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.
async exec(command: string[]): Promise<CommandResult> {
USER root
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
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 unlocalhost -- npx -y @unlocalhost/unlocalhost
{
"mcpServers": {
"unlocalhost": {
"args": [
"-y",
"@unlocalhost/unlocalhost"
],
"command": "npx"
}
}

command = "npx"
args = ["-y", "@unlocalhost/unlocalhost"]

This one needs environment variables set before it will start:
UNLOCALHOST_URL (Base URL of the unlocalhost instance to talk to. Defaults to the hosted instance. Set this to point the tools at your own self hosted deployment.), UNLOCALHOST_TOKEN (API token. Normally written by the unlocalhost_login tool after you approve the device in a browser, so you should not need to set this by hand.).
The author declared them in the registry entry; get the values from the project itself.
Deploy a site to its SFTP/FTP host from a coding agent. Changed files only, undo, live checks.
List, create and deploy your Prefab project templates from any MCP agent.
Deploy and manage Bult apps from AI coding agents.
Build, backtest, and deploy quantitative trading strategies from your AI agent.
Deploy the small apps your agent builds: one tool call returns a live, private shareable HTTPS link.
Deploy from your terminal, and give an AI coding agent the same abilities over MCP.
List, read, edit, and deploy your GenMB AI-generated apps from any MCP client.
Deploy a local folder, git repo, or Docker image to a live HTTPS URL from your AI chat.
