ext-apps vs ruby-sdk

ext-apps: MCP Apps enable developers to build interactive user interfaces like charts, forms, and dashboards for Model Context Protocol (MCP) tools. These UIs render directly within compliant chat clients such as Claude and ChatGPT, enhancing the conversational experience with dynamic visual elements.; ruby-sdk: The MCP Ruby SDK provides official support for building and interacting with Model Context Protocol servers and clients. It offers a comprehensive set of features including JSON-RPC handling, tool/prompt/resource management, and various transport layers, facilitating the integration of LLM-powered applications.
