AI agents call get_clipboard_stats to retrieve information from Maccy Clipboard MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves clipboard usage statistics without modifying, deleting, or executing any operations. It is purely informational and falls clearly into the Read category.
