Gets currently active/logged-in users
AI agents call mikrotik_get_active_users to retrieve information from MikroTik MCP 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 active user sessions on the MikroTik RouterOS device. It performs no modifications, creates no resources, executes no commands, and causes no side effects. The blast radius of misuse is minimal—an unauthorized user could discover who is logged in, which is informational but does not compromise system integrity or enable further attacks directly.
From the tool's definition Tool name 'mikrotik_get_active_users' and description 'Gets currently active/logged-in users' indicates a query operation that retrieves status information without modifying any state.
