WHAT IT DOES

What hello does on Nitrostack

AI agents call hello as a supporting operation in Nitrostack workflows.

RISK

Why hello is rated Low

This tool simply greets someone. It does not read data from a system, write or modify anything, execute code, delete data, or involve financial transactions. It is a trivial conversational/demo action with no meaningful side effects or blast radius.

RECOMMENDED RULE

The rule that runs hello safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nitrostack, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hello, this is the rule to start with:

hello Rate-limited

hello gets a rate cap, and everything else on the server is denied unless you say otherwise.
