Headless browser automation via MCP using Playwright WebKit.

## Install ### Homebrew (macOS / Linux) ```bash brew install saiden-dev/tap/browse npx playwright install webkit ``` ### npm ```bash npm install @saiden/browse npx playwright install webkit ``` ## CLI Usage ```bash # Take a screenshot browse https://example.com # Custom viewport and output browse -o page.png -w 1920 -h 1080 https://example.com # Query elements browse -q "a[href]" https://example.com browse -q "img" -j https://example.com # JSON output # Click and interact browse -c "button.submit" https://example.com browse -t "input[name=q]=hello" -c "button[type=submit]" https://google.com # Chain actions browse -c ".cookie-accept" -c "a.nav-link" -q "h1" https://example.com # Interactive mode (visible browser) browse -i --headed https://example.com # Fullscreen mode (macOS native fullscreen) browse --fullscreen -i https://example.com # Preview mode (highlights elements before actions) browse -p -c "button.submit" https://example.com browse -p --preview-delay 3000 -c ".nav-link" https://example.com ``` ## MCP Server Add to your MCP client config (e.g., `~/.claude/settings.json` or project `.mcp.json`): ```json { "mcpServers": { "browse": { "command": "npx", "args": ["browse-mcp"] } } } ``` Or run directly: ```bash browse-mcp ``` ### MCP Tools Reference **Browser Lifecycle:** | Tool | Description | |------|-------------| | `launch` | Launch browser with options (headed, fullscreen, preview, viewport) | | `close` | Close the browser and end session | **Navigation & Interaction:** | Tool | Description | |------|-------------| | `goto` | Navigate to a URL | | `click` | Click on an element | | `type` | Type text into an input field | | `hover` | Hover over an element | | `select` | Select option(s) in a dropdown | | `keys` | Send keyboard shortcuts (e.g., "Enter", "Control+a") | | `scroll` | Scroll page or element into view | | `upload` | Upload files to a file input | | `back`, `forward`, `reload` | Browser navigation | | `wait` | Wait for a specified time | **Debugging & Inspection:** | Tool | Description | |------|-------------| | `console` | Get captured console messages (log, warn, error, etc.) | | `errors` | Get page errors (uncaught exceptions) | | `network` | Get captured network requests/responses | | `intercept` | Block or mock network requests | | `metrics` | Get performance metrics and DOM statistics | | `a11y` | Get accessibility tree snapshot | **Page Content:** | Tool | Description | |------|-------------| | `query` | Query elements by CSS selector | | `screenshot` | Take a screenshot | | `url` | Get current URL and title | | `html` | Get page HTML content | | `eval` | Execute JavaScript in browser context | **Storage & Session:** | Tool | Description | |------|-------------| | `cookies` | Get, set, delete, or clear cookies | | `storage` | Access localStorage or sessionStorage | | `dialog` | Configure how browser dialogs are handled | | `session_save` | Save session state to file | | `session_restore` | Restore session from file | | `import` | Import cookies from Safari (macOS, requires Full Disk Access) | **Viewport & Emulation:** | Tool | Description | |------|-------------| | `viewport` | Resize browser viewport | | `emulate` | Emulate a mobile device | **Image Processing:** | Tool | Description | |------|-------------| | `favicon` | Generate favicon set from image | | `convert` | Convert image format | | `resize` | Resize image | | `crop` | Crop image | | `compress` | Compress image | | `thumbnail` | Create thumbnail | ### MCP Resources | Resource | Description | |----------|-------------| | `browser://state` | Browser state (URL, title, launched) | | `browser://html` | Page HTML (truncated to 10KB) | | `browser://html/full` | Complete page HTML | | `browser://console` | Captured console messages | | `browser://network` | All network requests | | `browser://network/failed` | Failed requests only | | `browser://errors` | Page errors | | `browser://a11y` | Accessibility tree | | `browser://screenshot` | Page screenshot as base64 PNG | ## Programmatic Usage ```typescript import { ClaudeBrowser } from '@saiden/browse'; const browser = new ClaudeBrowser({ headless: true, // Set false to show browser window width: 1280, height: 800, fullscreen: false, // macOS native fullscreen (implies headless: false) preview: false, // Highlight elements before actions previewDelay: 2000, // Preview highlight duration in ms }); await browser.launch(); await browser.goto('https://example.com'); const elements = await browser.query('a[href]'); console.log(elements); await browser.click('button.submit'); await browser.type('#input', 'hello'); await browser.screenshot('page.png'); await browser.close(); ``` ## API ### ClaudeBrowser **Lifecycle:** - `launch()` - Launch the browser - `close()` - Close the browser - `newPage()` - Open new page **Navigation:** - `goto(url)` - Navigate to URL - `back()` / `forward()` / `reload()` - Browser navigation - `wait(ms)` - Wait for timeout **Interaction:** - `click(selector)` - Click element - `type(selector, text)` - Type into input - `hover(selector)` - Hover over element - `select(selector, value)` - Select dropdown option(s) - `keys(keys)` - Press keyboard keys - `scroll(selector?, x?, y?)` - Scroll page or element - `upload(selector, files)` - Upload files **Content:** - `query(selector)` - Query elements, returns attributes - `screenshot(path?, fullPage?)` - Take screenshot - `getUrl()` - Get current URL and title - `getHtml(full?)` - Get page HTML - `eval(script)` - Execute JavaScript **Debugging:** - `getConsole(level?, clear?)` - Get console messages - `getErrors(clear?)` - Get page errors - `getNetwork(filter?, clear?)` - Get network requests - `getMetrics(includeResources?)` - Get performance metrics - `getA11y(selector?)` - Get accessibility tree **Storage:** - `getCookies(name?)` - Get cookies - `setCookie(name, value, url?)` - Set cookie - `deleteCookie(name)` / `clearCookies()` - Remove cookies - `getStorage(type, key?)` - Get localStorage/sessionStorage - `setStorage(type, key, value)` - Set storage item - `deleteStorage(type, key)` / `clearStorage(type)` - Remove storage **Interception:** - `addIntercept(pattern, action, response?)` - Block or mock requests - `clearIntercepts()` - Remove all intercepts **Viewport:** - `setViewport(width, height)` - Resize viewport - `emulate(device)` - Emulate device (e.g., 'iPhone 13') **Commands:** - `executeCommand(cmd)` - Execute a command object ## AI Agent Disclaimer AI agents may scan, analyze, and use this code provided they comply with the BSL-1.1 license terms.
