The DeepL MCP server gives any compatible assistant access to DeepL translation, writing, and glossaries, no custom integration needed. Which AI assistants does DeepL work with? Claude, ChatGPT, Microsoft Copilot, and developer tools like Cursor and Continue. Any client that supports remote MCP servers can connect to DeepL. Which DeepL subscription works with AI agents? Any seat-based plan with a DeepL account works, including DeepL Free. Whether you're on a free account, a seat-based plan (Individual, Team, or Business), or DeepL for Enterprise, you simply sign in with your DeepL account when your AI tool asks—no API key needed. Does this work with our corporate single sign-on (SSO)? You connect by signing in once with your DeepL account. If your organization uses single sign-on (SSO) with DeepL, that login goes through your identity provider as usual, with no separate credentials to manage. Administrators control which users can connect at the organization level. How is usage billed? When you sign in with your DeepL account, MCP usage is included in your subscription and works within its fair-usage limits; there is no separate bill. The connector itself is free. Is my data secure? Yes. Requests are processed under your existing DeepL agreement, and your texts are never used to train models. Administrators can enable or disable agent access for the whole organization. Connect DeepL to your agent
