BookBridge

GitHub PyPI Python Poetry FastMCP uv License: MIT

🎉 Now available on PyPI! Install with one simple command:

uvx bookbridge-mcp

Or run directly from GitHub:

uvx --from git+https://github.com/Polly2014/BookBridge-MCP-Server bookbridge-mcp

A powerful Model Context Protocol (MCP) server for Chinese-to-English book translation and document processing, built with FastMCP framework.

🌉 Overview

BookBridge-MCP provides a comprehensive solution for translating Chinese books and documents to English while preserving formatting and structure. The server follows a client-side LLM architecture, where the MCP server handles document processing and provides translation resources, while LLM interactions are performed on the client side.

---

🚀 Detailed Installation

1. Prerequisites

• Python 3.10 or higher
• Poetry (recommended) or pip

2. Installation

Option A: Using Poetry (Recommended)

git clone https://github.com/your-repo/BookBridge-MCP.git
cd BookBridge-MCP

# Automated setup (installs Poetry if needed)
python setup_poetry.py

# Or manual setup if Poetry is already installed
poetry install --with dev --with client

Option B: Using pip

git clone https://github.com/your-repo/BookBridge-MCP.git
cd BookBridge-MCP
pip install -r requirements.txt

3. Start the MCP Server

Using Poetry:

poetry run python start.py
# or
poetry run bookbridge-server
# or using make commands
make run              # Unix/Linux/Mac
make.bat run          # Windows

Using pip:

python start.py

The server will start and listen for MCP connections on the configured port.

3. Client-Side Integration

The MCP server provides tools, resources, and prompts. Your client application handles the LLM interactions:

from examples.client_example import BookBridgeClient

# Initialize client with your OpenAI API key
client = BookBridgeClient(api_key="your_openai_api_key")

# Translate a document
result = await client.translate_document(
    file_path="./my_chinese_book.docx",
    content_type="academic"  # or "general", "technical", "creative"
)

# Save the translation
output_path = await client.save_translation(
    result, 
    "./output/translated_book.md"
)

🔧 Configuration

MCP Client Configuration

You can configure your MCP client in three ways:

Option 1: Using uvx with GitHub (Recommended)

Edit your mcp.json file:

{
  "servers": {
    "Book-Bridge-MCP": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/Polly2014/BookBridge-MCP-Server",
        "bookbridge-server"
      ],
      "type": "stdio"
    }
  }
}

Advantages:

• ✅ No local installation required
• ✅ Always runs the latest version from GitHub
• ✅ Automatic dependency management via uv
• ✅ Clean and simple configuration

Option 2: Using Local Installation

{
  "servers": {
    "Book-Bridge-MCP": {
      "command": "python",
      "args": [
        "D:\\path\\to\\BookBridge-MCP\\server.py"
      ],
      "cwd": "D:\\path\\to\\BookBridge-MCP",
      "type": "stdio"
    }
  }
}

Option 3: Using npx-like syntax (if published to PyPI)

{
  "servers": {
    "Book-Bridge-MCP": {
      "command": "uvx",
      "args": ["bookbridge-mcp"],
      "type": "stdio"
    }
  }
}

Server Configuration

Edit config.env to customize settings:

# Document Processing Settings
INPUT_DIR=./input_documents
OUTPUT_DIR=./output_documents
TEMP_DIR=./temp_documents

# Translation Settings (for client reference)
SOURCE_LANGUAGE=chinese
TARGET_LANGUAGE=english

# MCP Server Settings
SERVER_NAME=BookBridge-MCP
SERVER_VERSION=1.0.0

�️ Development Workflow

Using Poetry (Recommended)

Poetry provides better dependency management and development workflow:

# Complete development setup
poetry install --with dev --with client
poetry run pre-commit install

# Development commands using Poetry
poetry run python start.py          # Start server
poetry run pytest                   # Run tests  
poetry run pytest --cov=src         # Tests with coverage
poetry run black .                  # Format code
poetry run isort .                  # Sort imports
poetry run flake8 src/              # Lint code
poetry run mypy src/                # Type checking

Using Make Commands

For convenience, use the provided Makefile (Unix/Linux/Mac) or make.bat (Windows):

# Unix/Linux/Mac
make dev-setup      # Complete development setup
make run            # Start server
make test           # Run tests
make format         # Format code
make lint           # Lint code
make type-check     # Type checking
make check          # Run all checks
make clean          # Clean temporary files

# Windows
make.bat dev-setup  # Complete development setup
make.bat run        # Start server
make.bat test       # Run tests
make.bat format     # Format code
make.bat lint       # Lint code
make.bat type-check # Type checking
make.bat check      # Run all checks
make.bat clean      # Clean temporary files

Package Management

# Add new dependency
poetry add package_name

# Add development dependency
poetry add --group dev package_name

# Add client dependency (optional for client usage)
poetry add --group client package_name

# Update dependencies
poetry update

# Show installed packages
poetry show

# Environment information
poetry env info

�💡 Usage Examples

Basic Document Translation

# Process and translate a Word document
result = await client.translate_document(
    file_path="./books/chinese_novel.docx",
    content_type="creative"
)

print(f"Translated {result['summary']['original_words']} words")
print(f"Used {result['summary']['token_usage']} tokens")

Batch Processing

# Process multiple documents
documents = ["doc1.docx", "doc2.md", "doc3.docx"]

for doc in documents:
    result = await client.translate_document(doc, "academic")
    await client.save_translation(result, f"./output/{doc}_translated.md")

Custom Content Types

You can request specific translation prompts from the server:

# Get specialized prompt for technical content
prompt = await client.get_translation_prompt("technical")

# Use prompt for custom translation
translation = await client.translate_content(
    content="技术文档内容...",
    content_type="technical"
)

🎯 Client-Side LLM Benefits

1. Flexibility: Clients can use any LLM provider or model
2. Security: API keys stay on the client side
3. Scalability: Server focuses on document processing
4. Customization: Clients can customize translation parameters
5. Cost Control: Clients manage their own LLM usage

📊 Translation Quality Features

• Smart Chunking: Preserve document structure when splitting large texts
• Format Preservation: Maintain headers, lists, and emphasis
• Metrics Calculation: Analyze translation quality and completeness
• Content-Type Optimization: Specialized prompts for different text types
