I guess it depends if you want to restrict an agent to a set of protocols or let it go wild.
I think in most use cases and agent would need just https and dns, both which can be MiTM monitored. In other some cases maybe also one or more of SSH, redis, MySQL, Postgres etc.
But YOLOing and letting it to connect to anything is probably not needed.

Thanks for your comment - MCP Defender sits between the MCP client and server, it doesn't need to worry about the protocols that the server communicates with to other services.
