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 keyPath = path.join(this.config.keysDir, keyName);

    const child = spawn(file, args, { cwd: options.cwd, env: options.env, stdio: ["ignore", "pipe", "pipe"] });

  if [ -S /var/run/docker.sock ]; then

const SECRET_FILES = new Set([".npmrc", ".yarnrc.yml", ".pypirc", ".netrc", ".git-credentials", ".pgpass", ".dockercfg"]);
