Read the current clipboard text content
AI agents call desktop_clipboard_read to retrieve information from MCP Desktop Tools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves clipboard data; it performs no write, delete, execute, or financial operations. The action is passive and non-destructive. Severity is low because clipboard content is typically user-visible and reading it poses minimal risk compared to other desktop automation tools on this server (like desktop_clipboard_write or browser_click which could trigger unintended actions).
From the tool's definition Tool name 'desktop_clipboard_read' and description 'Read the current clipboard text content' indicate a read-only operation that retrieves data from the system clipboard without modification or side effects.
