GB Studio MCP Server
Let your agent create and edit GB Studio Game Boy projects—scenes, actors, assets—and run validation without clicking through the desktop UI for every change.
Overview
GB Studio Claude MCP is a MCP server for the Build phase that exposes tools to create, edit, and validate GB Studio Game Boy projects from a coding agent.

- Tools to create and modify GB Studio projects: scenes, actors, assets, and project validation
- Optional CLAUDE_API_KEY for /claude-key related endpoints documented in server schema
- Targets retro solo devs shipping small Game Boy titles with Claude-assisted iteration
- Validation tooling helps catch project issues before export/build—not a replacement for GB Studio runtime testing on har

- Transport: stdio
Community signal: 10 GitHub stars.
What problem does it solve?
Indie GB Studio developers waste context switching between the agent and the GB Studio UI for every scene, actor, and asset tweak.
Who is it for?
Solo retro game makers already using GB Studio who want Claude Code or Cursor to drive project edits programmatically.
Skip if: Builders who do not use GB Studio or who only need generic Unity/Godot MCP—not Game Boy-specific workflows.
What do I get? / Deliverables
After registration, your agent can manipulate GB Studio project structure and run validation through MCP while you stay in the terminal or IDE.
- Agent-callable MCP tools for GB Studio project create/modify operations
- Validation passes over project structure before you ship a build
- Faster iteration on scenes, actors, and assets from the agent session
Recommended MCP Servers
Journey fit
GB Studio work is product construction: scenes, actors, and assets are core build-phase deliverables before you ship a ROM or itch release. Agent-tooling fits because the value is MCP tools that extend your coding agent into a specialized game-authoring environment, not generic frontend CSS.
How it compares
GB Studio project MCP integration, not a standalone game engine skill or ROM publishing service.
Common Questions / FAQ
Who is gbstudio-claude-mcp for?
It is for solo developers building Game Boy games in GB Studio who want MCP tools so Claude or similar agents can edit scenes, actors, assets, and validate projects.
When should I use gbstudio-claude-mcp?
Use it during active GB Studio development when you want agent-driven project changes, bulk edits, or validation checks without manual UI repetition.
How do I add gbstudio-claude-mcp to my agent?
Install gbstudio-claude-mcp from npm (v1.0.4), configure a stdio MCP server in your host pointing at the package binary, set CLAUDE_API_KEY only if you use the optional /claude-key endpoints, and ensure GB Studio is available on your machine for export and playtest.
