MCP Apps for Claude : Build interactive UI inside the conversation
Overview
Build interactive apps that live inside Claude's conversations.
Ask an AI assistant whether a meeting room is free and you usually get a sentence. With an MCP App, you get a card instead: the room, the next free half hour, and a Book button that works right there in the chat. MCP Apps for Claude shows you how to build that kind of interface, from the first tool to a listing in Claude's connector directory.
The book follows one real app, Snug, a meeting-room booking connector, from a text-only MCP server to a polished, tested app that runs in claude.ai, in Claude Desktop and in the Claude Android app. Every code example is cut from a real, tested file, and every screenshot was taken in Claude.
