Display information about logon sessions. Shows detailed information about the current or specified logon session.
AI agents call rubeus_logonsession to retrieve information from Rubeus 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 and displays information about logon sessions. While it operates in a security-sensitive domain (Kerberos/Windows authentication), the action itself is purely informational - it queries and presents existing session data without modifying state, executing code, or triggering external operations. The read-only nature and lack of side effects place it firmly in the Read category.
From the tool's definition Tool name 'rubeus_logonsession' and description 'Display information about logon sessions' - uses display/show verb indicating data retrieval without modification or execution of privileged operations.
