@questlang/mcp-server

MCP server for AI-powered translation of i18n/localization files. Works with Claude Code, Cursor, and VS Code.

Quick Start

npx -y @questlang/mcp-server init

This creates:

• .mcp.json — MCP server configuration for your IDE
• .claude/commands/translate.md — the /translate skill for Claude Code

Setup

1. Create an account at questlang.ru
2. Get an API key from API Keys
3. Set the key:

export QUESTLANG_API_KEY=ql_your_key_here

Or paste it into the QUESTLANG_API_KEY field in .mcp.json.

Usage

In Claude Code, use the /translate slash command:

/translate Spanish, French, Japanese

Or ask in natural language:

Scan my project for localization files and translate them to Spanish
