[Licensing] List license servers.
AI agents call licensing_list_servers to retrieve information from CyPerf 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 information about license servers without creating, modifying, deleting, or executing operations. It is a straightforward read operation that gathers configuration or status data. The blast radius of misuse is minimal—an AI agent querying this would only gain visibility into licensing infrastructure, posing no direct risk to system integrity or operations.
From the tool's definition Tool name 'licensing_list_servers' and description 'List license servers' indicate a query/retrieval operation with no data modification or side effects.
