SSH MCP server (cygnus-ssh-mcp)

This is a helper that connects your AI assistant to your own remote servers over SSH, the same way you would log in yourself. You can ask it to check disk space, edit a config file, or restart a service, and it does it on the actual machine. It is handy for anyone who looks after a few servers, whether Linux, macOS, or Windows.

What this MCP server does

You tell your AI something like "check disk space on my web server". Your AI uses this helper, and the helper logs into that server over SSH using the details you saved. It runs the commands or edits the files you asked about, then sends the results back. Your AI reads those results and explains them to you in plain words, right in the chat.

What you can do with it

• Check disk space, memory, uptime, and recent logs on a server
• Edit a config file line by line and show you the difference
• Upload a file, extract it, and restart a service
• Start a command in the background and fetch its output later
• Run commands with sudo when you need admin rights
• Look at running processes on a Windows SSH host
• Create or extract archives and work with folders

Try asking your AI

• “Connect to PROD and tell me about the machine, hardware, status, everything”
• “Edit /etc/nginx/nginx.conf and change worker_connections to 2048”
• “Find all .log files larger than 100MB in /var/log”
• “Start this command in the background and fetch the output later”

What it gives back to you

You get back answers in the chat: lists of files, summaries of what is running, numbers like free disk space, and the output of commands. If it changed or created something, it tells you what it did. For file edits, it can show you the difference before and after. Everything is explained in normal sentences, not raw machine output.
