Browser-use remote-browser

Controls a local browser from a sandboxed remote machine. Use when the agent is running in a sandbox (no GUI) and needs to navigate websites, interact with web pages, fill forms, take screenshots, or expose local dev servers via tunnels.

Browser Automation for Sandboxed Agents

This skill is for agents running on sandboxed remote machines (cloud VMs, CI, coding agents) that need to control a headless browser.

Prerequisites

browser-use doctor    # Verify installation

For setup details, see https://github.com/browser-use/browser-use/blob/main/browser_use/skill_cli/README.md

Core Workflow

  1. Navigate: 
    browser-use open <url>
    — starts headless browser if needed
  2. Inspect: 
    browser-use state
    — returns clickable elements with indices
  3. Interact: use indices from state (
    browser-use click 5
    , 
    browser-use input 3 "text"
    )
  4. Verify: 
    browser-use state
    or 
    browser-use screenshot
    to confirm
  5. Repeat: browser stays open between commands
  6. Cleanup: 
    browser-use close
    when done

Browser Modes

browser-use open <url>                                    # Default: headless Chromium
browser-use cloud connect                                 # Provision cloud browser and connect
browser-use --connect open <url>                          # Auto-discover running Chrome via CDP
browser-use --cdp-url ws://localhost:9222/... open <url>  # Connect via CDP URL

Commands

# Navigation
browser-use open <url>                    # Navigate to URL
browser-use back                          # Go back in history
browser-use scroll down                   # Scroll down (--amount N for pixels)
browser-use scroll up                     # Scroll up
browser-use tab list                      # List all tabs with lock status
browser-use tab new [url]                 # Open a new tab (blank or with URL)
browser-use tab switch <index>            # Switch to tab by index
browser-use tab close <index> [index...]  # Close one or more tabs

# Page State — always run state first to get element indices
browser-use state                         # URL, title, clickable elements with indices
browser-use screenshot [path.png]         # Screenshot (base64 if no path, --full for full page)

# Interactions — use indices from state
browser-use click <index>                 # Click element by index
browser-use click <x> <y>                 # Click at pixel coordinates
browser-use type "text"                   # Type into focused element
browser-use input <index> "text"          # Click element, then type
browser-use keys "Enter"                  # Send keyboard keys (also "Control+a", etc.)
browser-use select <index> "option"       # Select dropdown option
browser-use upload <index> <path>         # Upload file to file input
browser-use hover <index>                 # Hover over element
browser-use dblclick <index>              # Double-click element
browser-use rightclick <index>            # Right-click element

# Data Extraction
browser-use eval "js code"                # Execute JavaScript, return result
browser-use get title                     # Page title
browser-use get html [--selector "h1"]    # Page HTML (or scoped to selector)
browser-use get text <index>              # Element text content
browser-use get value <index>             # Input/textarea value
browser-use get attributes <index>        # Element attributes
browser-use get bbox <index>              # Bounding box (x, y, width, height)

# Wait
browser-use wait selector "css"           # Wait for element (--state visible|hidden|attached|detached, --timeout ms)
browser-use wait text "text"              # Wait for text to appear

# Cookies
browser-use cookies get [--url <url>]     # Get cookies (optionally filtered)
browser-use cookies set <name> <value>    # Set cookie (--domain, --secure, --http-only, --same-site, --expires)
browser-use cookies clear [--url <url>]   # Clear cookies
browser-use cookies export <file>         # Export to JSON
browser-use cookies import <file>         # Import from JSON

# Python — persistent session with browser access
browser-use python "code"                 # Execute Python (variables persist across calls)
browser-use python --file script.py       # Run file
browser-use python --vars                 # Show defined variables
browser-use python --reset                # Clear namespace

# Session
browser-use close                         # Close browser and stop daemon
browser-use sessions                      # List active sessions
browser-use close --all                   # Close all sessions

The Python 

browser
object provides: 
browser.url
, 
browser.title
, 
browser.html
, 
browser.goto(url)
, 
browser.back()
, 
browser.click(index)
, 
browser.type(text)
, 
browser.input(index, text)
, 
browser.keys(keys)
, 
browser.upload(index, path)
, 
browser.screenshot(path)
, 
browser.scroll(direction, amount)
, 
browser.wait(seconds)
.

Tunnels

Expose local dev servers to the browser via Cloudflare tunnels.

browser-use tunnel <port>                 # Start tunnel (idempotent)
browser-use tunnel list                   # Show active tunnels
browser-use tunnel stop <port>            # Stop tunnel
browser-use tunnel stop --all             # Stop all tunnels

Command Chaining

Commands can be chained with 

&&
. The browser persists via the daemon, so chaining is safe and efficient.

browser-use open https://example.com && browser-use state
browser-use input 5 "user@example.com" && browser-use input 6 "password" && browser-use click 7

Chain when you don't need intermediate output. Run separately when you need to parse 

state
to discover indices first.

Common Workflows

Exposing Local Dev Servers

python -m http.server 3000 &                      # Start dev server
browser-use tunnel 3000                            # → https://abc.trycloudflare.com
browser-use open https://abc.trycloudflare.com     # Browse the tunnel

Tunnels are independent of browser sessions and persist across 

browser-use close
.

Multi-Agent (--connect mode)

Multiple agents can share one browser via 

--connect
. Each agent gets its own tab — other agents can't interfere.

Setup: Register once, then pass the index with every 

--connect
command:

INDEX=$(browser-use register)                    # → prints "1"
browser-use --connect $INDEX open <url>          # Navigate in agent's own tab
browser-use --connect $INDEX state               # Get state from agent's tab
browser-use --connect $INDEX click <element>     # Click in agent's tab
  • Tab locking: When an agent mutates a tab (click, type, navigate), that tab is locked to it. Other agents get an error if they try to mutate the same tab.
  • Read-only access: 
    state
    , 
    screenshot
    , 
    get
    , and 
    wait
    commands work on any tab regardless of locks.
  • Agent sessions expire after 5 minutes of inactivity. Run 
    browser-use register
    again to get a new index.

Global Options

OptionDescription
--headed
Show browser window
--connect
Auto-discover running Chrome via CDP
--cdp-url <url>
Connect via CDP URL (
http://
or 
ws://
)
--session NAME
Target a named session (default: "default")
--json
Output as JSON

Tips

  1. Always run 
    state
    first     to see available elements and their indices
  2. Sessions persist — browser stays open between commands until you close it
  3. Tunnels are independent — they persist across 
    browser-use close
  4. tunnel
    is idempotent     — calling again for the same port returns the existing URL

Troubleshooting

  • Browser won't start? 
    browser-use close
    then retry. Run 
    browser-use doctor
    to check.
  • Element not found? 
    browser-use scroll down
    then 
    browser-use state
  • Tunnel not working? 
    which cloudflared
    to check, 
    browser-use tunnel list
    to see active tunnels

Cleanup

browser-use close                         # Close browser session
browser-use tunnel stop --all             # Stop tunnels (if any)
