MCP Apps: Give the Model Data, Give the User a UI — Dustin Mihalik, Indeed
Dustin Mihalik from Indeed demonstrates how to build AI apps with good interfaces without compromising the model's reasoning ability.
The problem is that when adding a nice widget that displays results directly, the model often stops exploring—it sees the answer on screen and halts. He presents three rules: everything shown to the user must also be sent to the model as data, the tool must inform the model that an interface exists, and most importantly—separate data processing from presentation. At Indeed, they use a search tool that the model can call freely, plus a separate rendering widget that takes a list of IDs, allowing the model to search hundreds of jobs, filter to five, and display only those.
