    • sessionId

      public Optional<String> sessionId()
      Description copied from interface: McpTransportSession
      In case of stateful MCP servers, the value is present and contains the String identifier for the transport-level session.
      Specified by:
      sessionId in interface McpTransportSession<reactor.core.Disposable>
      Returns:
      optional session id

    • markInitialized

      public boolean markInitialized(String sessionId)
      Description copied from interface: McpTransportSession
      Stateful operation that flips the un-initialized state to initialized if this is the first call. If the transport provides a session id for the communication, argument should not be null to record the current identifier.
      Specified by:
      markInitialized in interface McpTransportSession<reactor.core.Disposable>
      Parameters:
      sessionId - session identifier as provided by the server
      Returns:
      if successful, this method returns true and means that a post-initialization step can be performed

    • addConnection

      public void addConnection(reactor.core.Disposable connection)
      Description copied from interface: McpTransportSession
      Adds a resource that this transport session can monitor and dismiss when needed.
      Specified by:
      addConnection in interface McpTransportSession<reactor.core.Disposable>
      Parameters:
      connection - the managed resource

    • removeConnection

      public void removeConnection(reactor.core.Disposable connection)
      Description copied from interface: McpTransportSession
      Called when the resource is terminating by itself and the transport session does not need to track it anymore.
      Specified by:
      removeConnection in interface McpTransportSession<reactor.core.Disposable>
      Parameters:
      connection - the resource to remove from the monitored collection

    • close

      public void close()
      Description copied from interface: McpTransportSession
      Close and clear the monitored resources. Potentially asynchronous.
      Specified by:
      close in interface McpTransportSession<reactor.core.Disposable>

    • closeGracefully

      public reactor.core.publisher.Mono<Void> closeGracefully()
      Description copied from interface: McpTransportSession
      Close and clear the monitored resources in a graceful manner.
      Specified by:
      closeGracefully in interface McpTransportSession<reactor.core.Disposable>
      Returns:
      completes once all resources have been dismissed
