Connect

Five minutes and it's inside your AI.

You connect it once and it stays. If something goes sideways, the WhatsApp number is below and we sort it out.

Which one do you use?

Pick yours and I'll show you only those steps. If you use more than one, you can repeat afterwards.

See it all at once, without stepping through

  1. Open Customize

    It's in the sidebar on the left, under Artifacts. If your sidebar is collapsed, open it with the icon at the top.

    You can also get there from your profile, at the bottom, in Settings.

    In the left-hand column.

  2. Go to Connectors and press Add

    At the top you'll see three tabs: Skills, Connectors and Plugins. Choose Connectors.

    The Add button is the black one at the top right. It opens a window called “Add custom connector”.

    SkillsConnectorsPluginsAdd

  3. Fill in the two fields

    Copy them exactly as they are, including the https://.

    NameCerebro Ventas
    Remote MCP server URLhttps://cerebro.cofundo.io/mcp

    Agregar conector personalizado

    Cerebro Ventas

    Shown in the connector list.

    https://cerebro.cofundo.io/mcp

    The HTTPS address where the server accepts MCP requests.

    CancelContinue

  4. Don't touch anything else

    As soon as you paste the address, the window expands and two blocks appear: Authentication and OAuth Client.

    The right options are already selected — it says “Detected” in grey next to each one — so change nothing. Press Continue.

    Authentication

    Always required Detected

    Required when the server requests it

    None

    OAuth Client

    Use Anthropic-hosted client metadata

    No client ID — register one automatically Detected

    This is how it should look. Change nothing.

  5. Sign in with your email

    Claude will ask you to sign in. Use the same email you bought with.

    You'll get a six-digit code. Type it into the screen and that's it: it doesn't matter where you read the email, you can look at it on your phone and type it here.

    The email also has a link, if you'd rather click it. If you go that way, open it in this same browser.

  6. Authorise

    You'll see a screen saying “Claude wants to access your Brain”, with your email. Press Authorise.

    Claude wants to access your Brain

    you@email.com

    CancelAuthorize

  7. Try it with something of yours

    Not with an example question: with a real situation you have right now. For instance, “the client has gone quiet on me for two weeks”.

    It will come back with the technique, why it works, and the video from the trainer it came from.

In ChatGPT

  1. Turn on developer mode

    Without this the option to add anything doesn't appear, so it goes first.

    Click your name at the bottom left, go into Settings, then “Security and login”, and scroll down to Developer mode. Turn it on.

    Watch out for this. You'll see a red “elevated risk” warning. That's ChatGPT's standard warning for any connector OpenAI hasn't reviewed, and it shows for all of them. It's your call whether to turn it on.

    Developer mode

    Developer mode ELEVATED RISK

    Allows you to add unverified connectors…

    Turn it on
    In Settings → Security and login.

  2. Open Plugins

    It's in the left-hand column, and they're called plugins.

    At the top right there's a round button with a +. Press that.

  3. Fill in the form

    “New Plugin” opens. The icon and the description are optional: leave them blank.

    Under Connection leave Server URL selected, not Tunnel. And under Authentication, OAuth.

    NameCerebro Ventas
    Server URLhttps://cerebro.cofundo.io/mcp/chatgpt

    Watch out for this. Look at the /chatgpt on the end of the address. It's the part most often lost when copying and pasting, and without it nothing works.

    Authentication

    Look at the /chatgpt on the end. Without it, nothing works.

  4. Tick the warning box

    A red box appears at the bottom saying OpenAI hasn't reviewed this server. Tick “I understand and want to continue” and press Create.

    You don't need to touch “Advanced OAuth settings”: it's discovered automatically.

    ⚠ Custom MCP servers introduce risk.

    I understand and want to continue

    Create
    It shows for any connector OpenAI hasn't reviewed.

  5. Sign in with your email

    A blue screen appears saying “Add Cerebro Ventas to ChatGPT”. Press “Sign in with Cerebro Ventas” and use the same email you bought with.

    You'll get a six-digit code. Type it into the screen: you can read it on your phone and type it here, no problem.

  6. Check it and try it

    When it finishes, the plugin's page will show your email under Connection and the address under URL. That means it's in.

    Now tell it a real situation of yours, like “the client has gone quiet on me for two weeks”.

In Gemini, not quite yet

The Brain connects to Gemini through its CLI, which is a tool for developers. If you use it, there's nothing to configure: it discovers the connection on its own.

In the Gemini app — phone and web — you can't yet: Google only allows connectors like this one inside Spark, its agent layer, and not in normal chat. That's a limit of theirs, not of the Brain.

We're not putting a step-by-step here because we haven't done it end to end yet, and a tutorial for something nobody has done is making it up. The moment we connect it once, this page will say how.
