agent-browser open - Launch the browser, optionally navigate
Usage: agent-browser open [url]
On macOS, installed browsers are searched in /Applications, then ~/Applications.
Without a URL, launches the browser but stays on about:blank. This lets
you stage state (network routes, cookies, init scripts) before the first
real navigation — useful for SSR debug, auth setup, and capturing fresh
`react suspense` / `vitals` state without noise from a prior page.
With a URL, launches and navigates. If no protocol is provided, https://
is automatically prepended. WebMCP tools are announced as brief, untrusted
summaries only on discovery or change. Fetch a selected schema with
`agent-browser webmcp list <tool> --frame <frame-id> --json`. Pages without
tools and unchanged catalogs add no context or discovery polling.
The `goto` and `navigate` aliases still require a URL.
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only
--headers <json> Set HTTP headers (scoped to this origin)
--headed Show browser window
--enable react-devtools Inject the React DevTools hook before any page JS
--init-script <path> Register a page init script (repeatable)
Examples:
agent-browser open # Launch, no nav
agent-browser open example.com
agent-browser open https://github.com
agent-browser open localhost:3000
agent-browser open api.example.com --headers '{"Authorization": "Bearer token"}'
# ^ Headers only sent to api.example.com, not other domains
# Pre-navigation setup in one turn:
agent-browser batch \
"open" \
"network route * --abort --resource-type script" \
"navigate http://localhost:3000/target"
"##
}
"back" => {
r##"
agent-browser back - Navigate back in history
Usage: agent-browser back
Goes back one page in the browser history, equivalent to clicking
the browser's back button.
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only
Examples:
agent-browser back
"##
}
"forward" => {
r##"
agent-browser forward - Navigate forward in history
Usage: agent-browser forward
Goes forward one page in the browser history, equivalent to clicking
the browser's forward button.
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only
Examples:
agent-browser forward
"##
}
"reload" => {
r##"
agent-browser reload - Reload the current page
Usage: agent-browser reload
Reloads the current page, equivalent to pressing F5 or clicking
the browser's reload button.
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only
Examples:
agent-browser reload
"##
}
"read" => {
r##"
agent-browser read - Fetch a URL as agent-readable text
Usage: agent-browser read [url] [--raw] [--require-md] [--llms <index|full>] [--outline] [--filter <text>] [--timeout <ms>]
Fetches a URL as agent-readable text. Omit the URL to read the rendered DOM of
the active tab in the current browser session. Explicit URL reads prefer
markdown with Accept: text/markdown, try the same URL with .md appended when
the first response is not markdown, walk ancestor paths toward / to find the
nearest llms.txt for a matching docs link, fall back to plain text or readable
text extracted from HTML, and print only the document content by default.
Use --outline for a compact heading outline of a single page. Use --llms index
or --llms full for nearest-ancestor llms files; with no URL, --llms and
--require-md use the active tab URL because they depend on HTTP resources.
Options:
--raw Print the response body without HTML extraction
--require-md Fail unless the response is Content-Type: text/markdown
--llms <index|full> Print nearest llms.txt links or llms-full.txt
--outline Print a heading outline for the selected page
--filter <text> Filter page sections, --llms links/sections, or --outline headings
--timeout <ms> Request timeout in milliseconds (default: 10000)
Global Options:
--json Output metadata and content as JSON
--headers <json> Additional HTTP headers, such as Authorization
--allowed-domains <list> Restrict read fetches and redirects to allowed domains
--content-boundaries Wrap read output in boundary markers
--max-output <chars> Truncate read output to N chars
Invalid --max-output and AGENT_BROWSER_MAX_OUTPUT values warn and leave the
existing output limit unchanged.
Examples:
agent-browser read
agent-browser read https://docs.example.com/guide
agent-browser read https://docs.example.com/guide --filter auth
agent-browser read https://docs.example.com/guide --outline
agent-browser read https://docs.example.com --llms index --filter auth
agent-browser read https://docs.example.com --llms full --filter auth
agent-browser read docs.example.com/guide --require-md
agent-browser read https://api.example.com/docs --headers '{"Authorization":"Bearer token"}'
"##
}
"click" => {
r##"
agent-browser click - Click an element
Usage: agent-browser click <selector> [--new-tab] [--human]
Clicks on the specified element. The selector can be a CSS selector,
XPath, or an element reference from snapshot (e.g., @e1).
If another element covers the click point, agent-browser reports the
covering element instead of dispatching a click to the wrong target.
Click and dblclick fail, instead of reporting success, when the element
is hidden, disabled, or outside the viewport. With --new-tab, click opens
the link's URL directly, so these checks do not apply.
Options:
--new-tab Open link in a new tab instead of navigating current tab.
The new tab inherits session setup before its first load.
Only works on elements with an href attribute.
--human Approach along a reproducible eased curve
Starts at the last pointer or element interaction
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only
Examples:
agent-browser click "#submit-button"
agent-browser click @e1
agent-browser click "button.primary"
agent-browser click "//button[@type='submit']"
agent-browser click @e3 --new-tab
agent-browser click @e3 --human
"##
}
"dblclick" => {
r##"
agent-browser dblclick - Double-click an element
Usage: agent-browser dblclick <selector>
Double-clicks on the specified element. Useful for text selection
or triggering double-click handlers.
Double-click fails, instead of reporting success, when the element is
hidden, disabled, or outside the viewport.
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only
Examples:
agent-browser dblclick "#editable-text"
agent-browser dblclick @e5
"##
}
"fill" => {
r##"
agent-browser fill - Clear and fill an input field
Usage: agent-browser fill <selector> [--] <text>
Clears the input field and fills it with the specified text.
This replaces any existing content in the field.
Put flags before --. Text after -- is literal, including values that look like flags.
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only
Examples:
agent-browser fill "#email" "user@example.com"
agent-browser fill @e3 "Hello World"
agent-browser fill "input[name='search']" "query"
agent-browser fill "#search" -- --json
"##
}
"type" => {
r##"
agent-browser type - Type text into an element
Usage: agent-browser type <selector> [--clear] [--delay <ms>] [--] <text>
Types text into the specified element character by character.
Use --clear to clear existing content first. Use --delay to set the delay between keystrokes in milliseconds.
Use -- before text that looks like a flag to pass it literally. Put options before --.
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only
Examples:
agent-browser type "#search" "hello"
agent-browser type @e2 "additional text"
agent-browser --json type "#search" --clear --delay 10 -- --clear

