Choose around the work the agent must do

The Customer Zero guide positions Agent Builder in Microsoft 365 Copilot as a starting point for lightweight retrieval from Microsoft 365 content and web sources. Copilot Studio adds connectors, actions and workflow automation. Foundry and developer tools offer more architectural control and custom orchestration.

Microsoft published an internal deployment guide distinguishing Microsoft 365 agent creation, Copilot Studio and Foundry. It matches simpler knowledge tasks, low code workflows and developer-built systems to different tools, with governance based on risk.

Microsoft ties governance to the scope of access and action, rather than treating every agent as equally risky. A knowledge helper and an agent that updates operational records need different controls, even if both start with a conversational interface.
