Bring Machine Translation
to VS Code Copilot
Learn how to connect DeepL to VS Code Copilot 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

Why VS Code Copilot?
GitHub Copilot Agent mode brings DeepL data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 14 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
- —
VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor
- —
Project-scoped MCP configs (
.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access - —
Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop
- —
GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services
DeepL in VS Code Copilot
DeepL and 3,400+ other MCP servers. One platform. One governance layer.
Teams that connect DeepL to VS Code Copilot 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.

Why teams choose Vinkius for DeepL in VS Code Copilot
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 VS Code Copilot 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 VS Code Copilot
Every tool call from VS Code Copilot 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.
Which VS Code version supports MCP?
MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.
How do I switch to Agent mode?
Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.
Can I restrict which MCP tools Copilot can access?
Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.
Does MCP work in VS Code Remote or Codespaces?
Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
MCP tools not available
Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
