Multiple server instances

[jtabox]

Hi,
I'm not 100% sure if the following issue is this mcp server's or Docker's MCP Toolkit's, if it doesn't belong here let me know and I'll post it there.
It happens only with this mcp server in any case.

So using this server with Docker's new MCP Toolkit, it seems that when a new instance is created (e.g. after a reboot, potentially when a client e.g. VS Code is restarted) the previous containers aren't being removed. So after some reboots and a couple VS Code restarts, the list of containers looks like this:

Their logs are pretty much the same too, so I can't figure out what each container is used for:
