WHAT IT DOES

What demo_tool does on Hamza Agent Hub 252

AI agents call demo_tool to retrieve information from Hamza Agent Hub 252 without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why demo_tool is rated Low

Even though demo_tool 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.

RECOMMENDED RULE

The rule that runs demo_tool safely

demo_tool Allowed

demo_tool is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
