stealthy-auto-browse

Browser automation in Docker built for QA against anti-bot stacks, compatibility testing of detection libraries (CreepJS, BrowserScan, Pixelscan, Cloudflare), and defensive security research where standard headless browsers produce false-positive blocks. Uses Camoufox (custom Firefox, no CDP signals) + PyAutoGUI for OS-level input.

For installation, configuration, and container setup, see references/setup.md.

Security & safety

  • Authorized targets only. This tool is built for QA/testing against sites and systems you own or have written authorization to test — not for scraping or automating third-party sites without permission. See "Authorized Use Only" below before pointing it at anything.
  • Data capture is powerful — scope it. get_text, get_html, get_interactive_elements, eval, and the screenshot/save_screenshot actions can extract full page content, DOM structure, and rendered pixels in one call. Only capture what the authorized test actually needs; don't sweep pages outside scope just because the API makes it easy.
  • Dialogs auto-accept by default — this can approve destructive actions. confirm(), beforeunload, and permission prompts are accepted automatically unless you called handle_dialog with accept: false first. An agent must disable or scope auto-accept (call handle_dialog with accept: false before any step that might raise a dialog) whenever it is acting on a stateful site (one with real data, real accounts, or irreversible actions behind a confirm prompt), and must never drive this tool against a site where an accidental confirm would be harmful. See "Dialogs" below.
  • No auth when AUTH_TOKEN is unset. With it empty the HTTP API and MCP surface are UNAUTHENTICATED — anyone who can reach the port gets full browser control (navigation, input, cookies, screenshots, script execution). NEVER expose such an instance beyond localhost; set AUTH_TOKEN and bind to 127.0.0.1 or put it behind an authenticating proxy. See references/setup.md.
  • Loaders execute automatically on matching URLs. Only mount loader YAML you wrote or audited — see "Page Loaders" below.

Authorized Use Only

This tool is intentionally hard to fingerprint as automation. That makes it dangerous if misused. Only use it for:

  • Sites you own or operate
  • Sites you have written authorization to test (security engagements, bug bounty in-scope targets)
  • Your own anti-bot / fraud detection stack for QA and regression testing
  • Detection-library research in a controlled environment
  • Compatibility testing where legitimate automation is being misclassified as malicious

Do not use this to evade access controls, scrape sites against their ToS, automate logged-in activity on accounts you don't own, abuse rate limits, or bypass CAPTCHAs you weren't authorized to bypass. Many jurisdictions criminalize unauthorized access regardless of technical means. The maintainers are not responsible for misuse.

If you're unsure whether your use case is authorized, it isn't. Stop and get written permission first.

When To Use

  • Validating that your own anti-bot rules behave correctly under realistic automation
  • Compatibility / regression testing where another headless browser is wrongly flagged
  • Authorized pentests / bug bounty on in-scope targets that require human-like interaction
  • Maintaining a stable test session against your own site or a sanctioned staging environment

When NOT To Use

  • Any site you don't own or aren't explicitly authorized to test
  • Scraping content protected by ToS, paywalls, or rate limits
  • Driving real (non-test) user accounts on third-party services
  • Static HTML — use curl or WebFetch
  • Sites with no detection layer — use a normal browser skill

Setup

The API should already be running. Set the base URL:

export STEALTHY_AUTO_BROWSE_URL=http://127.0.0.1:8080

Verify: curl $STEALTHY_AUTO_BROWSE_URL/health returns ok.

Recommended defaults: bind to 127.0.0.1, set AUTH_TOKEN to a strong random value, do not expose port 5900 to anything beyond localhost, and pin the container image by digest. See references/setup.md.

HTTP API

All commands: POST $STEALTHY_AUTO_BROWSE_URL/ with JSON body {"action": "name", ...params}.

AUTH_TOKEN is required for any non-localhost deployment. When set, include it on every request (except /health):

Authorization: Bearer <key>

Query-string authentication is not supported because URLs leak into logs.

