Description
1.0.0-M7 版本：
client 采用sse 方式连接上 mcp server，可以正常运行；这个时候重启 mcp server， client 端就不会重连 mcp server，导致一直报错
reactor.core.Exceptions$ReactiveException: java.util.concurrent.TimeoutException: Did not observe any item or terminal signal within 20000ms in 'source(MonoCreate)' (and no fallback has been configured)
at reactor.core.Exceptions.propagate(Exceptions.java:410)
at reactor.core.publisher.BlockingSingleSubscriber.blockingGet(BlockingSingleSubscriber.java:102)
怎么设置重连mcp server？

Research direction
Start by reproducing the SSE client connection, restart the MCP server, and capture the resulting timeout. Then inspect the MCP client’s reconnect handling and available configuration; done means the previous client automatically reconnects after a server restart without continuing to time out.
