HTTP mount for an OAuthProxy (basic/authorization §Authorization Server Discovery + §Dynamic Client Registration; RFC 8414 / RFC 7591 / RFC 9728).
End-to-end test of the server->client request round-trip between this SDK's own McpServer and McpClient, over a real Streamable HTTP transport.
mcp.transport — opt-in transport wiring for the MCP SDK.
import mcp; exposes only the curated public API (protocol types, McpServer / McpClient, the UDA / reflection layer, and the error builders). Server / client transport plumbing — stdio, Streamable HTTP, the SSE channel, session management, the OAuth-proxy mount, and the draft transport helpers — is brought in explicitly with import mcp.transport;.
