Are agents really killing UI?

Although AI agents are increasingly interacting with software through APIs, tool calls, SQL, and Model Context Protocol (MCP) servers rather than traditional screens, user interfaces remain important for the humans directing, reviewing, and correcting those agents. Product teams are encouraged to support both agent and human entry points by enabling autonomous signup, authentication, setup, documentation access, and core actions for agents while providing clear human-facing views of progress, state, approvals, changes, and next steps. The text argues that agent experience should be treated as a product discipline, with observable tool calls, client attribution, failure tracking, and intent data revealing unmet needs that conventional UI analytics may miss. Rather than making interfaces obsolete, agents shift UI design toward decision surfaces such as diffs, approval workflows, undo controls, action histories, and orchestration dashboards, where people can quickly understand and govern automated work. The proposed future is therefore hybrid: robust headless infrastructure expands a product’s reach through agents, while effective, visually legible interfaces provide the trust, oversight, and usability that human users still need.
