CyberRescue MCP server

CyberRescue is a small helper you run on your own computer that lets Claude look inside your Docker containers. It is handy if you use Docker and want help figuring out why a container crashed, is leaking memory, or is misbehaving. Instead of switching between terminals and copy-pasting logs, you just ask Claude in plain words.

What this MCP server does

You ask Claude something like "why did my-app crash?" and it decides which of the three tools to use. It can pull the last chunk of logs from a container, take a live memory and CPU snapshot, and run a shell command inside the container. The helper talks to Docker on your computer, gets the answer, and hands it back to Claude. Claude then explains what it found and suggests a fix, all in the same chat.

What you can do with it

• Read the latest logs from a container by name or ID
• Filter logs by keyword or by time
• Check live memory and CPU usage of a container
• See the top processes eating memory inside a container
• Run a diagnostic shell command inside a container
• Ask Claude to explain what likely went wrong

Try asking your AI

• “Debug the container named my-app: show me the last 150 log lines and its memory usage.”
• “Which process is eating the most memory inside leaking-node right now?”
• “Run printenv DATABASE_URL inside broken-flask and tell me if it is set.”
• “Look at crashed-nginx logs and tell me why it will not start.”

What it gives back to you

You get the actual log lines, memory and CPU numbers, and the output of any command it ran, shown right in the chat. Claude usually follows up with a short explanation of what it thinks went wrong and what to try next. Logs are capped at 50KB, so very long logs come back trimmed with a note that they were cut.
