End-to-end agent orchestration flow integrating Microsoft Entra ID, Azure Logic Apps, and Microsoft Foundry with zero-trust authentication and human-in-the-loop approval gates. Requests flow from Teams, APIs, events, or schedules through Entra ID identity verification, then to Logic Apps for orchestration, Microsoft Foundry task agents, and external systems like SAP, ServiceNow, and Salesforce via MCP and REST protocols. Human approvers in Teams or email validate critical decisions before final execution, while Defender, Purview, and OpenTelemetry provide continuous governance, threat detection, and end-to-end observability across all phases. This architecture demonstrates enterprise-grade agent governance with per-agent metrics, token usage tracking, and correlation ID propagation for full auditability and cost attribution.
