Frugal MCP Server

What the code does

We read the source, 10 min ago · rules 3dff92dd89df

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.

  const res = spawnSync(binPath, process.argv.slice(2), { stdio: "inherit" });

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.

        return filepath.Join(home, "Library", "Application Support", appDir, "storage")

    result = subprocess.run(cmd, env=env)

    env = dict(os.environ)
