ChatGPT connects to custom MCP servers through **developer mode**. It's available on Plus, Pro, Business, Enterprise and Edu plans. On a workspace plan, an admin may need to allow it.

## Turn on developer mode

<Steps>

1. In ChatGPT, open **Settings**.

2. Find **Developer mode** and switch it on. Depending on your version it's under **Apps & Connectors → Advanced settings**, or under **Security and login**.

</Steps>

## Add GatherEasy

<Steps>

1. In **Settings**, open **Apps & Connectors** (called **Apps** or **Plugins** in some versions) and choose **Create** (or the **+** button).

2. Fill in:
   - **Name**: `GatherEasy`
   - **Description**: `Find events and venues, RSVP and manage my GatherEasy events`
   - **MCP server URL**: `https://gathereasy.rsvp/api/mcp`
   - **Authentication**: **OAuth**

3. Confirm that you trust the app and choose **Create**.

4. A GatherEasy window opens. Sign in and choose **Allow access**. See [Sign-in and permissions](https://help.gathereasy.rsvp/ai-assistants/permissions.md).

</Steps>

## Use it in a chat

Start a new chat, choose the **+** button in the message box and select **Developer mode** (or **More → GatherEasy**), then make sure GatherEasy is enabled for the conversation. Ask, for example: "Use GatherEasy to find a free event near me this Saturday."

ChatGPT asks you to confirm before GatherEasy creates, changes or sends anything. Read each confirmation before you approve it.

## When GatherEasy adds new features

ChatGPT keeps a copy of the app's tool list. After a GatherEasy update, open the app's settings in **Apps & Connectors** and choose **Refresh** to pick up new tools.

<Aside type="note">
  OpenAI changes these menus often. If something has moved, search ChatGPT's
  help for "developer mode" and "MCP".