In single-instance mode, requests are serialized automatically — only one runs at a time, the rest queue up.

Every response:

{
  "success": true,
  "timestamp": 1234567890.123,
  "data": { ... },
  "error": "only when success is false"
}

Two Input Modes

System Input — OS-Level Events

Uses PyAutoGUI for real OS-level mouse/keyboard events. The browser doesn't see synthetic DOM events. Use only for legitimate detection-stack testing where DOM-event automation is incorrectly blocked.

  • system_click — move mouse with human-like curve, then click (viewport x,y coords)
  • mouse_move — move mouse without clicking (hover menus, tooltips)
  • mouse_click — click at position or current location (no smooth movement)
  • system_type — type text character-by-character with randomized delays
  • send_key — press a key or combo (enter, tab, ctrl+a)
  • scroll — mouse wheel scroll (negative = down)

Get viewport coordinates from get_interactive_elements.

Playwright Input — DOM Events

Uses Playwright's DOM events. Faster, uses CSS selectors/XPath, distinguishable as automation.

  • click — click by selector
  • fill — set input value instantly
  • type — type into element character-by-character

Which To Use

  • Clicking: always try click with a CSS selector first — fast and reliable. Only fall back to system_click if your authorized test target requires OS-level input. system_click requires calibrate first or coordinates will be wrong.
  • Typing: fill for inputs (fast). system_type only when OS-level input is genuinely required by the test target.
  • No detection layer in scope? Playwright input (click, fill) is fine.
  • Testing OS-input behavior of your own detection stack? System input + calibrate first.

Typical Workflow

  1. goto → load the page
  2. get_text → read what's on the page
  3. get_interactive_elements → find buttons/inputs with selectors and x,y coords
  4. click (CSS selector) → interact; fall back to system_click only when test scope requires
  5. wait_for_element / wait_for_text → wait for results
  6. get_text → verify

Actions Reference

Navigation

{"action": "goto", "url": "https://example.com"}
{"action": "goto", "url": "https://example.com", "wait_until": "networkidle"}
{"action": "goto", "url": "https://example.com", "referer": "https://google.com/search?q=stuff"}
{"action": "refresh"}
{"action": "refresh", "wait_until": "networkidle"}

wait_until: "domcontentloaded" (default), "load", "networkidle". referer: set HTTP Referer header (for sites that check referrer).

Response: {"url": "...", "title": "..."}

System Input (OS-Level)

{"action": "system_click", "x": 500, "y": 300}
{"action": "system_click", "x": 500, "y": 300, "duration": 0.5}
{"action": "mouse_move", "x": 500, "y": 300}
{"action": "mouse_click", "x": 500, "y": 300}
{"action": "mouse_click"}
{"action": "system_type", "text": "hello world", "interval": 0.08}
{"action": "send_key", "key": "enter"}
{"action": "send_key", "key": "ctrl+a"}
{"action": "scroll", "amount": -3}
{"action": "scroll", "amount": -3, "x": 500, "y": 300}

Playwright Input (DOM Events)

{"action": "click", "selector": "#submit-btn"}
{"action": "click", "selector": "xpath=//button[@id='submit']"}
{"action": "fill", "selector": "input[name='email']", "value": "user@example.com"}
{"action": "type", "selector": "#search", "text": "query", "delay": 0.05}

Page Inspection

Combined with screenshots (below) and script/run_script mode, these actions let one call extract full page text, DOM structure, and rendered pixels — powerful data capture. Use only against authorized targets and only pull what the test actually needs; this is not a general-purpose scraping tool for sites you don't have permission to collect from.

{"action": "get_interactive_elements"}
{"action": "get_interactive_elements", "visible_only": true}
{"action": "get_text"}
{"action": "get_html"}
{"action": "get_page_info"}
{"action": "get_element", "selector": "main article"}
{"action": "get_elements", "selector": "main article a", "limit": 25}
{"action": "get_computed_style", "selector": "main article", "properties": ["display", "font-size"]}
{"action": "eval", "expression": "document.title"}
{"action": "eval", "expression": "document.querySelectorAll('a').length"}

get_interactive_elements returns all buttons, links, inputs with x, y, w, h, text, selector, visible. Pass x, y directly to system_click.

get_text returns visible page text (truncated to 10,000 chars). Call this first after navigating.

