Microsoft Foundry is no longer a place to call models — it is a platform for hosting, grounding, governing and operating agents. A working architecture guide to prompt and hosted agents, Foundry IQ, Toolbox, MCP and A2A, model choice and Claude, agent identity and RBAC, private networking, evaluation and Agent 365 — with every capability marked GA, Preview or retiring, and the places Microsoft's own documentation contradicts itself named rather than smoothed over.
A research-grounded enterprise reference architecture for autonomous AI agents: agent identity, task-bound authorization, tool and MCP gateways, memory security, runtime containment, observability, and incident response — with an OWASP agentic Top 10 mapping, a bounded-autonomy model, and a 38-control matrix.
AI services are entering organizations through every door at once. Treating them as enterprise platforms — with identity, data boundaries, logging, and governance — is the difference between adoption and exposure.
Can agentic AI actually run security operations? The interesting problem is not the triage decision — it is everything around it: authority, tenant isolation, evidence, approval, and audit. This is the full target architecture, published as something you can click through.
