What the code does

We read the source, 19 h ago · rules 3dff92dd89df

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.

          fs.writeFileSync(outFd, pdfBuffer);

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 fullPath = path.join(stagingDir, filename);

    const child = spawn(process.execPath, [script], {

  if (isUnder(resolvedAbs, sshDir)) return { hit: true, reason: '~/.ssh/** is sensitive' };

  <script src="https://appsforoffice.microsoft.com/lib/1.1/hosted/office.js"></script>

    const entries = fs.readdirSync(workspacePath, { withFileTypes: true });