}
"keyboard" => {
r##"
agent-browser keyboard - Raw keyboard input (no selector needed)
Usage: agent-browser keyboard <subcommand> <text>
Sends keyboard input to whatever element currently has focus.
Unlike 'type' which requires a selector, 'keyboard' operates on
the current focus — essential for contenteditable editors like
Lexical, ProseMirror, CodeMirror, and Monaco.
Subcommands:
type <text> Type text character-by-character with real
key events (keydown, keypress, keyup per char)
inserttext <text> Insert text without key events (like paste)
Note: For key combos (Enter, Control+a), use the 'press' command
directly — it already operates on the current focus.

--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only
Examples:
agent-browser keyboard type "Hello, World!"
agent-browser keyboard type "# My Heading"

--text <text> Wait for text to appear on page (substring match)
--download [path] Wait for a download to complete (optionally save to path)
Selector Wait Options:
--state <state> visible, hidden, attached, or detached
Selector waits only; rejected with --url, --load, --fn,
--text, --download, or millisecond waits
--state <path> Global auth state option when placed before wait
A load-state wait uses --timeout (or AGENT_BROWSER_DEFAULT_TIMEOUT) and fails when it expires.
Download Options (with --download):
--timeout <ms> Timeout in milliseconds for download to start
Wait for text to disappear:
Use --fn or --state hidden to wait for text or elements to go away:
wait --fn "!document.body.innerText.includes('Loading...')"
wait "#spinner" --state hidden
wait @e5 --state detached
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only

Captures a screenshot of the current page. If no path is provided,
saves to a temporary directory with a generated filename.
Headless Chromium screenshots hide native scrollbars for consistent image output.
Pass --hide-scrollbars false when launching to keep native scrollbars visible.
Options:
--full, -f Capture full page (not just viewport)
--if-changed Recommended: skip unchanged images to save tokens
--threshold <0-1> Maximum changed-pixel ratio treated as unchanged
(implies --if-changed, default: 0)
--annotate Overlay numbered labels on interactive elements.
Each label [N] corresponds to ref @eN from snapshot.
Prints a legend mapping labels to element roles/names.
With --json, annotations are included in the response.
Supported on Chromium and Lightpanda.
--screenshot-dir <path> Default output directory for screenshots
(or AGENT_BROWSER_SCREENSHOT_DIR env)
--screenshot-quality <0-100> JPEG quality (0-100, only applies to jpeg format)
(or AGENT_BROWSER_SCREENSHOT_QUALITY env)
--screenshot-format <fmt> Image format: png (default) or jpeg
(or AGENT_BROWSER_SCREENSHOT_FORMAT env)
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only

