What the code does

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

            proc = subprocess.Popen(

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

    if os.path.exists("/.dockerenv"):

            proc = subprocess.Popen(

            filepath = os.path.join(
                self._export_dir, f"ledger_{user_id}_{ts}.csv"
            )

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

claude mcp add dlbrowser -- uvx dlbrowser

{
  "mcpServers": {
    "dlbrowser": {
      "args": [
        "dlbrowser"
      ],
      "command": "uvx"
    }
  }
}

[mcp_servers.dlbrowser]
command = "uvx"
args = ["dlbrowser"]

{
  "mcpServers": {
    "dlbrowser": {
      "args": [
        "dlbrowser"
      ],
      "command": "uvx"
    }
  }
}

{
  "mcpServers": {
    "dlbrowser": {
      "args": [

      "command": "uvx"
    }
  }
}

This one needs environment variables set before it will start: DLBROWSER_API_KEY (API key for the hosted gateway. Optional — DLBrowser runs fully local without it.). The author declared them in the registry entry; get the values from the project itself.
