As far as I can tell, there's no way to connect to a mongodb server via a SOCKS5 proxy.

Are you interested in such a feature?

I can see at least a couple of possible ways to support this:

1. Add explict SOCKS5 support (as an optional feature), which would likely introduce a (optional) dependency on some external socks client implementation.

2. Add support for providing a custom tcp "connect" function in some form in the options. This would not add any dependency, but would still allow users to easily hook in a SOCKS5 proxy, and probably other things too.

If you are interested, I am happy to have a go at implementing one of the above.
