Building Scalable Prompt Agents with Microsoft Copilot Harness in Microsoft Foundry

This session demonstrates how to build scalable prompt agents using Microsoft Copilot Harness within Microsoft Foundry. A cupcake ordering agent is used as a practical example to show how adding skills, sub-agents, and MCP servers can handle increasingly complex scenarios without requiring custom infrastructure or container hosting.

■ Core Concepts
- How Microsoft Copilot Harness scales prompt agents by adding skills, sub-agents, and built-in tools
- Types of built-in harness tools, including parallel task handling, web page fetching, and workspace file management
- The role of MCP servers in extending agent capabilities

■ Live Demo: Cupcake Ordering Agent
- Building an agent with instructions, tools, and multiple skills
- Adding a single-order skill, a bulk-order skill using CSV input, and a party-planner skill
- Reviewing and confirming orders through a dashboard

■ Agent Configuration with Azure YAML
- Defining skills, MCP servers, and tools in a YAML file
- Setting up the harness type as GitHub Copilot (preview) within Microsoft Foundry

This session is geared toward developers and AI engineers who want to build and scale prompt agents without managing infrastructure. Viewers will learn how to extend agents with modular skills and MCP servers, and gain a practical understanding of agent configuration in Microsoft Foundry.
