MCP server for PDF translation using [pdf2zh-next](https://github.com/funstory-ai/BabelDOC) as the PDF processing backend. Designed for **Claude Desktop**.

Instead of translating each segment independently (which loses context), this server extracts all segments at once and lets the LLM translate them together — preserving terminology consistency and context across the entire document.

> **Using Claude Code?** Check out [pdf2zh-next-skill](https://github.com/JaeHyeon-KAIST/pdf2zh-next-skill) — a lightweight skill-based approach without MCP overhead. It handles large PDFs better by leveraging Claude Code's direct file I/O and auto-continuation.

## How it works

```
┌─────────────────────────────────────────────────┐
│  Claude Desktop                                  │
│                                                  │
│  1. extract_segments  ──→  segments + formulas   │
│  2. LLM translates all segments at once          │
│  3. assemble_translated  ──→  final PDF          │
└─────────────────────────────────────────────────┘
```

The LLM sees every segment before translating — so terminology stays consistent, cross-page sentences flow naturally, and formula placeholders are preserved correctly.

## Prerequisites

[pdf2zh-next](https://github.com/funstory-ai/BabelDOC) must be installed separately:

```bash
uv tool install pdf2zh-next
```

Verify installation:

```bash
pdf2zh_next --version
```

> You need [uv](https://docs.astral.sh/uv/) to install both pdf2zh-next and this server.
