MCP server
DeepL
Translate text or whole documents through DeepL's engine, inside a Claude conversation.
Published by the company that makes the product.
What it can access
Sends the text you ask Claude to translate to DeepL's API using a DeepL account key you provide; no access to anything else on your machine.
Security note
Published by DeepL under an MIT licence, from DeepL's own GitHub organisation. Text sent through it is still subject to DeepL's free-versus-paid data policy, described in the DeepL tool catalogue entry. Use a paid DeepL key for anything sensitive, not the free tier.
Before you start
This one needs a terminal (a command-line window) and Node.js already on your computer. If a terminal is unfamiliar to you, install a Skill from this directory instead, or ask a technical colleague to do these steps with you.
To check whether Node.js is installed: open the Terminal app (PowerShell on Windows), type node -v, and press Enter. A version number means it is installed. “command not found” means you have to install it from its own official website first.
How to install
- Follow the “Installation” section of the project’s own instructions at github.com/DeepL/deepl-mcp-server.
- You will be asked to add a short block of text to Claude Desktop’s configuration file and restart the app.
- After restarting, open Claude Desktop’s Settings and confirm “DeepL MCP Server” is listed as connected.
How to remove it
- Open the configuration file from step 2, delete the block you added for “DeepL MCP Server”, save it, and restart Claude Desktop.
- Delete or revoke any API key or account you created for this on the vendor’s own website. Otherwise a stray copy of the configuration file is still a working key.
