WHAT IT DOES

What tv_navigate does on Smart Home Control MCP Server

AI agents invoke tv_navigate 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_navigate needs a policy

Navigation commands on a TV are executable operations that change the device's state and UI (going back, returning home). While not immediately destructive, they represent external system manipulation whose effects depend on the device's current state. This is Execute rather than Write because it directly triggers external commands/operations rather than storing data.

From the tool's definition Tool 'tv_navigate' performs actions on external devices ('Navigate TV (back, home)'), triggering navigation commands to Android TVs via ADB (mentioned in server description). These are active operations with side effects on device state.