For structured extraction, use get_element for one matching node or get_elements for a bounded list. get_page_info returns document/viewport state, and get_computed_style exposes selected CSS values without a custom JavaScript expression.

Virtual Camera and Microphone

For authorized camera/microphone compatibility tests, mount test media at /media and configure VIRTUAL_CAMERA_FILE and/or VIRTUAL_MICROPHONE_FILE before the browser starts. A page's navigator.mediaDevices.getUserMedia() call then receives tracks captured from those files. A request for an unconfigured kind fails with NotFoundError rather than falling back to hardware. This virtualizes streams only; it does not add native devices to enumerateDevices(). Source files must remain within VIRTUAL_MEDIA_DIR (default /media) and the browser must restart after static-source changes.

Set VIRTUAL_MEDIA_DYNAMIC=true to switch file-backed sources at runtime. set_virtual_media_source takes kind ("camera" or "microphone") plus an existing relative source name; upload_virtual_media takes kind, a safe filename whose declared media type matches that kind, strict base64 content_base64, and optional activate. The filename supplies only the extension: the service generates and returns a collision-safe stored basename and never overwrites a named source. It checks decoded uploads with ffprobe for the requested video or audio stream before storage or activation. Uploads are limited to VIRTUAL_MEDIA_UPLOAD_MAX_BYTES (50 MiB by default) and need a writable VIRTUAL_MEDIA_DIR. Already acquired page streams retain their track identities after a source switch. Only files inside the configured media directory are accepted—never arbitrary paths, remote URLs, WebSocket streams, or other live ingress. These actions require the same Bearer authorization as every other action when AUTH_TOKEN is set. See references/setup.md.

Screenshots

# Browser viewport
curl -s "$STEALTHY_AUTO_BROWSE_URL/screenshot/browser?whLargest=512" -o screenshot.png

# Full desktop
curl -s "$STEALTHY_AUTO_BROWSE_URL/screenshot/desktop?whLargest=512" -o desktop.png

Resize params: whLargest=512 (recommended), width=800, height=300, width=400&height=400.

Via action (for script mode — returns base64 with output_id):

{"action": "save_screenshot"}
{"action": "save_screenshot", "type": "desktop"}
{"action": "save_screenshot", "output_id": "my_screenshot", "whLargest": 512}
{"action": "save_screenshot", "path": "/output/page.png"}

Screen Recording

Captures actual rendered pixels (ffmpeg x11grab against the Xvfb display) including the OS-level mouse cursor — PyAutoGUI moves are visible. One active recording per container; a second start_recording while one is active returns an error. Requires /recordings mounted as a host volume — see references/setup.md. If not mounted (or not writable), start_recording fails fast.

{"action": "start_recording"}
{"action": "start_recording", "mode": "viewport", "fps": 30}
{"action": "start_recording", "mode": "desktop", "show_cursor": false}
{"action": "recording_status"}
{"action": "stop_recording", "slug": "my-flow"}

mode: "window" (default, full Camoufox window incl. chrome), "viewport" (crops chrome using the calibrated window_offset — lazy-recalibrates if unset), "desktop" (entire Xvfb screen). fps: 1–60, default 15. show_cursor: bool, default true — set false to record without the OS-level cursor sprite.

start_recording returns recording_id, tmp_path, show_cursor, capture_size. stop_recording finalizes and renames the tmp file to /recordings/<slug>.mp4 — slug must match [a-zA-Z0-9][a-zA-Z0-9_-]{0,62} (no path traversal); a colliding slug is saved as <slug>-2.mp4, etc. Returns path, duration_s, size_bytes. recording_status returns {"active": true, "recording_id", "mode", "started_at", "elapsed_s", "tmp_path"} when recording, {"active": false} otherwise.

