Nuxt MCP Toolkit now supports MCP apps

Tools built with the defineMcpApp macro return interactive HTML that Claude and ChatGPT render inline instead of plain text.
Vercel's Nuxt MCP Toolkit now supports MCP apps, letting agent tools return interactive HTML that MCP clients like Claude and ChatGPT render inline instead of as plain text.
Tools are declared with a defineMcpApp macro. Inside the UI, the useMcpApp composable reads pre-hydrated data, triggers follow-up prompts, or calls other tools. Each Vue single-file component is bundled into a self-contained HTML file at build time and served from the app's MCP endpoint.
