WHAT IT DOES

What calculator_describe does on Site

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

RISK

Why calculator_describe is rated Low

Even though calculator_describe 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
