+A demonstration of how to use the MCP Python SDK as a private gateway with optional API key authentication over streamable HTTP or SSE transport with custom extensions for private gateway connectivity (SNI hostname support).
 
 ## Features
 
-- Multiple authentication options:
-  - OAuth 2.0 authentication with PKCE
-  - API Key authentication (Bearer token or custom header)
-  - No authentication
+- Optional API Key authentication (Bearer token or custom header)
 - Supports both StreamableHTTP and SSE transports
 - Custom extensions for private gateway (SNI hostname) - **Both transports**
 - Can combine authentication + extensions (for authenticated private gateway)

-- **Server hostname**: The hostname for SNI (Server Name Indication) used in private gateway setup (default: mcp.deepwiki.com)
+- **Server URL**: The full URL of your MCP server (default: https://localhost:8081)
+  - If you provide a URL, it will be used directly
+  - If you press Enter (empty), you'll be prompted for individual components:
