List support messages.
AI agents call dual_list_support_messages to retrieve information from DUAL MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries support messages without creating, modifying, deleting, or executing any actions. It is a straightforward read operation with minimal security risk. The low severity reflects that support messages are typically not sensitive operational data and listing them has no destructive or financial impact.
