# Connect ChatGPT

> Step by step to connect ChatGPT to your Memberfy community through developer mode, create the connector, authorize with your account, use it in a conversation, and what's different from Claude.

In ChatGPT, third-party MCP servers come in through **developer mode**. You turn the mode on, create a connector with the Memberfy address, authorize with your account, and the connector shows up in your conversations.

> [!TIP]
> The address and these steps are also in Memberfy itself. In **My Account › AI assistants** (`/account?tab=assistants`), or in **Settings › AI assistants** (owner and admin), the **Connect an assistant** block shows the **MCP server address** with a **Copy** button, and the steps for each assistant: **Claude**, **ChatGPT** and **Claude Code / Cursor** (with the command and the file snippet, under **Copy the snippet**).

## Before you start

- A ChatGPT account on a plan that offers developer mode. In company accounts, the ChatGPT workspace admin may need to enable it.
- A Memberfy account, with a role in the community you want to connect.
- The server address: **`https://api.memberfy.net/mcp`**.

## Step by step

1. In ChatGPT, open **Settings** (in the menu under your name).
2. Go to **Apps & Connectors** and open **Advanced settings**.
3. Turn on **Developer mode**. ChatGPT warns that developer connectors aren't verified by it: that's the case for any MCP server outside the official list.
4. Go back to **Apps & Connectors** and click **Create**.
5. Fill in:
   - **Name**: *Memberfy*;
   - **Description**: for example, *Runs my Memberfy community*;
   - **MCP Server URL**: `https://api.memberfy.net/mcp`;
   - **Authentication**: **OAuth**.
6. Confirm that you trust the application and click **Create**.
7. ChatGPT opens the Memberfy window. If asked, sign in with your email and password.
8. On the authorization screen, choose the **community**, check what ChatGPT will be able to do and click **Allow**. See [what the screen shows](/mcp/autorizar-e-desconectar#the-consent-screen).
9. Back in ChatGPT, the connector appears with its list of tools.

> [!TIP]
> ChatGPT renames these menus often. If you can't find them, search for "developer mode" in ChatGPT's help. The address and the authentication type (OAuth) don't change.

## Using it in a conversation

1. Start a new conversation.
2. In the **+** button of the message box, choose **Developer mode** and select the **Memberfy** connector.
3. Test it: *"Which Memberfy community are you connected to, and with what role?"*.

ChatGPT asks for your approval before tools that write; that approval is ChatGPT's own. On top of that, the Memberfy tools that [touch money or delete](/mcp/dinheiro-e-confirmacao) always return a summary first and only act after your yes, in two calls, which works in ChatGPT the same way as in Claude. Everything else runs on the first call.

## Ready-made recipes

In Claude, Memberfy offers eight ready-made recipes in a menu ([see which](/mcp/conectar-o-claude#ready-made-recipes-in-the-menu)). In ChatGPT, as of this article, the connector uses Memberfy's tools but doesn't show that menu: ask in your own words or copy the request from one of the [Recipes](/mcp/receitas). The result is the same.

> [!NOTE]
> **Connected ChatGPT before October 6, 2026?** The tools now have English names (`create_post` instead of `criar_post`). A conversation that was already open may keep the old list: open a **new conversation**. If the old names keep showing up, refresh the connector in **Settings › Apps & Connectors**.

## Two communities

Create a second connector with another name (*Memberfy · School*) and the same address, and choose the other community when authorizing. In the conversation, select only the connector for the community you're working in.

## Disconnecting

- **In ChatGPT**: in **Apps & Connectors**, open the connector and remove it.
- **In Memberfy**: **My Account › AI assistants** (`/account?tab=assistants`), **Disconnect**. It cuts access immediately. See [Authorize and disconnect](/mcp/autorizar-e-desconectar).

## Connection problems

| What happens | What to do |
|---|---|
| There's no **Create** option | Developer mode is off, or your plan doesn't offer it. Check **Advanced settings** |
| *"This access request isn't valid."* in the Memberfy window | Delete the connector and create it again |
| The connector appears, but with no tools | The authorization didn't finish. Open the connector and connect again |
| Tools are missing | Your role doesn't allow them. See [Tools](/mcp/ferramentas) |
