MCP Apps SDK — Enable MCP servers to display interactive user interfaces in conversational clients.
Adaptive MCP — dynamically loads @modelcontextprotocol/ext-apps so interactive MCP app cards can bridge back to the host.
Official @modelcontextprotocol/sdk + @modelcontextprotocol/ext-apps adapter for the SolvaPay MCP toolbox (createSolvaPayMcpServer, registerPayableTool) with ./fetch + ./express subpath exports for runtime-specific OAuth bridges.
