Display current clipboard contents
AI agents call show_clipboard to retrieve information from Cut-Copy-Paste Clipboard Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The action is purely informational, making it a Read category tool with low severity, as exposure poses minimal risk even if misused by an AI agent.
