SSE_LOCAL=true How should it be used?

[lijiaxing1997]

After entering this command, there is no output of monitoring port information and it is directly executed and ended.

It looks like SSE_LOCAL may have been deprecated in a recent update. Currently, with SSE_LOCAL=true on npm that defaults to [INFO] 2025-09-18T22:58:32.126Z [FastMCP info] Starting server in stateless mode on HTTP Stream at http://localhost:3000/mcp instead of:
