WHAT IT DOES

What category_resolver does on Spotify

AI agents call category_resolver to retrieve information from Spotify without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why category_resolver is rated Low

Even though category_resolver only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE
