Bring Machine Translation
to Google ADK
Learn how to connect DeepL to Google ADK and start using 14 AI agent tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code.
What is the DeepL MCP Server?
Connect your DeepL account to any AI agent and access neural machine translation through natural conversation.
What you can do
- Text Translation — Translate text into 30+ languages with optional formality control (formal, informal, or default)
- Glossary-Powered Translation — Apply custom glossaries to ensure consistent terminology across translations
- Glossary Management — Create, list, inspect, and delete custom glossaries with TSV term pairs
- Language Discovery — List all supported source and target languages, and glossary language pair combinations
- API Usage Monitoring — Track character count consumed, remaining quota, and billing period
- Document Translation — Monitor the progress of submitted document translations
How it works
1. Subscribe to this server
2. Enter your DeepL API Key from your account dashboard
3. Start translating from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Localization Teams — translate marketing copy, product descriptions, and documentation with consistent terminology via glossaries
- Content Creators — translate blog posts and social media content with appropriate formality for each market
- Developers — integrate high-quality translation into AI workflows and monitor API consumption

DeepL in Google ADK
DeepL and 3,400+ other MCP servers. One platform. One governance layer.
Teams that connect DeepL to Google ADK through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.
Raw MCP | Vinkius | |
|---|---|---|
| Server catalog | Find and host yourself | 3,400+ managed |
| Infrastructure | Self-hosted | Sandboxed V8 isolates |
| Credential handling | Plaintext in config | Vault + runtime injection |
| Data loss prevention | None | Configurable DLP policies |
| Kill switch | None | Global instant shutdown |
| Financial circuit breakers | None | Per-server limits + alerts |
| Audit trail | None | Ed25519 signed logs |
| SIEM log streaming | None | Splunk, Datadog, Webhook |
| Honeytokens | None | Canary alerts on leak |
| Custom domains | Not applicable | DNS challenge verified |
| GDPR compliance | Manual effort | Automated purge + export |
Why teams choose Vinkius for DeepL in Google ADK
The DeepL MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 14 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Google ADK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

How Vinkius secures
DeepL for Google ADK
Every tool call from Google ADK to the DeepL MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
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.
How does Google ADK connect to MCP servers?
Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.
Can ADK agents use multiple MCP servers?
Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.
Which Gemini models work best with MCP tools?
Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
