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.

Description copied from interface: McpSession

Sends a request to the model counterparty and expects a response of type T.

This method handles the request-response pattern where a response is expected from the client or server. The response type is determined by the provided TypeReference.

Specified by:

sendRequest in interface McpSession

Type Parameters:

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)

Description copied from interface: McpSession

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

params - parameters to be sent with the notification

Returns:

a Mono that completes when the notification has been sent

public reactor.core.publisher.Mono<Void> closeGracefully()

Description copied from interface: McpSession

Closes the session and releases any associated resources asynchronously.

Specified by:

closeGracefully in interface McpSession

Returns:

a Mono that completes when the session has been closed.

close

public void close()

Description copied from interface: McpSession

Closes the session and releases any associated resources.

Specified by:

close in interface McpSession

setMinLoggingLevel

public void setMinLoggingLevel(McpSchema.LoggingLevel minLoggingLevel)

Description copied from interface: McpLoggableSession

Set the minimum logging level for the client. Messages below this level will be filtered out.

Specified by:

setMinLoggingLevel in interface McpLoggableSession

Parameters:

minLoggingLevel - The minimum logging level

isNotificationForLevelAllowed

public boolean isNotificationForLevelAllowed(McpSchema.LoggingLevel loggingLevel)

Description copied from interface: McpLoggableSession
