Hi @liugddx, @sivaprasadreddy,

unfortunately, we ran into last minute issues with this PR which interferes with other ObjectMapper definitions in Spring AI.
This is just a heads up to let you know that the fix will not be part of M4, but hopefully RC1.

We're trying to find the best way to make the mcp ObjectMapper correctly configured, yet still overridable by users and ALSO not messing with potential other ObjectMappers in their app (be them provided by Boot or not).
