Envault MCP Server

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.

      await fs.writeFile(absoluteTarget, toSortedEnvFile(envMap), "utf-8");

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.

postinstall: node postinstall.mjs

  const absoluteTarget = path.join(cwd, targetFile);

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.

            execFileSync(terminalNotifierPath, args, { stdio: "ignore" });
