[RFC] UI Component Integration in MCP: Client-Server Capabilities

[olaservo]

This could include:

• MIME type support for specific UI components
• Capability negotiation for adaptive responses
• Define basic UI building blocks (like mobile apps)

Other considerations and suggestions raised so far:

• Alternative content support: Servers emit multiple content parts with different mimetypes
• Dynamic capability changes: Allow clients to modify capabilities on the fly
• Fallback mechanisms: for example, ui-basic for simple interfaces, ui-webview for rich content
