Connect DeepL to Microsoft Copilot by creating an agent

Prerequisites

• DeepL AI connectors are enabled for your team. Reach out to your team admin to enable DeepL usage in AI assistants or to create an agent in Microsoft Copilot. For more information, see this article. 
• A Microsoft Copilot Studio license
• Generative orchestration is enabled on your agent (default)
• Organization policies apply: MCP connections in Copilot Studio go through Power Platform connectors. Therefore, your organization’s data loss prevention (DLP) policies apply and may block the connection. Contact your Microsoft admin if you cannot add the connector.

Then, you can select the agent to connect. If you cannot add a custom agent and do not see a DeepL agent in the list, contact your Copilot admin. For more information, see this article.
