For now, I have chosen packet for the trial server even though the cost is high. The specs are good (even for entry level containers) and I got some credits to work with initially.

So I setup the ssh keys for login and got to work.

The github repository for parsey mcparseface and syntaxnet is available here and it also lists out the steps required to setup syntaxnet and get it working. They also provide a demo shell script file which accepts the input at stdin and passes it to a python script named parser_eval. The output which is an ascii tree of the pos tagged statement is posted to stdout.