Encoder: H.264 (libx264), -preset ultrafast, -crf 28, yuv420p — tuned for low CPU over file size on browser footage.

Cluster mode: recording actions are only usable from inside run_script — outside, the script-only restriction rejects them. start_recording and stop_recording must live in the SAME run_script call so both hit the same browser instance:

{"action": "run_script", "steps": [
    {"action": "start_recording", "mode": "viewport", "fps": 20},
    {"action": "goto", "url": "https://example.com", "wait_until": "networkidle"},
    {"action": "stop_recording", "slug": "example-page"}
]}

calibrate after enter_fullscreen/exit_fullscreen or any chrome-state change so a following viewport recording crops at the right line.

Wait Conditions

Use these instead of sleep.

{"action": "wait_for_element", "selector": "#results", "state": "visible", "timeout": 10}
{"action": "wait_for_text", "text": "Search results", "timeout": 10}
{"action": "wait_for_url", "url": "**/dashboard", "timeout": 10}
{"action": "wait_for_network_idle", "timeout": 30}

state: "visible" (default), "hidden", "attached", "detached".

Tabs

{"action": "list_tabs"}
{"action": "new_tab", "url": "https://example.com"}
{"action": "switch_tab", "index": 0}
{"action": "close_tab", "index": 1}

Dialogs

⚠️ Dialogs are auto-accepted by default. If a scripted step raises an unexpected confirm() / beforeunload / permission prompt, it WILL be accepted automatically — which can confirm a destructive or irreversible action. When a run might hit a dialog you don't want accepted, call handle_dialog with accept: false BEFORE the triggering action, and review your scripts for steps that could raise one.

Agent guardrail: when driving a stateful site (real accounts, real data, or any confirm/permission prompt that could trigger an irreversible action), disable or scope auto-accept first — call handle_dialog with accept: false before the step that might raise the dialog, and only re-enable acceptance for a specific, expected prompt you intend to approve. Never run this tool against a site where an accidental confirm would be harmful.

Call handle_dialog BEFORE the action that triggers the dialog.

{"action": "handle_dialog", "accept": true}
{"action": "handle_dialog", "accept": false}
{"action": "handle_dialog", "accept": true, "text": "prompt response"}
{"action": "get_last_dialog"}

Cookies

{"action": "get_cookies"}
{"action": "get_cookies", "urls": ["https://example.com"]}
{"action": "set_cookie", "name": "session", "value": "abc", "url": "https://example.com"}
{"action": "delete_cookies"}

Storage

{"action": "get_storage", "type": "local"}
{"action": "set_storage", "type": "local", "key": "theme", "value": "dark"}
{"action": "clear_storage", "type": "local"}

type: "local" (default) or "session".

Downloads & Uploads

{"action": "get_last_download"}
{"action": "upload_file", "selector": "#file-input", "file_path": "/tmp/doc.pdf"}

Network Logging

{"action": "enable_network_log"}
{"action": "get_network_log"}
{"action": "clear_network_log"}
{"action": "getclear_network_log"}
{"action": "disable_network_log"}

Console Logging

Capture console.log, console.error, console.warn, etc. Each entry has type, text, location, timestamp.

{"action": "enable_console_log"}
{"action": "get_console_log"}
{"action": "clear_console_log"}
{"action": "getclear_console_log"}
{"action": "disable_console_log"}

Scrolling

{"action": "scroll_to_bottom", "delay": 0.4}
{"action": "scroll_to_bottom_humanized", "min_clicks": 2, "max_clicks": 6, "delay": 0.5}

scroll_to_bottom uses JS (fast). scroll_to_bottom_humanized uses OS-level mouse wheel.

Display

{"action": "calibrate"}
{"action": "get_resolution"}
{"action": "enter_fullscreen"}
{"action": "exit_fullscreen"}

Call calibrate after fullscreen changes.

