Overview

Description from the maker (original English)

MCP server for read-only Linux system administration, diagnostics, and troubleshooting

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other
  • You need to fill in: LINUX_MCP_KEY_PASSPHRASE

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: LINUX_MCP_USER, LINUX_MCP_SSH_KEY_PATH, LINUX_MCP_KEY_PASSPHRASE, LINUX_MCP_SEARCH_FOR_SSH_KEY, LINUX_MCP_COMMAND_TIMEOUT, LINUX_MCP_VERIFY_HOST_KEYS, LINUX_MCP_KNOWN_HOSTS_PATH, LINUX_MCP_ALLOWED_LOG_PATHS, LINUX_MCP_LOG_DIR, LINUX_MCP_LOG_LEVEL, LINUX_MCP_LOG_RETENTION_DAYS

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "linux": {
      "command": "uvx",
      "args": [
        "linux-mcp-server"
      ],
      "env": {
        "LINUX_MCP_USER": "your-value",
        "LINUX_MCP_SSH_KEY_PATH": "your-value",
        "LINUX_MCP_KEY_PASSPHRASE": "your-value",
        "LINUX_MCP_SEARCH_FOR_SSH_KEY": "your-value",
        "LINUX_MCP_COMMAND_TIMEOUT": "your-value",
        "LINUX_MCP_VERIFY_HOST_KEYS": "your-value",
        "LINUX_MCP_KNOWN_HOSTS_PATH": "your-value",
        "LINUX_MCP_ALLOWED_LOG_PATHS": "your-value",
        "LINUX_MCP_LOG_DIR": "your-value",
        "LINUX_MCP_LOG_LEVEL": "your-value",
        "LINUX_MCP_LOG_RETENTION_DAYS": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add linux --env LINUX_MCP_USER=your-value --env LINUX_MCP_SSH_KEY_PATH=your-value --env LINUX_MCP_KEY_PASSPHRASE=your-value --env LINUX_MCP_SEARCH_FOR_SSH_KEY=your-value --env LINUX_MCP_COMMAND_TIMEOUT=your-value --env LINUX_MCP_VERIFY_HOST_KEYS=your-value --env LINUX_MCP_KNOWN_HOSTS_PATH=your-value --env LINUX_MCP_ALLOWED_LOG_PATHS=your-value --env LINUX_MCP_LOG_DIR=your-value --env LINUX_MCP_LOG_LEVEL=your-value --env LINUX_MCP_LOG_RETENTION_DAYS=your-value -- uvx linux-mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "linux": {
      "command": "uvx",
      "args": [
        "linux-mcp-server"
      ],
      "env": {
        "LINUX_MCP_USER": "your-value",
        "LINUX_MCP_SSH_KEY_PATH": "your-value",
        "LINUX_MCP_KEY_PASSPHRASE": "your-value",
        "LINUX_MCP_SEARCH_FOR_SSH_KEY": "your-value",
        "LINUX_MCP_COMMAND_TIMEOUT": "your-value",
        "LINUX_MCP_VERIFY_HOST_KEYS": "your-value",
        "LINUX_MCP_KNOWN_HOSTS_PATH": "your-value",
        "LINUX_MCP_ALLOWED_LOG_PATHS": "your-value",
        "LINUX_MCP_LOG_DIR": "your-value",
        "LINUX_MCP_LOG_LEVEL": "your-value",
        "LINUX_MCP_LOG_RETENTION_DAYS": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "linux": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "linux-mcp-server"
      ],
      "env": {
        "LINUX_MCP_USER": "your-value",
        "LINUX_MCP_SSH_KEY_PATH": "your-value",
        "LINUX_MCP_KEY_PASSPHRASE": "your-value",
        "LINUX_MCP_SEARCH_FOR_SSH_KEY": "your-value",
        "LINUX_MCP_COMMAND_TIMEOUT": "your-value",
        "LINUX_MCP_VERIFY_HOST_KEYS": "your-value",
        "LINUX_MCP_KNOWN_HOSTS_PATH": "your-value",
        "LINUX_MCP_ALLOWED_LOG_PATHS": "your-value",
        "LINUX_MCP_LOG_DIR": "your-value",
        "LINUX_MCP_LOG_LEVEL": "your-value",
        "LINUX_MCP_LOG_RETENTION_DAYS": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions

Is Linux MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: LINUX_MCP_KEY_PASSPHRASE

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.4.0) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?
