Connecting the Talkpush MCP to ChatGPT requires Developer Mode, which is available on Plus, Pro, Business, Enterprise, and Edu plans. As an individual, you'll create a custom app and authenticate with your own credentials. As a workspace admin, you'll go through the same creation flow but publish the app so all members can access it.

ChatGPT
As an individual user (Plus / Pro)
Custom MCP apps require Developer Mode, available to Plus, Pro, Business, Enterprise, and Edu users.
Open ChatGPT → Settings
Navigate to Apps → Advanced settings.
Toggle Developer Mode to ON and accept the warning ("Allows you to add unverified connectors that could modify or erase data permanently").
Click Create App
Fill in name, description, MCP server URL.
Under Registration Method, choose User-Defined OAuth Client.
Enter the OAuth Client ID (this will be provided on the MCP website)
Confirm "I understand and want to continue" and click Create.
You'll be directed to the MCP site, enter your Client ID and Secret.
In a chat, open the Connected apps / + menu and toggle your connector on. When Developer Mode is active, the input box gets an orange border and chat memory is automatically disabled to prevent leaks.
As a workspace admin
The process to add the connector as a workspace administrator is similar, except you must publish the app for workspace use.
Publishing a custom app to the workspace:
As an authorized developer, enter your Workspace Settings.
Under Apps, choose Create. You'll be prompted to enable Developer mode if not enabled yet.
Follow the same steps for setup described above.
Once created, it is submitted for review as a draft.
An admin/owner (it can be yourself) approves and publishes it to the workspace.
All users may start accessing the Talkpush app once connected.
