Connect DeepL to ChatGPT via an app
Depending on your ChatGPT plan, an admin or owner must add an app in developer mode to your ChatGPT instance by following these instructions before users can select the app to connect. If you cannot add a ChatGPT app yourself and don’t see a DeepL app in the list, reach out to your ChatGPT admin or owner within your organization.
To add an app in developer mode, do the following:
- Go to chatgpt.com or ChatGPT Desktop
- Enable the developer mode. Depending on your ChatGPT plan, different steps are necessary.
- Create an app
-
Enter a name for the app and select the OAuth authentication method. Then add the following URL:
https://mcp.deepl.com/v1/mcp
- Confirm that you trust the application, then click Create
- Test and publish the app for your users
To connect to DeepL via the app, do the following:
- Go to chatgpt.com or ChatGPT Desktop and start a chat
- Prompt the DeepL app to be used, then connect the app.
The DeepL login page will open so you can authenticate the app.
Connect DeepL to ChatGPT for developers
If you have an API subscription and you work with developer tools, such as Codex, you can connect to DeepL using the API key with this URL:
https://mcp-api.deepl.com/v1/mcp
Authentication is done with a DeepL API key sent in the Authorization header Authorization: DeepL-Auth-Key <YOUR_API_KEY>. Replace <YOUR_API_KEY> with you API key. For more information about API keys, see this article.
