Get information about the screen: logical dimensions, physical dimensions,
AI agents call get_screen_info to retrieve information from Computer Use MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries display configuration. It has no side effects, cannot be abused to cause significant harm, and only returns informational data about the system's screen setup. The blast radius of misuse is minimal since an AI agent gaining screen dimensions poses no direct security or operational risk.