Multi-Step Scripts

Run multiple actions as one atomic request. Steps with output_id collect results.

{"action": "run_script", "steps": [
    {"action": "goto", "url": "https://example.com", "wait_until": "domcontentloaded"},
    {"action": "sleep", "duration": 2},
    {"action": "get_text", "output_id": "text"},
    {"action": "eval", "expression": "document.title", "output_id": "title"}
]}

Also accepts "yaml": "..." with the same YAML format used in script mode.

on_error: "stop" (default) or "continue".

Utility

{"action": "ping"}
{"action": "sleep", "duration": 2}
{"action": "close"}

State Endpoints (GET)

curl $STEALTHY_AUTO_BROWSE_URL/health     # "ok" when ready
curl $STEALTHY_AUTO_BROWSE_URL/state      # {"status", "url", "title", "window_offset"}

MCP Server

The browser exposes all actions as MCP tools via Streamable HTTP at /mcp/ on the same port as the HTTP API.

http://127.0.0.1:8080/mcp/

Connect any MCP-compatible client to that URL. All actions from the HTTP API are available as tools — dedicated tools include goto, screenshot, system_click, system_type, eval_js, get_text, click, fill, run_script (multi-step), and browser_action (generic fallback for everything else — cookies, tabs, storage, dialogs, downloads, logging, recording, and more).

If AUTH_TOKEN is set, configure the MCP client to send Authorization: Bearer <key> when connecting to http://127.0.0.1:8080/mcp/.

Works in both standalone and cluster mode. In cluster mode, only run_script is available (same restriction as HTTP API).

Cluster Mode

Run multiple browser instances behind HAProxy with a request queue, sticky sessions, and Redis cookie sync. For setup see references/setup.md.

Entry point is http://127.0.0.1:8080 — same API. HAProxy queues requests when all instances are busy instead of returning errors.

Script-only enforcement (v1.0.0+): When NUM_REPLICAS > 1, both the HTTP API and MCP server only allow run_script, ping, and sleep. All other individual actions are rejected. Use run_script to bundle multiple actions into a single atomic request — one request = one routing decision = one browser instance handles the entire sequence. All actions remain available as steps inside run_script.

Sticky sessions: HAProxy sets an INSTANCEID cookie. Send it back on subsequent requests to keep routing to the same browser instance. All browser state (tabs, DOM, JS, local storage) lives on that specific container — only cookies sync via Redis.

Redis cookie sync: Cookies set on any instance propagate to all others instantly via PubSub. Authenticate once against your own test target, the whole fleet shares the session.

Script Mode

Pipe a YAML script via stdin, get JSON results on stdout, container exits. No HTTP server.

cat my-script.yaml | docker run --rm -i \
  -e TARGET_URL=https://example.com \
  psyb0t/stealthy-auto-browse@sha256:7ce5d42ddb3b7fdbfb4af2d4bf6072f5a862d5dd2b64c7feb496e493f587223c \
  --script > results.json

Replace the digest with the one you've reviewed for the version you're running (docker pull psyb0t/stealthy-auto-browse:v1.0.0 && docker inspect --format='{{index .RepoDigests 0}}' psyb0t/stealthy-auto-browse:v1.0.0).

Script Format

name: Scrape Example
on_error: stop    # "stop" (default) or "continue"
steps:
  - action: goto
    url: ${env.TARGET_URL}
    wait_until: networkidle
  - action: sleep
    duration: 2
  - action: save_screenshot
    output_id: screenshot
  - action: get_text
    output_id: page_text
  - action: eval
    expression: "document.title"
    output_id: title

Output

{
  "name": "Scrape Example",
  "success": true,
  "steps_executed": 5,
  "steps_total": 5,
  "duration": 3.42,
  "step_results": [ ... ],
  "outputs": {
    "screenshot": "data:image/png;base64,iVBOR...",
    "page_text": { "text": "...", "length": 1234 },
    "title": { "result": "Example Domain" }
  }
}
  • output_id on any step collects its result into outputs. Screenshots become base64 data URIs.
  • ${env.VAR_NAME} substitutes environment variables.
  • on_error: continue keeps going past failures. stop (default) halts.
  • All HTTP API actions work as script steps.
  • Logs go to stderr, stdout is clean JSON.
  • Exit code 0 on success, 1 on failure.

