mcp server: get session from exchange

[lambochen]

Expected Behavior

Can obtain the session from exchange (McpAsyncServerExchange/McpSyncServerExchange) because I need to get the session to perform business logic processing when implementing BiConsumer<McpAsyncServerExchange, List<McpSchema.Root>>.

Current Behavior

not support.
