alexa_text_command · Alexa MCP: Risk & Policy

WHAT IT DOES

What alexa_text_command does on Alexa

AI agents invoke alexa_text_command to trigger actions in Alexa. 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 alexa_text_command needs a policy

This tool executes arbitrary voice-equivalent commands on Alexa devices. Since it simulates spoken commands, it can trigger virtually any Alexa capability — smart home control, shopping, calls, routines, etc. — making it a general-purpose execution interface. The blast radius is high because a misused command could control smart home devices, make purchases, or trigger other sensitive actions.
