Get clipboard items from specific application
AI agents call get_items_by_app 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 history entries filtered by application source. It queries existing data and returns results with no side effects, data modification, deletion, or external execution. This is a straightforward read operation with minimal risk unless the clipboard contains sensitive data, but the tool itself performs no destructive or dangerous actions.
