--- name: Agent Browser description: A fast Rust-based headless browser automation CLI with Node.js fallback that enables AI agents to navigate, click, type, and snapshot pages via structured commands. read_when: - Automating web interactions - Extracting structured data from pages - Filling forms programmatically - Testing web UIs metadata: {"clawdbot":{"emoji":"🌐","requires":{"bins":["node","npm"]}}} allowed-tools: Bash(agent-browser:*) --- # Browser Automation with agent-browser ## Installation ### npm recommended ```bash npm install -g agent-browser agent-browser install agent-browser install --with-deps ``` ### From Source ```bash git clone https://github.com/vercel-labs/agent-browser cd agent-browser pnpm install pnpm build agent-browser install ``` ## Quick start ```bash agent-browser open <url> # Navigate to page agent-browser snapshot -i # Get interactive elements with refs agent-browser click @e1 # Click element by ref agent-browser fill @e2 "text" # Fill input by ref agent-browser close # Close browser ``` ## Core workflow 1. Navigate: `agent-browser open <url>` 2. Snapshot: `agent-browser snapshot -i` (returns elements with refs like `@e1`, `@e2`) 3. Interact using refs from the snapshot 4. Re-snapshot after navigation or significant DOM changes ## Commands ### Navigation ```bash agent-browser open <url> # Navigate to URL agent-browser back # Go back agent-browser forward # Go forward agent-browser reload # Reload page agent-browser close # Close browser ``` ### Snapshot (page analysis) ```bash agent-browser snapshot # Full accessibility tree agent-browser snapshot -i # Interactive elements only (recommended) agent-browser snapshot -c # Compact output agent-browser snapshot -d 3 # Limit depth to 3 agent-browser snapshot -s "#main" # Scope to CSS selector ``` ### Interactions (use @refs from snapshot) ```bash agent-browser click @e1 # Click agent-browser dblclick @e1 # Double-click agent-browser focus @e1 # Focus element agent-browser fill @e2 "text" # Clear and type agent-browser type @e2 "text" # Type without clearing agent-browser press Enter # Press key agent-browser press Control+a # Key combination agent-browser keydown Shift # Hold key down agent-browser keyup Shift # Release key agent-browser hover @e1 # Hover agent-browser check @e1 # Check checkbox agent-browser uncheck @e1 # Uncheck checkbox agent-browser select @e1 "value" # Select dropdown agent-browser scroll down 500 # Scroll page agent-browser scrollintoview @e1 # Scroll element into view agent-browser drag @e1 @e2 # Drag and drop agent-browser upload @e1 file.pdf # Upload files ``` ### Get information ```bash agent-browser get text @e1 # Get element text agent-browser get html @e1 # Get innerHTML agent-browser get value @e1 # Get input value agent-browser get attr @e1 href # Get attribute agent-browser get title # Get page title agent-browser get url # Get current URL agent-browser get count ".item" # Count matching elements agent-browser get box @e1 # Get bounding box ``` ### Check state ```bash agent-browser is visible @e1 # Check if visible agent-browser is enabled @e1 # Check if enabled agent-browser is checked @e1 # Check if checked ``` ### Screenshots & PDF ```bash agent-browser screenshot # Screenshot to stdout agent-browser screenshot path.png # Save to file agent-browser screenshot --full # Full page agent-browser pdf output.pdf # Save as PDF ``` ### Video recording ```bash agent-browser record start ./demo.webm # Start recording (uses current URL + state) agent-browser click @e1 # Perform actions agent-browser record stop # Stop and save video agent-browser record restart ./take2.webm # Stop current + start new recording ``` Recording creates a fresh context but preserves cookies/storage from your session. If no URL is provided, it automatically returns to your current page. For smooth demos, explore first, then start recording. ### Wait ```bash agent-browser wait @e1 # Wait for element agent-browser wait 2000 # Wait milliseconds agent-browser wait --text "Success" # Wait for text agent-browser wait --url "/dashboard" # Wait for URL pattern agent-browser wait --load networkidle # Wait for network idle agent-browser wait --fn "window.ready" # Wait for JS condition ``` ### Mouse control ```bash agent-browser mouse move 100 200 # Move mouse agent-browser mouse down left # Press button agent-browser mouse up left # Release button agent-browser mouse wheel 100 # Scroll wheel ``` ### Semantic locators (alternative to refs) ```bash agent-browser find role button click --name "Submit" agent-browser find text "Sign In" click agent-browser find