An MCP server that translates documents (PPTX, PDF, DOCX, XLSX) while preserving the original layout — including text embedded in images. Works with any LLM client that supports MCP.

一个 MCP 服务器，可翻译文档（PPTX、PDF、DOCX、XLSX），保持原始排版格式不变，并支持翻译图片中嵌入的文字。兼容所有支持 MCP 协议的 LLM 客户端。

## Features / 功能亮点

- **Any language pair** — Chinese ↔ English, French ↔ Japanese, or any combination the host LLM supports
- **No API key required** for text translation — uses whatever LLM is running in your client
- **Optional image translation** — set `GEMINI_API_KEY` to automatically translate text in screenshots, diagrams, and charts via Gemini
- **Format preservation** — fonts, colors, sizes, positioning all maintained; font size auto-scales for longer translations
- **Smart image filtering** — skips icons, logos, and duplicates to minimize API calls
- **Best with Claude** — tested and optimized for Claude; other LLMs may work but results vary