agent-browser snapshot - Get accessibility tree snapshot
Usage: agent-browser snapshot [options]
Returns an accessibility tree representation of the page with element
references (like @e1, @e2) that can be used in subsequent commands.
Refs can be reused across snapshots. Take a fresh snapshot after navigation.
If a ref's element was replaced, the action uses the one element with the same
role and name. If that is ambiguous, it fails: run snapshot again.
Presentational iframes use the Iframe role for snapshots and stale-ref recovery.
Options:
-i, --interactive Only include interactive elements
-u, --urls Include href URLs for link elements
-c, --compact Remove empty structural elements
-d, --depth <n> Limit tree depth
-s, --selector <sel> Scope snapshot to CSS selector
--delta Return full state once, then unchanged or structural deltas
Deltas include ref changes and an exact treeChange line splice
--full Force full state and update the delta baseline
Compact snapshots keep visible text, status text, and their direct ancestors.
Empty sibling branches are removed. Interactive snapshots filter out noninteractive content. MCP snapshots default to interactive; set
interactive to false to retain visible text and status text.
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only

"tab" => {

agent-browser tab - Manage browser tabs
Usage: agent-browser tab [operation] [args]
Manage browser tabs in the current window. Stable tab ids look like `t1`,
`t2`, `t3`. An id is never reused within a session, so scripts can keep
referring to the same tab across commands. Optional user-assigned labels
(e.g. `docs`, `app`) are interchangeable with ids everywhere a tab ref is
accepted. A label starts with a letter and contains only letters, digits, `-`, or
`_`. Labels must be unique within a session and cannot use the reserved `t<N>`
or `T<N>` tab-id form. CDP target ids (from `tab list --json`) are also accepted
as tab refs; unlike `t<N>` ids they stay stable across daemon restarts.
Rejected labels preserve the current tab's refs and selected frame.
Tabs opened with `tab new` or `click --new-tab` inherit the session's user
agent, headers, HTTP credentials, init scripts, routes, and emulation
overrides before their first document loads.
Each session remembers its active tab (bound by CDP target id) and returns
to it after a daemon restart. With --pin-tab, commands fail with a
`tab_gone` error instead of falling back to another tab when the bound tab
is closed. JSON output includes code=tab_gone, data.targetId, and an
optional sanitized data.lastUrl; batch output uses result for the recovery
object. Recover with `tab new` or `tab list`. The pin is sticky per session;
pass --no-pin-tab to turn it off again.
Operations:
list List open tabs with their ids and labels (default)
new [url] Open a new tab
new --label <name> [url] Open a new tab with a label like `docs` or `app`
close [t<N>|label|target] Close a tab (current if no ref given)
<t<N>|label|target> Switch to a tab by id, label, or CDP target id
Global Options:
--json Output as JSON (includes each tab's targetId)
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only
Examples:
agent-browser tab
agent-browser tab list
agent-browser tab new
agent-browser tab new https://example.com
agent-browser tab new --label docs https://docs.example.com

--no-navigate Use the active top-level page without initial navigation
--username-selector <s> Username selector override for this login
--password-selector <s> Password selector override for this login
--submit-selector <s> Submit selector override for this login
Login behavior:
auth login navigates, then waits for form selectors before filling/clicking.
--no-navigate preserves the active top-level page and checks its origin
against the effective credential URL. Submit-triggered navigation is allowed.
Matches are checked for size, computed visibility/opacity, and disabled/readonly
state, including custom selectors.
Replaced or focus-redirected credential fields fail without submitting.
Selector wait timeout follows the default action timeout.
Plugin credentials are resolved just-in-time and are not saved locally.

