What the code does

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.

    p = subprocess.Popen(

    def eval(self, code: str) -> Any:

  document.getElementById('presets').innerHTML = PRESETS.map((p,i) =>

    env = dict(os.environ)

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

          rustup toolchain install stable --target x86_64-unknown-linux-gnu --profile minimal --no-self-update
          rustup default stable
