Document Generator MCP Server

MCP (Model Context Protocol) server for creating DOCX and PDF documents with support for both STDIO and HTTP transports.

⚡ Quick Start with uv

# Clone the repository
git clone <repository-url>
cd docx_mcp

# Install uv if you haven't already
pip install uv

# Setup environment and install dependencies
uv venv
uv pip install -e .

# Run the server
uv run python main.py

🚀 Features

• Create DOCX documents - Full support for paragraphs, tables, and styling
• Create PDF documents - Generate PDFs with text and tables
• Session management - Build documents incrementally
• Multiple transports - STDIO for local CLI, HTTP for network access
• Clean architecture - Separated domain, infrastructure, and presentation layers
• Base64 support - Return documents as base64 for small files
• MCP Resources - Access generated documents via URIs

📦 Installation

Using pip

# Install dependencies
pip install -r requirements.txt

# Or using pyproject.toml
pip install -e .

Using uv (recommended)

# Install dependencies with uv
uv pip install -r requirements.txt

# Or install as editable package
uv pip install -e .

# Create virtual environment with uv
uv venv

🎯 Usage

STDIO Mode (Default)

For local CLI tools and desktop applications:

# Using python directly
python main.py

# Using uv
uv run python main.py

HTTP Mode

For network access and multiple clients:

# Using python directly
python main.py --transport http --host 0.0.0.0 --port 8000

# Using uv
uv run python main.py --transport http --host 0.0.0.0 --port 8000

Using FastMCP CLI

# STDIO mode
fastmcp run presentation/server.py:mcp
# Or with uv
uv run fastmcp run presentation/server.py:mcp

# HTTP mode
fastmcp run presentation/server.py:mcp --transport http --port 8000
# Or with uv
uv run fastmcp run presentation/server.py:mcp --transport http --port 8000

📋 MCP Resources

Documents can be accessed via MCP Resources:

• documents://{filename} - Get document content by filename
• documents://list - List all generated documents

🔄 Transport Modes

STDIO Transport

• Communication via standard input/output
• Each client spawns a new server process
• Ideal for CLI tools and desktop apps

HTTP Transport

• Web server on specified port
• Supports multiple concurrent clients
• Full bidirectional communication
• URL: http://host:port/mcp

⚙️ MCP Client Configuration

Claude Desktop Configuration

Windows

Add to your Claude Desktop config file (%APPDATA%\Claude\claude_desktop_config.json):

macOS/Linux

Add to your Claude Desktop config file (~/.claude/claude_desktop_config.json):

{
  "mcpServers": {
    "documents-work": {
      "command": "uv",
      "args": ["run", "python", "C:/Users/batashev/Desktop/MyProjects/docx_mcp/main.py"],
      "env": {}
    }
  }
}

Alternative configurations:

Using relative path:

{
  "mcpServers": {
    "documents-work": {
      "command": "uv",
      "args": ["run", "python", "main.py"],
      "cwd": "C:/Users/batashev/Desktop/MyProjects/docx_mcp"
    }
  }
}

Using pip instead of uv:

{
  "mcpServers": {
    "documents-work": {
      "command": "python",
      "args": ["C:/Users/batashev/Desktop/MyProjects/docx_mcp/main.py"]
    }
  }
}

With custom output directory:

{
  "mcpServers": {
    "documents-work": {
      "command": "uv",
      "args": ["run", "python", "main.py"],
      "cwd": "C:/Users/batashev/Desktop/MyProjects/docx_mcp",
      "env": {
        "OUTPUT_DIR": "C:/Users/batashev/Documents/generated_docs"
      }
    }
  }
}

📝 Examples

Create a simple DOCX

# Using MCP client
result = await client.call_tool("create_docx", {
    "title": "Hello World",
    "paragraphs": ["This is a test document"],
    "return_base64": true
})

Build document incrementally

# Create session
session = await client.call_tool("create_document_session", {
    "title": "Report"
})

# Add content
await client.call_tool("add_paragraph", {
    "document_id": session["document_id"],
    "text": "Introduction",
    "style": "bold"
})

# Save as PDF
result = await client.call_tool("save_document", {
    "document_id": session["document_id"],
    "format": "pdf"
})

🧪 Testing

# Test STDIO mode
python main.py
# Or with uv
uv run python main.py

# Test HTTP mode
python main.py --transport http --port 8000
# Or with uv
uv run python main.py --transport http --port 8000

# Run examples
python examples.py
# Or with uv
uv run python examples.py

# In another terminal, use curl or MCP client to test
curl -X POST http://localhost:8000/mcp \
  -H "Content-Type: application/json" \
  -d '{"method": "tools/list"}'
