WHAT IT DOES

What list_addons does on EchoRelay

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

RISK

Why list_addons is rated Low

This tool retrieves and queries billing addon information without side effects. The explicit 'Read-only' designation confirms it is a passive data retrieval operation, falling squarely into the Read category with low severity since it poses minimal risk if misused by an agent.

From the tool's definition Tool description explicitly states 'Read-only' and lists only retrieval operations: 'List the optional add-on subscriptions'. No modification, deletion, or external action is performed.

RECOMMENDED RULE

The rule that runs list_addons safely

list_addons Allowed

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

    "list_addons": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect EchoRelay, apply this rule, and every list_addons call is checked against it from then on.
