real example · GoCDKeys
Where can I get Hollow Knight Silksong cheapest for PC?

The cheapest right now is 12.35 EUR at Eneba Steam Key.

Is it worth buying now, or should I wait?

I'd go for it. As Steam Key it normally sits at 23.59 EUR, and right now it is well below that.

In the 689 days we've been tracking it, it has only been this cheap or cheaper on 8 of them.

Its all-time low as Steam Key was 5.80 EUR.

Can you send me the link?

Here you go, with every deal compared.

You stay in control

No account, no login

You connect nothing of your own. Your assistant only reads public price data, the same data you see on the site.

Read-only

It can look up prices and history. It can't buy, pay or manage anything on your behalf.

Disconnect whenever you like

Remove the connector from your assistant and that's that. There's nothing to cancel.

The purchase is always yours

Your assistant hands you the link to the deal. You finish the purchase at the store, the same as always.

One minute to set up

Unlike other connectors, there's nothing to switch on in any account: just add the server address to your assistant.

  1. 1

    Copy the address

    It's the only thing you need.

    The address you need to copy https://gocdkeys.com/agent/mcp

Steps 2 and 3 change with the assistant you pick above.

Connectors are only available on paid ChatGPT plans.

    If it does not exist, create it. For a single project .gemini/settings.json works too.

    The name inside (gocdkeys) is what you will see when you call it.

    Gemini connects through Gemini CLI, the API and Gemini Enterprise. The Gemini app cannot add custom connectors yet: when it can, the address will be the same. More detail in the Gemini CLI.

Frequently asked questions

Do I need a GoCDKeys account?

No. The connector reads public price data. There's no sign-up and no login.

Can my assistant buy things for me?

No. It only looks up prices and history. You make the purchase yourself, at the store, through the link it gives you.

Does it cost anything?

No. Connecting it is free and it needs no key.

Which assistants work with it?

Claude, ChatGPT, Grok and any other assistant that supports connectors. The list grows every month.

Can I trust the prices the AI gives me?

The assistant answers with our live data and a timestamp on it. Even so, check the price on the game page before you buy: it moves every few hours.
