WHAT IT DOES

What tengu_insider_clusters does on Tengu

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

RISK

Why tengu_insider_clusters is rated Low

Even though tengu_insider_clusters 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.
