DeepL Model Context Protocol (MCP) Server

The deepl-mcp-server package provides a Model Context Protocol (MCP) server that integrates DeepL's translation capabilities. It allows other applications, notably Claude Desktop, to leverage DeepL's API for features like text and document translation, rephrasing, automatic language detection, formality control, and glossary support. The current stable version is 1.1.0. This package is primarily designed as a standalone server or CLI tool, rather than a library for programmatic import. Its key differentiator is simplifying DeepL API access for MCP-compatible clients, particularly its direct configuration support for Claude Desktop, enabling AI assistants to perform high-quality translations. Release cadence is infrequent, focusing on stability and integration enhancements. It abstracts the complexities of the DeepL API, offering a streamlined interface via the MCP specification.
