How do I use Ubuntu SSH MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Ubuntu SSH MCP Server Check system info on prod" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Requirements

Node.js 18+
Claude Code (npm install -g @anthropic-ai/claude-code)

Installation

# 1. Clone / copy this folder somewhere permanent
cd ~/ubuntu-ssh-mcp
npm install

# 2. Register with Claude Code (global scope — available in all projects)
claude mcp add ubuntu-ssh-mcp -- node /ABSOLUTE/PATH/TO/ubuntu-ssh-mcp/index.js

# Verify it's registered
claude mcp list

Alternative: Project-level config

Create or edit .mcp.json in your project root:

{
  "mcpServers": {
    "ubuntu-ssh-mcp": {
      "command": "node",
      "args": ["/ABSOLUTE/PATH/TO/ubuntu-ssh-mcp/index.js"]
    }
  }
}

Usage Examples

Once Claude Code is running with the MCP server connected, just talk to it:

> Connect to my server at 192.168.1.10 as ubuntu using my key at ~/.ssh/id_rsa, call it "prod"

> Show me the system info for prod

> Check what security updates are available on prod

> Run a full security audit on prod

> Harden the SSH config on prod — make sure I have key auth working first

> Enable UFW on prod and allow only ports 22, 80, and 443

> Show the last 100 lines of the nginx error log on prod

> List all users on prod and check if any have unexpected sudo access

> Install fail2ban on prod and check the sshd jail status

Security Notes

Use SSH key auth — avoid passing passwords where possible.
sudo_password is passed as a parameter; Claude Code stores no secrets. Use NOPASSWD sudoers for a CI/automation account if you prefer not to pass passwords.
harden_ssh will restart sshd — ensure key-based auth is working before calling it or you may lock yourself out.
Connections persist for the life of the Claude Code session and are cleaned up on exit.
The server runs locally via stdio — no network ports are opened by the MCP server itself.
