WHAT IT DOES

What list_server_groups does on API-Central

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

Why list_server_groups is rated Low

This tool queries and returns a list of existing authentication server groups. It performs data retrieval without creating, modifying, deleting, or executing any operations. The bounded default scope further limits exposure. This is a straightforward read operation with minimal risk if misused by an AI agent.

From the tool's definition Tool name 'list_server_groups' and description 'List RADIUS/TACACS auth server groups' indicate a retrieval operation with no side effects.

RECOMMENDED RULE

The rule that runs list_server_groups safely

list_server_groups Allowed

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