Capture a screenshot of the Game View. The screenshot is saved on the next frame render.
AI agents call unity_screenshot_game to retrieve information from Unity MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool captures and retrieves visual output from the Game View—a read-only operation that observes the current rendering state. It does not modify project data, execute game logic beyond normal rendering, create/delete assets, or trigger external actions with side effects. The screenshot is saved as data but no game state is altered.
From the tool's definition Tool name 'unity_screenshot_game' and description 'Capture a screenshot of the Game View. The screenshot is saved on the next frame render' indicate this retrieves visual data without modifying game state or assets.

"unity_screenshot_game": {}
}