agent-browser record - Record browser session to video
Usage: agent-browser record start <path.webm|path.mp4> [url] [--fps <n>] [--cursor] [--contact-sheet]
agent-browser record stop
agent-browser record restart <path.webm|path.mp4> [url] [--fps <n>] [--cursor] [--contact-sheet]
Record the browser to a video file. Supported formats are .webm (VP8 via
libvpx) and .mp4 (H.264 via libx264); any other extension is handed to
ffmpeg as-is with H.264 video. A path with no extension is rejected.
Records the current active page as-is: no new context, no new tab, and no
navigation unless you pass a URL. Capture starts on the page you already
have open, so hydration and initial animations are not re-run cold.
If a URL is provided, the active tab navigates there first.
To record in a separate tab, run `tab new [url]` before `record start`.
Requires ffmpeg on PATH with the libvpx and libx264 encoders (brew install
ffmpeg, or apt install ffmpeg). Run `agent-browser doctor` to check.
Recording captures 30 fps, which keeps scrolls and CSS transitions smooth.
Raise it to 60 for short, motion-heavy takes (drag interactions, animation
work); lower it for long sessions where file size matters more than motion.
With --cursor, an inert overlay renders the pointer and page together so
drags stay synchronized. It is hidden from accessibility snapshots and
removed on stop. Screenshots taken while recording include the overlay.
Operations:
start <path> [url] Start recording the active page (navigates first if url given)
stop Stop recording and save video
restart <path> [url] Stop current recording (if any) and start a new one
Options:
--fps <n> Capture rate, 1-60 (default: 30)
--cursor Show an animated pointer
--contact-sheet Save distinct visual changes as a timestamped PNG
--contact-sheet-threshold <n> Changed-pixel ratio, 0-1 (default: 0.05)

"install" => {
r##"
agent-browser install - Install browser binaries
Usage: agent-browser install [--with-deps]
Downloads and installs browser binaries required for automation.
On macOS versions below 13, the command stops before downloading Chrome for
Testing and prints instructions to update macOS or install Chrome manually. If
`sw_vers -productVersion` is unavailable, exits with an error, returns no
version, or returns a malformed version, the command reports a detection error
and stops before making a network request.
Options:
-d, --with-deps Also install Linux system dependencies. The package manager runs
directly as root; non-root uses sudo.
Examples:
agent-browser install
agent-browser install --with-deps
"##
}
"upgrade" => {
r##"
agent-browser upgrade - Upgrade to the latest version
Usage: agent-browser upgrade
Detects the current installation method (npm, Homebrew, or Cargo) and runs
the appropriate update command. Displays the version change on success, or
informs you if you are already on the latest version.
Examples:
agent-browser upgrade
"##
}
"doctor" => {
r##"
agent-browser doctor - Diagnose and repair your install
Usage: agent-browser doctor [options]
Runs a battery of checks across environment, Chrome install, daemon state,
config files, encryption key, providers, network reachability, and a live
headless browser launch test.
Auto-cleans stale daemon socket/pid/version sidecar files. Destructive
repairs (reinstalling Chrome, purging old state files, generating a missing
encryption key) are gated behind --fix.
Options:
--offline Skip network probes
--quick Skip the live headless launch test
--webgpu Also run a live WebGPU render probe (renders via a real
WebGPU pass and pixel-checks both an in-page readback
and a decoded screenshot; launches a second Chrome)
--headed Run the WebGPU probe headed to validate the capture
path (auto-Xvfb on displayless Linux)
--debug Verbose diagnostics from the probes' scratch daemons
--fix Also run destructive repairs
--json JSON output
Exit codes:
0 All checks pass (warnings OK)
1 At least one check failed
Examples:
agent-browser doctor
agent-browser doctor --offline --quick
agent-browser doctor --webgpu
agent-browser doctor --webgpu --headed
agent-browser doctor --fix

"##
}
"dashboard" => {
r##"
agent-browser dashboard - Observability dashboard
Usage: agent-browser dashboard [start|stop] [options]
Manage the observability dashboard, a local web UI that shows live
browser viewports and command activity feeds for all sessions.
The dashboard is bundled into the binary and requires no separate install.
Subcommands:
start [--port <n>] [--allowed-origins <origins>]
Start the dashboard server (default port: 4848)
stop Stop the dashboard server
Running 'agent-browser dashboard' with no subcommand is equivalent to 'dashboard start'.
The dashboard runs as a standalone background process, independent of
browser sessions. All sessions automatically stream to the dashboard.
Loopback origins work without configuration or a token. For a reverse-proxied or
forwarded dashboard, pass --allowed-origins with the exact browser origin
or set AGENT_BROWSER_DASHBOARD_ALLOWED_ORIGINS. The browser stays on the
dashboard origin; session tabs, status, and stream traffic are proxied
internally, so session ports do not need to be exposed.
For reverse-proxied origins, start prints private external access URLs
containing an unguessable fragment token. Open the matching URL to establish
the browser session and do not share it. Loopback URLs do not require or
receive this token. Configure a reverse proxy to redact cookies from logs.
Stop the dashboard before changing its port or allowed origins.
Options:
--port <n> Port for the dashboard server (default: 4848)
--allowed-origins <origins>
Comma-separated exact HTTPS origins allowed when the
dashboard is exposed through a reverse proxy. Loopback
origins are allowed by default. Can also be set with
AGENT_BROWSER_DASHBOARD_ALLOWED_ORIGINS.
Ports must be integers from 1 to 65535. Every allowed origin must be valid.
Unknown options, missing values, and malformed origins fail without starting
the dashboard server.
Global Options:
--json Output as JSON
Examples:
agent-browser dashboard start
agent-browser dashboard start --port 8080
agent-browser dashboard start --allowed-origins https://dashboard.example.com
agent-browser dashboard stop

