Send what ChatGPT makes as a private link.

Connect Stacktree to ChatGPT once. Every report, proposal or dashboard it writes then comes back as a private link your client can open, with a passcode or a link just for them, and no ChatGPT account on their side.

Can ChatGPT publish to Stacktree?

Yes. Stacktree connects to ChatGPT as a custom connector, using ChatGPT's developer mode on Plus, Pro, Business, Enterprise and Edu. You add the Stacktree server at https://api.stacktr.ee/mcp, sign in, and ChatGPT can publish what it writes to a private link on your account, set a passcode, make a link for one person and file the page under a client. Our ChatGPT store listing is in review; until it is approved, developer mode is how you connect.

Connect it in two minutes

  1. On chatgpt.com, open Settings, then Security and login, and turn on Developer mode.
  2. Open Plugins, select the plus button and create an app. Name it Stacktree, paste https://api.stacktr.ee/mcp as the server URL, and choose OAuth for authentication.
  3. Sign in to Stacktree (or create a free account) and approve the connection.
  4. In any chat, ask for a page and say where it goes: "Write a one-page kickoff summary for Harbour Kitchen and publish it privately on Stacktree with a passcode." ChatGPT asks you to confirm the first publish, then hands you the link.

On Business, Enterprise and Edu, your workspace admin may need to allow developer mode before step 1 appears.

What you can ask ChatGPT to do

  • Publish privately. The page gets an unguessable link that only people you send it to can find.
  • Add a passcode, or limit the page to a company email domain such as acme.com.
  • Make a link just for one person, so you can see when that person opened it.
  • File it under a client. Every page for one client collects in a client space with its own address.
  • Change it in place. Ask for edits and ChatGPT updates the same page, so the link you already sent still works.
  • Read your client's comments and fix the page they point at, then mark them resolved.

Why a link instead of a ChatGPT Site

ChatGPT can host what it makes as a ChatGPT Site. That suits public pages and full apps. For client work it has one catch: a private Site can be shared with named people outside your workspace, but each of them has to sign in to ChatGPT to open it. A Stacktree link opens in any browser, can carry a passcode or an end date, and sits with the rest of that client's work. That is the version to send to a client.

Where this stands

As of 5 October 2026, Stacktree's ChatGPT app is submitted and in review with OpenAI. When it is approved, connecting will be a couple of clicks from the Plugins directory, with no developer mode. If you connect now, nothing changes for you when it lands: same account, same pages, same links.

FAQ

Frequent questions

Which ChatGPT plans can connect Stacktree? +
Plus, Pro, Business, Enterprise and Edu. Custom connectors need ChatGPT's developer mode, which OpenAI offers on those plans and sets up on chatgpt.com. On Business, Enterprise and Edu, your workspace admin may need to allow it first.
Does it work in the ChatGPT desktop app? +
Yes. Add the connector once on chatgpt.com; it then shows up in the ChatGPT desktop app on the same account, in both Chat and Work.
Does my client need a ChatGPT account? +
No. The page opens in any browser. You can add a passcode, limit it to a company email domain, or make a link just for one person, and none of those ask the reader to sign up for anything.
How is this different from ChatGPT Sites? +
A ChatGPT Site is either public or limited to invited people, and since September 2026 those people can be outside your workspace, but each one has to sign in to ChatGPT to open it. A Stacktree link opens without an account, can carry a passcode or an expiry date, can be filed under a client, and tells you who opened it. Use Sites for public pages and full apps, and Stacktree for the private hand-off to a client.
Why does ChatGPT ask me to confirm before it publishes? +
Developer mode asks you to approve each action that changes something, such as publishing or setting a passcode. Choose Allow once to approve one action, or allow Stacktree for the conversation. When ChatGPT shows the passcode it is about to set, that is the page's passcode, not a password for any account.
When will Stacktree be in the ChatGPT store? +
Our ChatGPT app is submitted and in review with OpenAI. Once it is approved you can add it from the Plugins directory in a couple of clicks, without developer mode. Your pages, links and account stay exactly as they are.
How does the connection sign in? +
With OAuth. ChatGPT registers itself with Stacktree, you sign in and approve, and ChatGPT keeps the token. You can revoke it at any time from your Stacktree settings. The same server gives ChatGPT the twenty-eight Stacktree tools every other agent gets.
