Your Question

Like the title suggests, I'd like to know if there is a standard way to query for an MCP server authentication URL (or maybe the ProtectedResourceMetadata as a whole) before invoking McpClientFactory.CreateAsync.
The way I found to override this is first to issue an HTTP GET to the URL of the MCP Server and check the www-authenticate header to get the ProtectedResourceMetadata URL but I feel like there should be an easier way, like McpClient.GetProtectedResourceMetadata.
Thanks to the helpers.
