## MCP Tools

This server provides the following tools:

### `convert_document`
Convert a document from one format to another.

**Arguments:**
- `source_path` (string, required): Path to the source document.
- `target_format` (string, required): Target format (`html`, `pdf`, `markdown`, `docx`, `text`).
- `output_path` (string, optional): Path for the output file.
- `source_format` (string, optional): Format of the source file (auto-detected if not provided).
- `options` (object, optional): Additional options like `template`, `css`, and `preserve_metadata`.

## Configuration

### Using in Trae IDE

Add the following to your Trae IDE MCP configuration:

**Option 1: Using GitHub repository (Recommended)**

```json
{
  "mcpServers": {
    "mcp-document-converter": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/xt765/mcp-document-converter",
        "mcp-document-converter"
      ]
    }
  }
}
```

**Option 2: Using Gitee repository (Faster access in China)**

```json
{
  "mcpServers": {
    "mcp-document-converter": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://gitee.com/xt765/mcp-document-converter",
        "mcp-document-converter"
      ]
    }
  }
}
```

## Usage

### As an MCP Tool

After configuration, AI assistants can directly call the following tools:

#### 1. convert_document (Recommended)

Use a unified interface to convert any supported document type.

```python
# Markdown to HTML
convert_document(
    source_path="document.md",
    target_format="html"
)

# HTML to PDF
convert_document(
    source_path="document.html",
    target_format="pdf"
)

# DOCX to Markdown
convert_document(
    source_path="document.docx",
    target_format="markdown"
)

# Conversion with options
convert_document(
    source_path="document.md",
    target_format="html",
    output_path="output.html",
    options={
        "css": "custom.css",
        "preserve_metadata": True
    }
)
```

#### 2. list_supported_formats

List all supported document formats.

```python
list_supported_formats()
```

#### 3. get_conversion_matrix

Get the complete format conversion matrix.

```python
get_conversion_matrix()
```

#### 4. can_convert

Check if conversion from source format to target format is supported.

```python
can_convert(source_format="markdown", target_format="pdf")
```

#### 5. get_format_info

Get detailed information about a specific format.

```python
get_format_info(format="markdown")
```

### As a Python Library

```python
from mcp_document_converter import DocumentConverter

# Create converter
converter = DocumentConverter(registry)

# Convert document
result = converter.convert(
    source="input.md",
    target_format="html",
    output_path="output.html"
)

if result.success:
    print(f"✅ Conversion successful: {result.output_path}")
else:

### Core Components

1. **DocumentIR (Intermediate Representation)**: Unified abstraction for all documents, containing document tree, metadata, assets, etc.
2. **BaseParser (Parser Base Class)**: Defines the parser interface, parses various formats into DocumentIR
3. **BaseRenderer (Renderer Base Class)**: Defines the renderer interface, renders DocumentIR into various formats
4. **ConverterRegistry (Registry)**: Manages all parsers and renderers, provides format lookup and auto-matching
5. **DocumentConverter (Conversion Engine)**: Coordinates parsers and renderers to complete document conversion

## Extension Development

### Adding a New Parser

```python
from typing import List, Union
from pathlib import Path
from mcp_document_converter.core.parser import BaseParser
from mcp_document_converter.core.ir import DocumentIR, Node, NodeType

class MyParser(BaseParser):
    @property
    def supported_extensions(self) -> List[str]:
        return [".myext"]
    
    @property
    def format_name(self) -> str:
        return "myformat"
    
    @property
    def mime_types(self) -> List[str]:
        return ["application/x-myformat"]
    
    def parse(self, source: Union[str, Path, bytes], **options) -> DocumentIR:
        # Read source file
        content = self._read_source(source)
        
        # Parse into DocumentIR
        document = DocumentIR()
        document.title = "My Document"
        
        # Add content nodes
        document.add_node(Node(
            type=NodeType.PARAGRAPH,
            content=[Node(type=NodeType.TEXT, content="Hello World")]
        ))
        
        return document
```

### Adding a New Renderer

```python
from typing import Any
from mcp_document_converter.core.renderer import BaseRenderer
from mcp_document_converter.core.ir import DocumentIR

class MyRenderer(BaseRenderer):
    @property
    def output_extension(self) -> str:
        return ".myext"
    
    @property
    def format_name(self) -> str:
        return "myformat"
    
    @property
    def mime_type(self) -> str:
        return "application/x-myformat"
    
    def render(self, document: DocumentIR, **options: Any) -> str:
        # Render DocumentIR to target format
        parts = []
        
        if document.title:
            parts.append(f"# {document.title}")
        
        for node in document.content:
            # Render each node
            pass
        
        return "\n".join(parts)
```

### Registering Extensions

```python
from mcp_document_converter.registry import get_registry

# Register new parser and renderer
registry = get_registry()
registry.register_parser(MyParser())
registry.register_renderer(MyRenderer())
```

## Testing

```bash
# Run all tests
python tests/test_conversion.py

# Run specific test
python tests/test_conversion.py::test_markdown_to_html
```
