SSE MCP support is deprecated. Will Metals move to something else?

[ckipp01]

In some of the latest releases of claude code CLI I noticed that Metals has completely stopped working and there is no request even sent to the server. While I knew that the Claude Docs say SSE servers are deprecated they didn't say there were unsupported. However after digging a bit into the logs I finally found:

[ERROR] MCP server "metals" Connection failed: SSE MCP servers are currently not supported in native builds.

So it looks like in some of their apps they've fully removed support for SSE. I see quite a few issues about this in the Claude repo, but a lot of people are just saying it's been deprecated in the MCP protocol for quite some time and reference this PR.

I have no idea if other tools will start to also drop SSE support, but I know that Claude dropping it in various places has kickstarted various servers switching. Has this been though about at all?

Thanks for finding that one! We'll need to switch then, but I hate how they always drop something and we need to adjust. I will probably have to drop the trace.mcp.json now, since the MCP library made it impossible to use anymore in the newest version
