isNotificationForLevelAllowed

public boolean isNotificationForLevelAllowed(McpSchema.LoggingLevel loggingLevel)

从接口复制的说明: McpLoggableSession

Allows checking whether a particular logging level is allowed.

指定者:

isNotificationForLevelAllowed 在接口中 McpLoggableSession

参数:

loggingLevel - the level to check

返回:

whether the logging at the specified level is permitted.

sendRequest
