## 🚀 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)
```

## 🛡️ Security Features

- SSL certificate validation bypass
- Secure browser context management
- Custom user-agent configuration
- Error handling and comprehensive logging
- Configurable timeout settings
- CSP bypass control
- Protection against cookie stealing

## 🔧 Troubleshooting

### Common Issues

- **SSL Certificate Errors**: Automatically bypassed

TDQS

A3.7/5.0

Scored across 6 tools

Disambiguation5/5

Each tool has a clearly distinct purpose with no overlap: navigation, clicking, text extraction, link extraction, screenshot capture, and text input. The descriptions reinforce these distinct functions, making it easy for an agent to select the right tool for each task without confusion.

Naming Consistency4/5

The tools follow a consistent verb_noun or verb_adjective_noun pattern (e.g., browse_to, click_element, extract_text_content), with all names using snake_case. The only minor deviation is 'get_page_links' and 'get_page_screenshots' using 'get' instead of a more specific verb like 'extract', but this is still readable and maintains overall consistency.

Tool Count5/5

With 6 tools, this server is well-scoped for basic web browsing automation, covering essential actions like navigation, interaction, and content extraction. Each tool earns its place without being overly complex or insufficient for the domain, making it manageable and effective for typical use cases.

Completeness4/5

The toolset provides solid coverage for core web browsing tasks, including navigation, interaction (clicking and input), and content extraction (text, links, screenshots). A minor gap is the lack of tools for more advanced actions like form submission, scrolling, or handling pop-ups, but agents can likely work around this with the existing tools for most workflows.
