This page is for admins of a ChatGPT **Business**, **Enterprise**, or **Edu** workspace. Custom connectors are off by default on these plans until an admin enables them.

If you're on ChatGPT Plus or Pro, you can install the Pleo MCP yourself without any admin step. See [How to Install the Pleo MCP in ChatGPT](/docs/current/pleo-mcp/how-tos/installation/chatgpt).

<RememberCallout title="Remember">
  Enabling Developer mode unlocks the option to create custom connectors. It doesn't install or authorise the Pleo MCP. A workspace admin still needs to publish and install it, and each member must authorise it themselves.
</RememberCallout>

## Steps

Follow the steps below to enable custom connectors for your workspace.

1. Go to **Workspace Settings → Permissions & Roles → Connected Data**.

2. Enable **Developer mode** (or the equivalent **custom MCP connectors** permission) for the workspace, or for specific roles if you want to limit who can create connectors.

<NoteCallout title="Don't see Developer mode?">
  This setting has rolled out gradually. If you don't see it under Connected Data, check under **Connectors → Draft** or contact OpenAI support to confirm availability for your workspace.
</NoteCallout>

3. Under **Admin → Apps**, review app permissions. Set the workspace default and any per-app overrides you need for the Pleo MCP once it's installed.

Custom connectors are now enabled for your workspace.
