# DeepL MCP for AI Agents AI Agent Connect > DeepL MCP lets your AI client handle high-quality translations across dozens of languages. It supports formal and informal tones, preserves HTML structures, and lets you manage brand-specific glossaries. Use it to automate multilingual content without losing nuance or breaking your website's code. It's the fastest way to get professional-grade results for global marketing and localization. ## Overview - **Category:** productivity - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_5oECiqSmzlOUOddDschUcI8F03XBgMpmjUO0ibrW/ai-agent-connect - **Tags:** machine-translation, language-processing, glossary-management, document-translation, api-integration ## Description Imagine you're managing a global marketing campaign and need to turn a set of landing pages into five different languages. Usually, you'd have to copy-paste chunks of text into a translator, check if the tone sounds right for each region, and pray it doesn't mess up your HTML tags. With this DeepL MCP, your AI agent does that heavy lifting for you. You can tell your agent to translate a whole block of content while keeping it strictly professional or making it sound like a casual DM, depending on the audience. It even handles the technical side, like keeping your web code intact while swapping out the text. You can also pull in your existing brand glossaries so the agent knows exactly how to translate specific product names or company terms. It's a big part of how teams are scaling their content globally through the Vinkius catalog, turning a manual chore into a quick conversation with your agent. You get consistent, accurate translations that actually sound human, without ever having to log into a separate dashboard to check your character limits or manage your language pairs. ## Tools ### create_glossary Create a glossary ### delete_glossary Delete a glossary ### get_document_status Check document translation status ### get_glossary_entries Get glossary entries ### get_glossary Get glossary details ### get_usage Check API usage ### list_glossaries List glossaries ### list_glossary_language_pairs List glossary language pairs ### list_source_languages List source languages ### list_target_languages List target languages ### translate_formal Translate with formal tone ### translate_informal Translate with informal tone ### translate_text Translate text ### translate_with_glossary Translate using glossary ## Prompt Examples **Prompt:** ``` Translate 'Welcome to our platform' into German using a formal tone. ``` **Response:** ``` The formal German translation for 'Welcome to our platform' is: **Willkommen auf unserer Plattform.** I've detected the source language as English.

Ask your AI client to translate text or check your usage. ## Frequently Asked Questions **Can DeepL MCP handle my website's HTML?** Yes, it can. The tool specifically preserves your HTML tags and structure while only translating the text content inside them. **How do I keep my brand terms consistent?** You can use brand glossaries. The Connector lets your agent access your configured terms so it always uses the correct names for your products and company. **Does it support different tones for different platforms?** Yes, it does. You can choose between formal tones for business documents and informal tones for social media or casual messages. **Can I see my DeepL API limits through the agent?** Yes, you can check your current character count and remaining limits directly through your AI client to stay on budget. **Is DeepL MCP good for social media translations?** It's excellent for that because it has a specific mode for informal and casual tones, which helps your content sound more natural. **What languages can I translate into with DeepL MCP?** You can list all supported target languages through your agent to see the full range of options, which includes dozens of global languages. **How do I find my DeepL API Key?** Log in to your [**DeepL account**](https://www.deepl.com/pro-account/plan), and you will find your Authentication Key under the 'Account' tab. Copy and paste it below. **Does this work with both Free and Pro API keys?** Yes. This server automatically detects if you are using a Free key (ending in `:fx`) or a Pro key and routes requests to the correct endpoint. **Can the agent use glossaries?** Yes. You can list your existing glossaries via the `get_glossaries` tool and identify their IDs to maintain consistency in your agent-led translations. **Can I control the formality of translations (formal vs. informal)?** Yes! Use `translate_formal` for professional communications (e.g., contracts, official correspondence) or `translate_informal` for casual content (e.g., social media, chat). The standard `translate_text` tool also accepts an optional formality parameter ('more', 'less', or 'default'). Note: formality control is available for select target languages including DE, FR, ES, PT-BR, and others. **Can I create custom glossaries to ensure consistent terminology?** Yes. Use `create_glossary` with a name, source language, target language, and TSV entries (tab-separated source→target pairs). Then use `translate_with_glossary` to apply the glossary during translation. Use `list_glossaries` to see all glossaries, `get_glossary_entries` to inspect term pairs, and `list_glossary_language_pairs` for supported combinations. **How does DeepL authentication differ from standard Bearer tokens?** DeepL uses a custom Authorization header format: `DeepL-Auth-Key YOUR_KEY` (not Bearer). Your API key is generated from the DeepL account dashboard. Free accounts use `api-free.deepl.com`, while Pro accounts use `api.deepl.com`. Use `get_usage` to check your current character consumption and plan limits.