"connect" => {
r##"
agent-browser connect - Connect to browser via CDP
Usage: agent-browser connect <port|url>
Connects to a running browser instance via Chrome DevTools Protocol (CDP).
This allows controlling browsers, Electron apps, or remote browser services.
Arguments:
<port> Local port number (e.g., 9222)
<url> Full WebSocket URL (ws://, wss://, http://, https://)
Supported URL formats:
- Port number: 9222 (connects to http://localhost:9222)
- WebSocket URL: ws://localhost:9222/devtools/browser/...
- Remote service: wss://remote-browser.example.com/cdp?token=...
- Root endpoint: wss://remote-browser.example.com?token=... (slash optional)
Options:
--cdp-headers <json> Headers for CDP discovery and handshake, e.g. Authorization
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only
Examples:
# Connect to local Chrome with remote debugging
# Start Chrome: google-chrome --remote-debugging-port=9222
agent-browser connect 9222
# Connect using WebSocket URL from /json/version endpoint
agent-browser connect "ws://localhost:9222/devtools/browser/abc123"
# Connect to remote browser service
agent-browser connect "wss://browser-service.example.com/cdp?token=xyz"
# Connect to a service that authenticates the WebSocket handshake
agent-browser connect "wss://browser-service.example.com/cdp" \
--cdp-headers '{"Authorization":"Bearer <token>"}'
# After connecting, run commands normally
agent-browser snapshot

"##
}
"stream" => {
r##"
agent-browser stream - Manage live WebSocket browser streaming
Usage:
agent-browser stream enable [--port <port>]
agent-browser stream disable
agent-browser stream status
Enables or disables the session-scoped WebSocket stream server without restarting
an already-running daemon. If --port is omitted, agent-browser binds an
available localhost port automatically and reports it back.
Notes:
- 'stream enable' creates the WebSocket server.
- WebSocket clients trigger frame streaming automatically.
- On Chrome, URL messages follow full-document, History API, and fragment
navigation in the active tab's main frame. Child-frame and background-tab
navigation does not emit URL messages.
- Frames are delivered latest-first: the newest frame is picked at send
time, so frames produced during an in-flight write are skipped, never
queued. Input events dispatch immediately, independent of frame
delivery, and are sent without waiting for the browser's reply, so a
click stays responsive behind a burst of mouse moves.
- Clients can cap their own frame rate by sending
{"type":"config","maxFps":N} (1-120, 0 = uncapped, per client).
- Clients that send {"type":"config","pacing":"ack"} receive one frame at
a time and acknowledge it with {"type":"ack","seq":N}, so a client that
stalls never drains a backlog of stale frames. Default is "push", where
frames already handed to the transport are delivered in order.
- Both settings can be declared on the URL instead, which is the only way
to cover the opening frame: ws://127.0.0.1:<port>/?pacing=ack&maxFps=10
- 'screencast_start' and 'screencast_stop' still control explicit CDP screencasts.
- Streaming is always enabled. Set AGENT_BROWSER_STREAM_PORT to bind to a
specific port instead of the default OS-assigned port.
Global Options:
--json Output as JSON
--session <name> Session name: Unicode letters/numbers, hyphens, and underscores only
Examples:
agent-browser stream status
agent-browser stream enable
agent-browser stream enable --port 9223
agent-browser stream disable

agent-browser diff - Compare page states
Subcommands:
diff snapshot Compare current snapshot to last snapshot in session
diff screenshot --baseline <f> Visual pixel diff against a baseline image
diff url <url1> <url2> Compare two pages
Snapshot Diff:
Usage: agent-browser diff snapshot [options]
Options:
-b, --baseline <file> Compare against a saved snapshot file
-s, --selector <sel> Scope snapshot to a CSS selector or @ref
-c, --compact Use compact snapshot format
-d, --depth <n> Limit snapshot tree depth
Without --baseline, compares against the last snapshot taken in this session.
Screenshot Diff:
Usage: agent-browser diff screenshot --baseline <file> [options]
Options:
-b, --baseline <file> Baseline image to compare against (required)
-o, --output <file> Path for the diff image (default: temp dir)
-t, --threshold <0-1> Color distance threshold (default: 0.1)

