Remove items from the current user's library. Auto-chunks at 50 items per request.
AI agents call remove_from_library to permanently remove resources in Spotify MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

While not as critical as deleting account data or financial records, it permanently alters the user's personal collection.
