# Creating MCP Apps

Those are conversational experiences that extend AI assistants through tools and custom UI widgets. They're built as MCP servers invoked during conversations.

⚠️ The app is consumed by two users at once: the **human** and the **AI Assistant LLM**. They collaborate through the widget—the human interacts with it, the LLM sees its state. Internalize this before writing code: the widget is your shared surface.