--full Full page screenshots
--wait-until <strategy> Navigation wait strategy: load, domcontentloaded, networkidle (default: load)
-s, --selector <sel> Scope snapshots to a CSS selector or @ref
-c, --compact Use compact snapshot format
-d, --depth <n> Limit snapshot tree depth
Global Options:

"batch" => {
r##"
agent-browser batch - Execute multiple commands sequentially
Usage: agent-browser batch [options] "<cmd1>" "<cmd2>" ...
echo '<json>' | agent-browser batch [options]
Runs multiple commands in sequence. Commands can be passed as quoted
arguments or piped as JSON via stdin. Results are printed in order,
separated by blank lines (or as a JSON array with --json).
Put global flags such as `--init-script` and `--enable` on the outer batch
invocation. Keep command-specific options and literal command arguments inside
each item.
Options:
--bail Stop on first error (default: continue all commands)
--json Output results as a JSON array
--omit-command With --json, replace each command array with a zero-based `index` field
Argument Mode:
Each quoted argument is a full command string:
agent-browser batch "open https://example.com" "snapshot -i" "screenshot"
Stdin Mode (JSON):
A JSON array of string arrays. Each inner array is one command:
[
["open", "https://example.com"],
["snapshot", "-i"],
["click", "@e1"],
["fill", "@e2", "test@example.com"],
["screenshot", "result.png"]
]
Examples:
agent-browser batch "open https://example.com" "screenshot"
agent-browser --enable react-devtools batch "open" "navigate data:text/html,<h1>hi</h1>"
agent-browser batch --bail "open https://example.com" "click @e1" "screenshot"
echo '[["open", "https://example.com"], ["snapshot"]]' | agent-browser batch
echo '[["fill", "#password", "secret"]]' | agent-browser batch --json --omit-command
agent-browser batch --bail < commands.json
With --json --omit-command, each row replaces its command array with a stable zero-based `index` field on success, failure, or --bail. This only removes command arrays and does not make output safe for secrets. Errors and response data are unchanged: type echoes typed text, and get value/eval may return input values.

"a11y" => {
r##"
agent-browser a11y - Run an axe-core accessibility audit
Usage: agent-browser a11y [url] [options]
Audits the current page, or navigates to the optional URL first. The vendored
axe-core engine runs private partial audits without a network request across
the page frame tree, does not trust or replace page-owned window.axe values,
and merges serialized results without page messaging. Accessibility audits
require a CDP browser and are not available with Safari or iOS WebDriver
sessions.
Options:
--tags <tag1,tag2> Run only rules matching these axe tags
-s, --selector <css> Scope the audit to a matching subtree
--json Return structured violations and incomplete results
Structured node targets preserve axe selector paths. Nested arrays identify
shadow DOM boundaries, while multiple path entries can identify frame boundaries.
Examples:
agent-browser a11y
agent-browser a11y https://example.com
agent-browser a11y --tags wcag2a,wcag2aa
agent-browser a11y --selector "#main"
agent-browser a11y https://example.com --json

agent-browser chat - Natural language browser control via AI
Usage:
agent-browser chat <message> Single-shot: execute instruction and exit
agent-browser chat Interactive REPL (when stdin is a TTY)
echo "instruction" | agent-browser chat Piped input
Sends natural language instructions to an AI model that translates them
into agent-browser commands and executes them against the active session.
Requires AI_GATEWAY_API_KEY to be set.
In interactive mode, type "quit", "exit", or "q" to leave the REPL.
Chat Options:
--model <name> AI model (or AI_GATEWAY_MODEL env, default: anthropic/claude-sonnet-4.6)
-v, --verbose Show tool commands and their raw output
-q, --quiet Show only the AI text response (hide tool calls)
Each tool call runs one agent-browser command. Chat can load bundled skills
(skills get <name>) and use page WebMCP tools, fetching a tool's schema with
webmcp list <tool> --frame <frame-id> --json before invoking it in that frame.
Chat runs in the session you select and cannot create or switch sessions. To use
another engine, open the session first with
agent-browser --session <name> --engine <engine> open <url>, then pass --session <name> to chat.
Chat commands cannot set global flags other than --json and --annotate.
Global Options:
--json Structured JSON output per turn
--session <name> Target session: Unicode letters/numbers, hyphens, and underscores only
Examples:
agent-browser chat "open google.com and search for cats"
agent-browser chat "take a screenshot of the current page"
agent-browser -q chat "summarize this page"
agent-browser -v chat "fill in the login form with test@example.com"

