skip_to_previous · Spotify MCP Server MCP: Risk & Policy

WHAT IT DOES

What skip_to_previous does on Spotify MCP Server

AI agents invoke skip_to_previous to trigger actions in Spotify 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 skip_to_previous needs a policy

This tool triggers an external operation on Spotify's playback system (changing the currently playing track to the previous one). It is not a simple read, nor does it create/modify stored data or delete anything — it controls playback state, which qualifies as Execute. The blast radius is low as it only affects music playback.
