cond_clipboard_paste · TermPipe MCP: Risk & Policy

WHAT IT DOES

What cond_clipboard_paste does on TermPipe MCP

AI agents invoke cond_clipboard_paste to trigger actions in TermPipe MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why cond_clipboard_paste needs a policy

This tool performs an action that directly manipulates the active window through simulated keyboard input. While the action itself (pasting) is not inherently destructive, it falls under Execute because: (1) it triggers external operations (sending Ctrl+V to an active window), (2) the effects depend on external state (clipboard contents and active window), and (3) when combined with terminal access, it can execute…

From the tool's definition Tool description states it will "Trigger Ctrl+V to paste current clipboard content into active window." This executes a keyboard action that interacts with the active application window.
