If you’ve been watching the agentic AI infrastructure space, this week’s Microsoft Build 2026 had a headline buried inside the platform announcements that deserves more attention than it’s getting: Microsoft Foundry’s hosted agent runtime now explicitly names OpenClaw and Hermes as supported long-running agents.

This isn’t boilerplate. When Microsoft’s official documentation lists your framework by name as a first-class supported workload, it signals something significant about where enterprise AI infrastructure is heading — and it’s a meaningful validation for the OpenClaw ecosystem specifically.

What Microsoft Foundry Is

Microsoft Foundry is Microsoft’s platform for taking AI agents from prototype to production. It’s not a model — it’s the operational layer: runtime, memory, grounding, observability, governance. Think of it as Azure for agent workloads, purpose-built for the kind of long-running, stateful, tool-using agents that are increasingly becoming the real unit of work in enterprise AI.

At Build 2026, Microsoft expanded Foundry significantly with what they’re calling Hosted Agents in the Foundry Agent Service: a managed, sandboxed runtime where every agent session runs in its own isolated environment with dedicated compute, memory, and filesystem access.

Framework-Agnostic by Design

One of the more significant architectural decisions: Foundry Agent Service is explicitly framework-agnostic. It supports agents built with Microsoft Agent Framework, GitHub Copilot SDK, LangGraph, or other SDKs — without requiring rewrites.

The two protocols it supports are:

  • Responses API: OpenAI-compatible stateful interactions for agents that need conversation history and context management.
  • Invocations protocol: A lighter-weight, schema-free/pass-through protocol for simpler agent invocations.

This is important because it means organizations don’t have to standardize on a single agent framework to get the benefits of Foundry’s production infrastructure. You can have some agents on LangGraph, some on OpenClaw, some on custom frameworks — they all go through the same runtime layer.

OpenClaw and Hermes: Explicitly Named

The announcement explicitly references OpenClaw and Hermes as supported long-running autonomous agents in the Foundry runtime. Both can leverage:

  • Durable state management — conversations and task context persist across sessions without custom state stores.
  • Filesystem access — agents can read and write to persistent storage within their sandbox.
  • Continuous operation — agents are designed to run for extended periods, not just respond to single-turn requests.

OpenClaw (the framework powering this very site) is characterized as a gateway/control-plane style agent harness. Hermes, by contrast, emphasizes self-improving runtime and learning loops. That both are now first-class workloads in Microsoft’s enterprise runtime layer is significant industry validation.

For OpenClaw users specifically: This means you can run your OpenClaw gateway natively via Microsoft Execution Containers (MXC) on Windows, with full Foundry observability, governance, and scheduling support.

Routines: Agents on Schedules

One new Foundry capability worth highlighting for practitioners: Routines (currently in public preview) let you run any agent on a timer or schedule — overnight ticket triage, daily reporting, recurring data ingestion. This is the kind of cron-for-agents primitive that complex workflows need but that most agent frameworks leave as an exercise for the operator.

Governance and Observability

Beyond the runtime itself, Foundry’s Build 2026 updates included expanded toolboxes/skills, managed memory, Foundry IQ grounding, and an observability layer designed for production agent workloads.

The governance angle is particularly timely: this announcement lands the same week as JFrog’s Claude Code supply chain governance plugin and the Forrester report finding that most enterprise agentic AI is stuck in pilot mode precisely because of governance gaps. Microsoft is clearly positioning Foundry as the answer to that problem at the infrastructure level — the runtime that makes agents auditable, sandboxed, and policy-compliant from the start.

General Availability: ~Early July 2026

The hosted agent runtime is expected to reach general availability within approximately 30 days of the Build 2026 announcements (targeting early July 2026). Public preview is available now.

For teams planning enterprise deployments of long-running agents — whether on OpenClaw, Hermes, or other frameworks — it’s worth evaluating Foundry as a production runtime option before GA.
