When does this happen?

IF When setting up the filesystem MCP server, dynamic directory updates without server restart are required.

How others solved it

THEN Use MCP Roots protocol instead of command-line arguments. Implement client support for roots/list and roots/list_changed notifications so that allowed directories can be updated at runtime. If the server starts without command-line arguments and the client does not support roots, initialization will fail.
