DeepL MCP Server
By thumbsupordown
DeepL's official MCP server exposes its translation engine to AI agents, covering text translation, whole-document translation, rephrasing, and lookups against glossaries and style rules — so an agent can apply the terminology and tone a team has already configured in DeepL rather than translating generically. It is open source under the MIT license, needs Node 18 or newer and a DeepL API key created from a DeepL account, and installs through npx or npm.
