deepl-mcp-server
A Model Context Protocol (MCP) server that provides translation capabilities using the DeepL API.
Features
- Translate text between numerous languages
- Rephrase text using DeepL's capabilities
- Access to all DeepL API languages and features
- Automatic language detection
- Formality control for supported languages
Installation
Installing via Smithery
To install deepl-mcp-server for Claude Desktop automatically via Smithery:
Clone this repository and install dependencies:
Configuration
DeepL API Key
You'll need a DeepL API key to use this server. You can get one by signing up at DeepL API. With a DeepL API Free account you can translate up to 500,000 characters/month for free.
Using with Claude Desktop
This MCP server integrates with Claude Desktop to provide translation capabilities directly in your conversations with Claude.
Configuration Steps
- Install Claude Desktop if you haven't already
- Create or edit the Claude Desktop configuration file:
- On macOS:
~/Library/Application Support/Claude/claude_desktop_config.json
- On Windows:
%AppData%\Claude\claude_desktop_config.json
- On Linux:
~/.config/Claude/claude_desktop_config.json
- On macOS:
- Add the DeepL MCP server configuration:
- Replace
/path/to/deepl-mcp-server
with an absolute path to your local copy of this repository - for example,/Users/robotwoman/Code/deepl-mcp-server
- Replace
your-api-key-here
with your actual DeepL API key - Restart Claude Desktop
Once configured, Claude will be able to use the DeepL translation tools when needed. You can ask Claude to translate text between languages, and it will use the DeepL API behind the scenes.
