The build-mcp-app skill streamlines the creation of 'MCP apps'—enhanced MCP servers that serve interactive UI resources directly within the chat interface. It provides the patterns and code structures needed to implement complex components like searchable pickers, live dashboards, and confirmation dialogs, enabling a more intuitive interaction model than plain text alone. This skill handles the complexities of the apps SDK, including bidirectional communication via the App class and secure iframe sandboxing.