agent-browser mcp - Start an MCP stdio server
Usage: agent-browser mcp [--tools <profiles>] [--config <trusted-path>]
agent-browser mcp call <tool> [<arguments-json> | -]
[--tools <profiles>] [--config <trusted-path>]
Starts a Model Context Protocol server over stdio. MCP clients launch this
command as a subprocess and communicate with newline-delimited JSON-RPC.
stdout is reserved for MCP protocol messages; logs and diagnostics use stderr.
The server defaults to MCP protocol 2025-11-25 and accepts older supported
client protocol versions during initialization.
mcp call runs one tool without a stdio session and prints its tools/call
result as JSON, with the agent-browser version in _meta.agentBrowserVersion.
Pass the arguments as a JSON object, or - to read them from stdin. Every tool
is available unless --tools limits the call. Exit code: 0 on success, 1 when
the tool reports an error, 2 for an unknown tool or invalid arguments.
For tool calls that run the CLI, structuredContent.response contains parsed
CLI JSON. stdout is included only when the output cannot be parsed as JSON;
exitCode and stderr are always included.
Pass --config <trusted-path> to agent-browser mcp or agent-browser mcp call to
select one trusted config file. MCP tool child processes load only that file,
replacing default user/project discovery. Put required safety policy in it.
Environment variables and accepted per-tool CLI arguments still override its
values.
The default tools profile is core, which keeps MCP context small for everyday
browser automation. Use --tools all for the full typed CLI parity surface, or
combine profiles with commas, such as --tools core,network,react.
Tool profiles:
core Default. Navigation, snapshots, interaction, waits, reads,
screenshots, JavaScript eval, close, tab basics, and profile discovery
network Network routes, request inspection, HAR, headers, credentials, offline
state Cookies, storage, auth, saved state, sessions, profiles, skills
debug Console/errors, tracing, profiling, recording, accessibility audits,
clipboard, plugins, doctor, dashboard, install, upgrade, chat, diff,
batch, confirm/deny
tabs Back/forward/reload, tabs, windows, frames, dialogs
react React tree/inspect/renders/suspense, vitals, pushstate
mobile Viewport/device/geolocation/media, touch, swipe, mouse, keyboard
all Every MCP tool, including the full typed CLI parity surface
Common tools include:
agent_browser_tools_profiles List MCP startup tool profiles
agent_browser_open Open a URL or launch about:blank
agent_browser_snapshot Get an accessibility snapshot with refs
agent_browser_click Click an element by @ref or selector
agent_browser_fill Fill an input
agent_browser_screenshot Take a screenshot
agent_browser_get_url Read the current URL
agent_browser_close Close the browser session
Each tool has typed fields such as url, selector, text, key, and session.
Each tool also accepts extraArgs for per-command options and display or emulation
flags such as --engine. extraArgs cannot set --config or global flags that change
network, file, policy, or host access. Set host-wide options in the MCP server's
environment or selected config. Structured allowedDomains is rejected when the
server already sets allowed domains.
Tool discovery is paginated and includes read-only/open-world annotations so
modern MCP clients can load the large typed surface incrementally.
Use agent_browser_snapshot after navigation to get fresh refs before clicking.
MCP client config example:
{
"mcpServers": {
"agent-browser": {
"command": "agent-browser",
"args": ["mcp"]

agent-browser skills - List and retrieve bundled skill content
Usage: agent-browser skills [subcommand] [options]
Subcommands:
list List all available skills (default)
get <name> [name...] Output a skill's full content
get <name> --full Include references and templates
get <name> --ref <ref> Output only one reference or template (repeatable)
get --all Output every skill
path [name] Print filesystem path to skill directory
Options:
--json Output as JSON
The skills command serves bundled skill content that always matches the
installed CLI version. Agents should use this to get current instructions
rather than relying on cached copies.
When no package root is found, the CLI reads manually installed skills from ~/.agent-browser/skills and ~/.agent-browser/skill-data.
Package discovery looks for the bundled skill-data/core/SKILL.md file.
Examples:
agent-browser skills
agent-browser skills list
agent-browser skills get core

