- **Image Operations**: Add images and extract images from PDFs
- **Annotations**: Add various types of annotations (text, highlight, underline, etc.)
- **Form Fields**: Add and fill form fields
- **Page Manipulation**: Merge, split, rotate, delete, and crop pages
- **Auto-Crop**: Automatically detect and crop content boundaries
- **Page Combination**: Combine multiple pages into single pages with various layouts
- **Metadata**: Get and set PDF metadata

## How to Configure with Cursor IDE

### Step 1: Install the Server

Follow the installation steps above to set up the MCP server.

### Step 2: Configure Cursor IDE

Add this configuration to your Cursor settings:

**Option A: Using an MCP config and uvx:**

Create `~/.cursor/mcp_config.json`:

```json
{
  "mcpServers": {
    "pdf-manipulation": {
      "command": "uvx",
      "args": ["--from", "pdf-manipulation-mcp-server", "pdf-mcp-server"]
    }
  }
}
```
**Option B: Using MCP Config File from a local installation**

Create `~/.cursor/mcp_config.json`:

```json
{
  "mcpServers": {
    "pdf-manipulation": {
      "command": "uv",
      "args": ["run", "python", "server.py"],
      "cwd": "/path/to/pdf-manipulation-mcp-server"
    }
  }
}
```

**Option C: Using Cursor Settings UI**
1. Open Cursor Settings (`Cmd+,` on Mac, `Ctrl+,` on Windows/Linux)
2. Search for "MCP" in settings
3. Add this configuration:

```json
{
  "mcp.servers": {
    "pdf-manipulation": {
      "command": "uv",
      "args": ["run", "python", "server.py"],
      "cwd": "/path/to/pdf-manipulation-mcp-server"
    }
  }
}
```

### Step 3: Restart Cursor IDE

After adding the configuration, restart Cursor IDE to load the MCP server.

### Step 4: Test the Integration

1. Open a new chat in Cursor
2. Try these commands:
   - "Convert this PDF to Markdown"
   - "Add text to a PDF"
   - "Extract images from a PDF"
   - "Merge multiple PDFs"

## Usage Examples

### Basic PDF Auto-Crop Workflow

```python
# Automatically crop PDF pages to remove margins
result = await pdf_auto_crop_page(
    pdf_path="document.pdf",
    padding=10.0
)

# Crop specific page with coordinates
result = await pdf_crop_page(
    pdf_path="document.pdf",
    page_number=0,
    x0=50, y0=50, x1=400, y1=300,
    coordinate_mode="bbox"
)
```

### Adding Text to PDF

```python
result = await pdf_add_text(
    pdf_path="document.pdf",
    page_number=0,
    text="New text content",
    x=100,
    y=100,
    font_size=14,
    color=[1, 0, 0]  # Red color
)
```

### Working with Images

```python
# Add image to PDF
result = await pdf_add_image(
    pdf_path="document.pdf",
    page_number=0,
    image_path="image.png",
    x=100,
    y=200,
    width=200,
    height=150
)

# Extract all images from PDF
result = await pdf_extract_images(
    pdf_path="document.pdf",
    output_dir="extracted_images"
)
```

### Page Manipulation

```python
# Merge multiple PDFs
result = await pdf_merge_files(
    pdf_paths=["doc1.pdf", "doc2.pdf", "doc3.pdf"]
)

# Combine pages from a single PDF
result = await pdf_combine_pages_to_single(
    pdf_path="document.pdf",
    page_numbers=[0, 1, 2],
    layout="vertical"
)

# Split PDF into individual pages
result = await pdf_split(
    pdf_path="document.pdf",
    output_dir="split_pages"
)

# Rotate a page
result = await pdf_rotate_page(
    pdf_path="document.pdf",
    page_number=0,
    rotation=90
)
```

```

### Running Tests

```bash
# Test the MCP server
uv run python test_mcp_server.py

# Run the server
uv run python server.py
```

### Dependencies

- **`mcp`** - Official MCP SDK for Python
- **`pymupdf`** - Core PDF manipulation library
- **`pytest`** - Testing framework (dev dependency)
- **`pytest-asyncio`** - Async testing support (dev dependency)

## File Safety

All operations create new files with timestamps to avoid overwriting originals. Output files follow the pattern: `{original_name}_{operation}_{timestamp}.pdf`

## Error Handling

The server includes comprehensive error handling:
- Validates PDF files before operations
- Checks page numbers and coordinates
- Provides clear error messages
- Handles missing files gracefully
- Catches and reports PyMuPDF exceptions

## Troubleshooting

### Common Issues

1. **"No tools" in Cursor settings**: This is normal! Tools appear in the chat interface, not in settings.

2. **UV not found**: Install UV first:
   ```bash
   curl -LsSf https://astral.sh/uv/install.sh | sh
   ```

3. **Python version error**: UV will automatically install Python 3.11+ if needed.

4. **Dependencies not found**: Make sure you're using UV:
   ```bash
   uv pip install mcp pymupdf
   ```

### Debug Mode

To run the server in debug mode:

```bash
uv run python server.py --debug
```
