Search and analyze Azure AD unified audit logs for security events, user activities, and compliance monitoring.
AI agents call search_audit_log to retrieve information from Microsoft 365 Core MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and queries audit log data for monitoring and compliance purposes. It retrieves historical security events and user activities without creating, modifying, deleting, or executing any operations. While access to audit logs may be sensitive, the tool itself performs only read operations with no side effects or destructive capability.