agent-browser plugin - Manage configured plugins
Usage: agent-browser plugin [subcommand]
Subcommands:
add <ref> Add a plugin from npm or GitHub
list List configured plugins (default)
show <name> Show one configured plugin
run <name> <type> Run a command.run or custom plugin request
Plugins are configured in ~/.agent-browser/config.json or a file loaded with
--config. A plugin entry declares a name, an executable command, optional args,
and capabilities. Plugins run as external processes over the
agent-browser.plugin.v1 stdio JSON protocol.
plugin add writes ~/.agent-browser/config.json by default; use --project for
./agent-browser.json (only used with --config).
Add sources:
<name> npm package, e.g. agent-browser-plugin-captcha
@<scope>/<name> scoped npm package
<owner>/<repo> GitHub repository
Add options:
--name <name> Override the configured plugin name
--capability <name> Declare a capability if the plugin has no manifest
--project Write ./agent-browser.json instead of ~/.agent-browser/config.json
--no-manifest Skip plugin.manifest discovery
plugin add asks the package for plugin.manifest to discover name and
capabilities. Use --capability when adding older plugins without a manifest.
Capabilities:
credential.read Resolve credentials for auth login
browser.provider Launch/connect an external browser provider
launch.mutate Append local launch args, extensions, or init scripts
command.run Accept arbitrary namespaced plugin requests
Core capabilities and protocol request types use dedicated command paths.
Use auth login for credential.read, --provider for browser.provider, and
a local launch for launch.mutate.
Credential, browser-provider, and launch-mutation errors omit response error
text and unsupported protocol values. Manifest discovery and plugin run retain
detailed errors.
Example config:
{{
"plugins": [
{{

Values too large to convert to milliseconds produce a warning and are ignored
--engine <name> Browser engine: chrome (default), lightpanda, obscura (experimental)
(or AGENT_BROWSER_ENGINE); Obscura rejects --proxy-bypass,
proxyBypass config, AGENT_BROWSER_PROXY_BYPASS, NO_PROXY/no_proxy,
--webgpu, --ca-cert, --args, profiles, state, extensions,
headed mode, and file access. Discovery and CDP initialization
each have a 10s deadline plus bounded failure cleanup.
Explicit Obscura launches validate this invocation's resolved
bypass settings, even with an existing daemon; stale daemon
environment values are not reused when bypass is cleared.
Obscura has accessibility, iframe, and screenshot fidelity gaps.

-q, --quiet Show only AI text responses (hide tool calls)
--config <path> Use a custom config file (or AGENT_BROWSER_CONFIG env)
--debug Debug output
--version, -V Show version
Configuration:
Default discovery loads config from these locations (lowest to highest priority):
1. ~/.agent-browser/config.json User-level defaults
2. ./agent-browser.json Allowlisted project defaults
3. Environment variables Override config file values
4. CLI flags Override everything
Use --config <path> to load only that config file instead of default discovery.
AGENT_BROWSER_CONFIG has the same effect. Environment variables and CLI flags
still override values from the selected config file.
If --config points to a missing or invalid file, agent-browser exits with an error.
The auto-discovered ./agent-browser.json accepts only:
{project_config_keys}.
Other runtime keys, including extensions, initScripts, state, trust, policy,
session, connection, and path settings, are ignored with a warning.
The $schema metadata key is ignored silently.
Put advanced settings in ~/.agent-browser/config.json or load a trusted file
with --config or AGENT_BROWSER_CONFIG.
Boolean flags accept an optional true/false value to override config:
--headed (same as --headed true)
--headed false (disables "headed": true from config)
--hide-scrollbars false (keeps native scrollbars visible in headless Chromium screenshots)
The auto-discovered project config ignores extensions. Use the user config, an
explicitly loaded config file, AGENT_BROWSER_EXTENSIONS, or --extension.
On Windows, headless Chrome runs on a private desktop to prevent stray desktop
rectangles. Owned Chrome processes close with their daemon, even if it is killed.
Headed browsers use the interactive desktop; externally connected browsers are not owned.
Example auto-discovered agent-browser.json:
{{"headed": true, "hideScrollbars": false, "userAgent": "my-agent/1.0", "colorScheme": "dark"}}
Trusted config example (user config or a file loaded with --config):
{{"plugins":[{{"name":"vault","command":"agent-browser-plugin-vault","capabilities":["credential.read"]}},{{"name":"stealth","command":"agent-browser-plugin-stealth","capabilities":["launch.mutate"]}}]}}
