-When a tool cannot proceed without first completing a URL-mode elicitation (for example, when third-party OAuth authorization is needed), and calling `ElicitAsync` is not practical (for example in <xref: ModelContextProtocol.AspNetCore.HttpServerTransportOptions.Stateless> is enabled disabling server-to-client requets), the server may throw a <xref:ModelContextProtocol.UrlElicitationRequiredException>. This is a specialized error (JSON-RPC error code `-32042`) that signals to the client that one or more URL-mode elicitations must be completed before the original request can be retried.
