Expected Behavior

add a configuration option that can ignore illegal format jsonrpc

Current Behavior
just break when meeting the illegal behavior.

Context
there is no guarantee that there are no interfering messages when connecting to spring ai mcp server using stdio.
Using the config, we can just skip the error but have a clear log for developers.
pls look at this issue on spring-ai
spring-projects/spring-ai#3769
