WHAT IT DOES

What hello does on Terminal Guardian

AI agents call hello as a supporting operation in Terminal Guardian workflows.

RISK

Why hello is rated Low

The name and description suggest a trivial greeting or test/ping endpoint with no apparent side effects. However, on a terminal-access server, even benign-looking tools could have hidden effects; the description provides no detail. Classifying as Other with low confidence due to the uninformative description.

From the tool's definition Tool name is 'hello' and description is 'Say hello' — entirely uninformative about any real action.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs hello safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Terminal Guardian, 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.
