Summer Engine MCP guide
How to make games in Claude Code with Summer Engine
Use Claude Code as the agent and Summer Engine as the real game engine for playable projects, local debugging, and exportable builds. Summer Engine is the desktop game engine; Claude Code is the agent that drives it through MCP.
Summer is free for MCP use
Download the desktop engine and connect it to your agent. You are not paying Summer for the AI calls your existing subscription already covers.
Open Claude Code
Use the AI editor you already have. The setup command writes the MCP config and installs the Summer game-dev skills.
Launch a real game
The agent writes code. Summer Engine shows the game, runs Play mode, and exports projects for Steam, desktop, mobile, and console pipelines.
Why this matters
Claude Code writes with your subscription. Summer Engine shows the game.
A chat agent alone can write files. With MCP, Claude Code gets tools for the running game engine, so it can inspect the project, run commands, and make changes that become playable inside Summer.
