## 🚀 Quick Start

### Prerequisites

- Python 3.10+
- MCP SDK
- Playwright

### Installation

```bash
# Install MCP and Playwright
pip install mcp playwright

# Install browser dependencies
playwright install
```

### Configuration for Claude Desktop

Add to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "web-browser": {
      "command": "python",
      "args": [
        "/path/to/your/server.py"
      ]
    }
  }
}
```

## 💡 Usage Examples

### Basic Web Navigation

```python
# Browse to a website
page_content = browse_to("https://example.com")

# Extract page text
text_content = extract_text_content()

# Extract text from a specific element
title_text = extract_text_content("h1.title")
```

### Web Interaction

```python
# Navigate to a page
browse_to("https://example.com/login")

# Input text into a form
input_text("#username", "your_username")
input_text("#password", "your_password")

# Click a login button
click_element("#login-button")
```

### Screenshot Capture

```python
# Capture full page screenshot
full_page_screenshot = get_page_screenshots(full_page=True)

# Capture specific element screenshot
element_screenshot = get_page_screenshots(selector="#main-content")
```

### Link Extraction

```python
# Get all links on the page
page_links = get_page_links()

# Get links matching a pattern
filtered_links = get_page_links(filter_pattern="contact")
```

### Multi-Tab Browsing

```python
# Create a new tab
tab_id = create_new_tab("https://example.com")

# Create another tab
another_tab_id = create_new_tab("https://example.org")

# List all open tabs
tabs = list_tabs()

# Switch between tabs
switch_tab(tab_id)

# Close a tab
close_tab(another_tab_id)
```

### Advanced Interactions

```python
# Scroll the page
scroll_page(direction="down", amount="page")

# Execute JavaScript on the page
result = execute_javascript("return document.title")

# Get detailed page information
page_info = get_page_info()

# Refresh the current page
refresh_page()

# Wait for navigation to complete
wait_for_navigation(timeout_ms=5000)
```
