For AI assistants

Teach your AI to find the best game deals

Connect your AI assistant to GoCDKeys. Ask where a game is cheapest, whether to buy now or wait, or what just hit an all-time low.

You stay in control

Your privacy and security are always respected.

No account or login

Connect your assistant without creating a GoCDKeys account. Your assistant may need its own plan to add connectors.

Read-only access

Your assistant can only read game prices. It can't buy, pay or manage anything.

Disconnect anytime

Remove the connector from your assistant's settings and it's gone. There's nothing to cancel with us.

Connect my assistant

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

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.

2

Open Settings → Connectors in your assistant

Click your profile icon and look for it in the side menu.

3

Click Add custom connector and paste the address

Name it whatever you like — GoCDKeys works. The address goes in the server URL field.

More detail in the Claude documentation.

Connectors are only available on paid ChatGPT plans.

2

Open Settings → Connectors in your assistant

Click your profile icon and look for it in the side menu.

3

Click New connection and paste the address

Name it whatever you like — GoCDKeys works. The address goes in the server URL field.

Some features may vary under the platform's own policies. More detail in the ChatGPT documentation.

2

Open grok.com/connectors in your assistant

Click your profile icon and look for it in the side menu.

3

Name it whatever you like — GoCDKeys works. The address goes in the server URL field.

More detail in the Grok documentation.

2

Open ~/.gemini/settings.json on your machine

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

{
  "mcpServers": {
    "gocdkeys": {
      "httpUrl": "https://gocdkeys.com/agent/mcp"
    }
  }
}
3

Paste the server and restart Gemini CLI

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.

2

Open Search the settings for “connectors” in your assistant

Click your profile icon and look for it in the side menu.

3

Add a connector and paste the address

Name it whatever you like — GoCDKeys works. The address goes in the server URL field.

It works with any compatible assistant, and more of them recognise it every month.

4

Done — just ask

From now on your assistant answers price questions with our live data.

These platforms move their menus around often, and some limit what connectors can do under their own policies. If you can't find the option, search the settings for “connectors”.

Frequently asked questions

Do I need a GoCDKeys account?

No. Your assistant reads public price data, so there's no sign-up and no login with us.

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?

Not on our side: connecting is free and needs no key. Some assistants only allow connectors on their paid plans.

Which assistants work with it?

Claude and ChatGPT already use it. Any other assistant that lets you add a custom connector by its address can use the same one.

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.
