Class MissingMcpTransportSession

java.lang.Object
io.modelcontextprotocol.spec.MissingMcpTransportSession
All Implemented Interfaces:
McpLoggableSession, McpSession
public class MissingMcpTransportSession extends Object implements McpLoggableSession
A McpLoggableSession which represents a missing stream that would allow the server to communicate with the client. Specifically, it can be used when a Streamable HTTP client has not opened a listening SSE stream to accept messages for interactions unrelated with concurrently running client-initiated requests.

      T - the type of the expected response
      Parameters:
      method - the name of the method to be called on the counterparty
      requestParams - the parameters to be sent with the request
      typeRef - the TypeReference describing the expected response type
      Returns:
      a Mono that will emit the response when received

    • sendNotification

      public reactor.core.publisher.Mono<Void> sendNotification(String method, Object params)

      Sends a notification to the model client or server with parameters.

      Similar to McpSession.sendNotification(String) but allows sending additional parameters with the notification.

      Specified by:
      sendNotification in interface McpSession
      Parameters:
      method - the name of the notification method to be sent to the counterparty