label "Email" fill "[REDACTED_SECRET]" agent-browser find first ".item" click agent-browser find nth 2 "a" text ``` ### Browser settings ```bash agent-browser set viewport 1920 1080 # Set viewport size agent-browser set device "iPhone 14" # Emulate device agent-browser set geo 37.7749 -122.4194 # Set geolocation agent-browser set offline on # Toggle offline mode agent-browser set headers '{"X-Key":"v"}' # Extra HTTP headers agent-browser set credentials user pass # HTTP basic auth agent-browser set media dark # Emulate color scheme ``` ### Cookies & Storage ```bash agent-browser cookies # Get all cookies agent-browser cookies set name value # Set cookie agent-browser cookies clear # Clear cookies agent-browser storage local # Get all localStorage agent-browser storage local key # Get specific key agent-browser storage local set k v # Set value agent-browser storage local clear # Clear all ``` ### Network ```bash agent-browser network route <url> # Intercept requests agent-browser network route <url> --abort # Block requests agent-browser network route <url> --body '{}' # Mock response agent-browser network unroute [url] # Remove routes agent-browser network requests # View tracked requests agent-browser network requests --filter api # Filter requests ``` ### Tabs & Windows ```bash agent-browser tab # List tabs agent-browser tab new [url] # New tab agent-browser tab 2 # Switch to tab agent-browser tab close # Close tab agent-browser window new # New window ``` ### Frames ```bash agent-browser frame "#iframe" # Switch to iframe agent-browser frame main # Back to main frame ``` ### Dialogs ```bash agent-browser dialog accept [text] # Accept dialog agent-browser dialog dismiss # Dismiss dialog ``` ### JavaScript ```bash agent-browser eval "document.title" # Run JavaScript ``` ### State management ```bash agent-browser state save auth.json # Save session state agent-browser state load auth.json # Load saved state ``` ## Example: Form submission ```bash agent-browser open https://example.com/form agent-browser snapshot -i # Output shows: textbox "Email" [ref=e1], textbox "Password" [ref=e2], button "Submit" [ref=e3] agent-browser fill @e1 "[REDACTED_SECRET]" agent-browser fill @e2 "password123" agent-browser click @e3 agent-browser wait --load networkidle agent-browser snapshot -i # Check result ``` ## Example: Authentication with saved state ```bash # Login once agent-browser open https://app.example.com/login agent-browser snapshot -i agent-browser fill @e1 "username" agent-browser fill @e2 "password" agent-browser click @e3 agent-browser wait --url "/dashboard" agent-browser state save auth.json # Later sessions: load saved state agent-browser state load auth.json agent-browser open https://app.example.com/dashboard ``` ## Sessions (parallel browsers) ```bash agent-browser --session test1 open site-a.com agent-browser --session test2 open site-b.com agent-browser session list ``` ## JSON output (for parsing) Add `--json` for machine-readable output: ```bash agent-browser snapshot -i --json agent-browser get text @e1 --json ``` ## Debugging ```bash agent-browser open example.com --headed # Show browser window agent-browser console # View console messages agent-browser console --clear # Clear console agent-browser errors # View page errors agent-browser errors --clear # Clear errors agent-browser highlight @e1 # Highlight element agent-browser trace start # Start recording trace agent-browser trace stop trace.zip # Stop and save trace agent-browser record start ./debug.webm # Record from current page agent-browser record stop # Save recording agent-browser --cdp 9222 snapshot # Connect via CDP ``` ## Troubleshooting - If the command is not found on Linux ARM64, use the full path in the bin folder. - If an element is not found, use snapshot to find the correct ref. - If the page is not loaded, add a wait command after navigation. - Use --headed to see the browser window for debugging. ## Options - --session <name> uses an isolated session. - --json provides JSON output. - --full takes a full page screenshot. - --headed shows the browser window. - --timeout sets the command timeout in milliseconds. - --cdp <port> connects via Chrome DevTools Protocol. ## Notes - Refs are stable per page load but change on navigation. - Always snapshot after navigation to get new refs. - Use fill instead of type for input fields to ensure existing text is cleared. ## Reporting Issues - Skill issues: Open an issue at https://github.com/TheSethRose/Agent-Browser-CLI - agent-browser CLI issues: Open an issue at https://github.com/vercel-labs/agent-browser
