What the code does

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

  const result = spawnSync(binaryPath, process.argv.slice(2), {

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 result = spawnSync(binaryPath, process.argv.slice(2), {

      const candidate = path.join(pkgRoot, subpath);

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.

    if exists(Path::new("/.dockerenv")) {

SELECT
  blks_hit,
  blks_read,
  CASE WHEN blks_hit + blks_read = 0 THEN NULL

      el.innerHTML = notice(kind, html);
