Team-wide localization via the DeepL MCP Server

This MCP Server lets your team run `translate_html_markup` inside VS Code Copilot to translate UI layouts without stripping out critical code attributes. Developers can check language compatibility instantly. The editor queries `get_target_languages` to see if a specific regional dialect is supported before committing new localization files to the shared repository.

Enforce dictionary standards across your workspace

This tool reads your central dictionaries by executing `get_account_glossaries` directly inside the VS Code Copilot chat interface. For deeper audits, the tool runs `get_glossary_dictionary` to display term mappings. Your team can verify how specific technical phrases are translated without leaving their active coding workspace.

Contextual tone adjustments for team workflows

The server calls `translate_text_formal` or `translate_text_informal` to match your product's voice perfectly within VS Code Copilot. Standard text is handled by `translate_text_standard`, giving your developers a reliable baseline. This automation keeps your internationalization files accurate and professional across every branch.

Setup guide

Set up DeepL MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the DeepL MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the DeepL tools listed. Try asking: "List my recent DeepL transactions" and Copilot will invoke them automatically.
