WHAT IT DOES

What tv_press_key does on Smart Home Control MCP Server

AI agents invoke tv_press_key to trigger actions in Smart Home Control MCP Server. 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 tv_press_key needs a policy

This tool triggers an external operation on a physical device (TV) by simulating remote key presses via ADB. It executes commands that affect the state of a real-world device. Effects are generally reversible (e.g., pressing a key can be countered), so it doesn't rise to Destructive, but it does execute external operations with real-world impact.
