tv_mute · Smart Home Control MCP Server MCP: Risk & Policy

WHAT IT DOES

What tv_mute does on Smart Home Control MCP Server

AI agents invoke tv_mute 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_mute needs a policy

This tool sends a command to an external device (Android TV via ADB) to toggle its mute state. It triggers a real-world hardware action rather than simply reading or writing data. The blast radius is medium since misuse could disrupt audio on a TV but is easily reversible by toggling again.

From the tool's definition Mute/unmute TV — triggers an external operation on a physical Android TV device via ADB