Example: Screenshot + Extract (against your own site)

cat <<'EOF' | docker run --rm -i -e URL=https://staging.your-site.example \
  psyb0t/stealthy-auto-browse@sha256:7ce5d42ddb3b7fdbfb4af2d4bf6072f5a862d5dd2b64c7feb496e493f587223c \
  --script > results.json
name: Quick Scrape
steps:
  - action: goto
    url: ${env.URL}
    wait_until: networkidle
  - action: save_screenshot
    output_id: screenshot
    whLargest: 1024
  - action: get_text
    output_id: text
  - action: eval
    expression: "document.title"
    output_id: title
EOF

Page Loaders (URL-Triggered Automation)

Mount YAML files to /loaders. When goto hits a matching URL, the loader's steps execute instead of normal navigation. Works in both API and script mode.

⚠️ Loaders run automatically the moment a matching URL is visited — with no fresh confirmation at that point — and their steps can modify page state (eval, clicks, form fills). Only mount loaders you wrote or audited, and review every loader YAML before mounting it. Don't mount loader files from an untrusted source.

docker run -d -p 127.0.0.1:8080:8080 -v ./my-loaders:/loaders \
  psyb0t/stealthy-auto-browse@sha256:7ce5d42ddb3b7fdbfb4af2d4bf6072f5a862d5dd2b64c7feb496e493f587223c

In script mode:

cat script.yaml | docker run --rm -i \
  -v ./my-loaders:/loaders \
  psyb0t/stealthy-auto-browse@sha256:7ce5d42ddb3b7fdbfb4af2d4bf6072f5a862d5dd2b64c7feb496e493f587223c \
  --script

Loader Format

name: News Site Cleanup
match:
  domain: news-site.com       # exact hostname (www. stripped)
  path_prefix: /articles      # path starts with
  regex: "article/\\d+"       # full URL regex
steps:
  - action: goto
    url: "${url}"              # ${url} = original URL
    wait_until: networkidle
  - action: eval
    expression: "document.querySelector('.cookie-banner')?.remove()"
  - action: wait_for_element
    selector: "article"
    timeout: 10

Match fields are optional but at least one is required. All specified fields must match.

Account & Session Hygiene

Persistent profiles let cookies, sessions, and fingerprints survive restarts. Use them responsibly:

  • Test accounts only. Provision isolated accounts dedicated to QA on your own systems. Never persist sessions for real (production / personal / customer) accounts you don't own.
  • Treat the profile volume as a secret. It contains live session cookies — back it up encrypted or not at all, and shred it (rm -rf ./profile) when the test run is done.
  • Don't share profile volumes across environments. A profile built against staging shouldn't be reused against prod or vice versa.
  • Rotate credentials after authorized testing concludes if the same accounts are used by humans too.

Tips

  1. Read text, not pixels — always try get_text or get_html first; screenshots are last resort
  2. Screenshots: use whLargest=512 — full resolution wastes tokens; fine detail is rarely needed
  3. Prefer click with CSS selector — reliable and fast; use system_click only when scope requires OS-level input
  4. calibrate before system_click — without it, coordinates are wrong and clicks miss
  5. Always get_interactive_elements before clicking — gets both selectors and coordinates
  6. Match TZ to IP location — timezone mismatch is a fingerprint inconsistency that breaks realistic test scenarios
  7. Wait conditions over sleep — wait_for_element, wait_for_text, wait_for_url
  8. handle_dialog BEFORE the trigger — dialogs are auto-accepted otherwise
  9. calibrate after fullscreen — coordinate mapping shifts
