What the code does

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

    childProcess = spawn('node', [__filename, ...processArgs], {

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 proc = spawn(command, args, { shell: true });

          const filePath = path.join(this.options.workingDir, file);

        const ret = new Function(getStringFromWasm0(arg0, arg1));

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.
