Introducing the Microsoft Copilot harness in Foundry Agent Service
Microsoft launches managed Copilot harness in Foundry Agent Service for complex agent workflows
“With the Microsoft Copilot harness in Foundry Agent Service, we had a solution running in less than a week, allowing us to focus on design and capabilities instead of the infrastructure underneath it.”
Microsoft has released the Copilot harness in Foundry Agent Service in public preview, providing developers a fully managed agent execution environment with reusable skills, MCP tool connectivity, subagent delegation, and source-controlled definitions. It also announced general availability of long-running resilience for hosted agents. This matters because it commoditizes the undifferentiated 'agent loop' infrastructure, shifting enterprise AI development focus toward domain expertise and evaluation rather than orchestration plumbing.
