AI Tools with Interactive Interfaces
Claudia fully supports MCP-UI — the official MCP Apps standard for interactive AI tool interfaces. Instead of plain text, your MCP tools can render rich HTML UIs directly inside the chat window.
Beyond Text — Full UI in Chat
MCP-UI tools use the ui:// resource URI scheme to deliver interactive HTML interfaces. Claudia renders them in secure sandboxed iframes with live two-way messaging between the UI and the AI.
