DeepL Translator

Integrates with DeepL to provide high-quality text translation and rephrasing between numerous languages with formality controls for supported language pairs.

The DeepL MCP server provides AI assistants with direct access to DeepL's translation capabilities through a Node.js implementation. Developed by DeepL SE, this server exposes tools for translating text between numerous languages, rephrasing content with different writing styles and tones, and retrieving available language options. It leverages the Model Context Protocol SDK to establish a stdio-based communication channel, caches language lists for improved performance, and includes formality controls for supported languages. The implementation is particularly valuable for users who need high-quality translations or text rephrasing without switching contexts from their AI assistant conversation.
