How it works & safety

Understand where commands actually run, why the access address must be kept safe, and what the built-in safety gate blocks.

Before you lean on it, it’s worth two minutes to understand where your AI is and how it acts on your accounts. Once that clicks, you’ll know exactly what to keep safe.

Commands run on your own computer

PublishPort has three parts:

  • Desktop app (your computer): where publishing actually happens, using your machine’s browser and logged-in accounts.
  • Cloud relay: pure forwarding — it carries your AI’s instructions to your app, and never touches your platform passwords.
  • The AI (Claude Code, Codex, OpenClaw, Cursor, Manus, WorkBuddy, and others): sends the “what to post” instructions over the MCP address.

So content always goes out from your computer, with your accounts. Your data stays on your machine, and we never touch your platform passwords.

The access address is the key

Your AI can drive your computer because it holds the MCP address. The relay’s authentication is the only gate: whoever has the address can act through your machine. So:

  • Don’t paste it into public chats, screenshots, or repositories.
  • Only put it into AI clients you trust.
  • If you suspect it leaked, regenerate a new one in the app — the old address stops working immediately.

The built-in safety gate

Before a cloud AI runs anything on your machine, it passes a safety gate. Two protections are on by default:

  • Platform allowlist: by default your AI may only use officially supported platforms; anything off the list is refused. The “Allow platforms outside the list” toggle is off by default — turning it on carries risk, so leave it off unless you know what you’re doing.
  • Cleaner environment: in Settings you can further disable background telemetry, update prompts, and sign-in nudges to keep the runtime tidy.

About account risk

Everything happens on your own computer and accounts, so it behaves like your normal activity. But platform policies keep changing, and no tool can promise you’ll never be rate-limited or restricted. Run it at a human pace: don’t fire off high-frequency bulk posts or duplicate content, and follow each platform’s rules.
