WHAT IT DOES

What iac_mcp_send_keystroke does on Iac

AI agents invoke iac_mcp_send_keystroke to trigger actions in Iac. 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 iac_mcp_send_keystroke needs a policy

Sending keystrokes to applications is an Execute-level action because it triggers arbitrary operations within the target application depending on what key/modifier combination is sent. Keystrokes can trigger any application function including saving, deleting, submitting forms, executing commands (e.g., Cmd+Q to quit, Cmd+A+Delete to delete all, etc.).
