On the MCP Server page, open the ChatGPT tab. ChatGPT connects through Connectors, so it requires a paid ChatGPT plan: the free plan doesn't support this feature. Generate a token on the page, go to Settings and Connectors in ChatGPT, add a new connector named Ads Editor, enter the URL shown and paste the token in the authorization field, using the format Bearer followed by your token. After that, ChatGPT can use Ads Editor's tools whenever you ask for something related to your campaigns.
