[Licensing] Get the host ID for licensing.
AI agents call licensing_get_hostid 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 a host ID value used for licensing purposes. Host IDs are typically identifiers needed to validate or manage licenses, but fetching this information has no side effects, does not execute code or commands, does not modify data, and does not perform destructive or financial operations.
From the tool's definition Tool name 'licensing_get_hostid' and description 'Get the host ID for licensing' indicate a retrieval operation that queries licensing information without modifying, executing, or deleting anything.
