I don't know if you understand the role the LLM is playing here. The mechanism used to execute the command is not the relevant thing. The LLM autonomously executing commands has intelligence, it's not just a shell script. If I ask it to do a task, and it runs into an issue... LLMs like Claude can recognize the problem, and find a way to resolve it. Script failed because of a missing dependency, it'll install it. Need a config change, it'll do it. The SSH mcp is just the interface for the LLM to do the work.

You can give an LLM a github repo link, a fresh VPC, and say "deploy my app using nginx" and any other details you need... and it'll get it done.
