## Capabilities

### Translate text with specific tones
Your agent translates plain text using standard, formal, or informal business language based on the intended audience.

### Preserve web structure during translation
The agent translates full HTML documents while safely keeping all tags and structural markup intact.

### Manage brand terminology consistency
You list available glossaries and query specific term mappings to enforce consistent branding across languages.

### Audit language support and usage
The agent lists all supported source or target languages, and provides real-time metrics on your character count and API limits.

## Use Cases

### Translating a complex corporate website
A Content Writer needs to update the German site. Instead of manually copy-pasting sections into an online tool, they ask their agent to use `translate_html_markup` to translate the whole page structure while keeping all formatting intact.

### Ensuring legal document consistency
A Localization Manager is working on a new product guide. They instruct their agent to reference the company glossary via `get_account_glossaries` before translating any text, guaranteeing that legal terms are never mistranslated.

### Drafting social media campaign copy
An Operations Lead needs a quick batch of translated posts. They ask their agent to use `translate_text_informal` for the target language, ensuring the tone matches casual platform expectations.

### Setting up multilingual AI workflows
A developer integrates DeepL into an automated pipeline. The first step is calling `get_target_languages` to build a complete dropdown menu of all possible destination languages for the client.

## Benefits

- Enforce brand consistency across all languages. Use the `get_account_glossaries` and `get_glossary_dictionary` tools to ensure specific terminology is always correct.
- Maintain high fidelity in complex layouts. The `translate_html_markup` tool translates web pages while guaranteeing that tags like `<b>` or `<p>` remain intact.
- Control your budget and scope. Check your usage with `get_api_usage`, so you never hit an unexpected character limit mid-project.
- Match the required communication style. You can dictate tone using tools like `translate_text_formal` for boardroom reports or `translate_text_informal` for social media posts.
- Plan your global rollout accurately. Before starting, use `get_source_languages` and `get_target_languages` to confirm full language coverage.

## How It Works

The bottom line is, you write the instruction to your agent once, and it handles all the complex API calls—translation, auditing, and resource management—for you.

1. Subscribe to this MCP and enter your DeepL API key (Free or Pro).
2. Your AI client connects the credentials, making translation services immediately available.
3. You prompt your agent with text, a required tone, and target languages. Your agent executes the translation, checks usage metrics, and handles any necessary glossary lookups.

## Frequently Asked Questions

**How does the DeepL MCP handle specialized brand terms during translation?**
It maintains consistency by allowing your agent to reference specific glossaries. You can list and query these glossaries, ensuring that product names or legal phrases are translated exactly as needed every single time.

**Can DeepL translate web pages while keeping the formatting correct?**
Yes. The MCP uses a specific tool to translate full HTML documents. This process translates the content but guarantees that all structural elements, like bolding or table layouts, remain exactly where they should be.

**What if I need different tones for different parts of my copy?**
You don't have to use one tone everywhere. You can direct your agent to translate the opening email using a formal tone and then switch it to an informal tone when writing the follow-up social media post.

**Is DeepL good for large-scale localization projects?**
Absolutely. It helps you manage scale by allowing your agent to check your API usage limits before starting a job, preventing unexpected failures on massive content batches.

**Does DeepL support translating text into languages I haven't used before?**
The MCP lets your agent list every supported target language. You can audit the full list of available options to confirm that any required language is ready for translation.
