Check the current authentication status with Microsoft Graph API
AI agents call check-auth-status to retrieve information from Outlook Assistant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only check of authentication status. It retrieves information about the current authentication state but does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal—an agent could at most learn whether authentication is valid, which does not expose sensitive data or enable harmful actions. Therefore, it is classified as Read with low severity.
From the tool's definition Tool name 'check-auth-status' and description 'Check the current authentication status with Microsoft Graph API' indicate a query operation that retrieves authentication state information without modifying any data or triggering external actions.
