[wildfly-dev] Re: Promote MCP server features to default stability level

Hi, We have made good progress on this proposal. The feature pack has been updated to be at the experimental stability overall. Dimitris and Emmanuel have implemented a lot of the remaining features for the 2025-11-25 MCP prototocol too. We’re not ready yet to promote the MCP server features at the default stability level. We rely on a Java library for MCP annotations and API that is not final and there is a new MCP protocol around the corner. We need to have a plan to implement this new protocol in a stable manner before we can really provide it as a stable feature… Still, I think we are at the point where this project can move from the wildfly-extras to the wildfly organization. This transfer is transparent for users but this has a few impact for developers: * It will change the nexus deployment process * It will allow us to publish documentation for this feature pack at docs.wildfly.org I’m planning to transfer the project later today. Github handles nicely the redirection but I’ll send another message when the transfer is done so that we can all point directly to the repo in the github.com/wildfly organization. After this transfer, we will be able to release a new version of the feature pack. It *will* be a breaking change as users will have to provision and run WildFly at the experimental stability level (and the API as been updated for some advanced MCP server features such as elicitation).
