unfollow_playlist · Spotify MCP Server MCP: Risk & Policy

WHAT IT DOES

What unfollow_playlist does on Spotify MCP Server

AI agents use unfollow_playlist to create or update resources in Spotify MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Spotify MCP Server environment.

WHY IT NEEDS A POLICY

Why unfollow_playlist needs a policy

Unfollowing a playlist removes the user's association with it, but this is a reversible action — the user can re-follow the playlist at any time. The playlist itself is not deleted or modified. This fits the Write category (reversible modification of user library/social state) rather than Destructive. Severity is medium because it affects the user's library/playlist associations, but can be undone.
