You can ask Claude to validate your project and report issues, though specific validation rules depend on the GB Studio version and schema the server supports.
What happens if I try to modify a scene or actor that doesn't exist?
The server will likely return an error or validation failure. Always validate your project structure first, or use the server's tools to list existing scenes and actors before attempting modifications.
