What billing_status does on Hermoso
AI agents call billing_status to retrieve information from Hermoso without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why billing_status is rated Low
This tool retrieves and displays billing status information about the account. It performs a read-only query with no side effects, modifications, or financial transactions. The severity is low because viewing account status poses minimal risk even if accessed by an AI agent, though information disclosure could be a minor concern in isolated scenarios.
From the tool's definition Tool name 'billing_status' and description 'Show this account' indicates retrieval of account billing information without modification or financial operations.
Attacks that exploit this kind of access
The rule that runs billing_status safely

billing_status is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Hermoso, apply this rule, and every billing_status call is checked against it from then on.
