* feat: add --allow-file-access flag for file:// URL support
Adds the ability to open and interact with local files using file:// URLs.
This enables use cases like viewing local PDFs, testing local HTML files,
and allowing JavaScript to access other local files via XHR.
The flag adds Chromium's --allow-file-access-from-files and --allow-file-access
launch arguments. Only supported in Chromium browsers.
Fixes#345
* fix: add cli_allow_file_access tracking to prevent spurious warning
When --allow-file-access is set via AGENT_BROWSER_ALLOW_FILE_ACCESS env var
(not CLI), don't warn about the flag being ignored when daemon is already running.
* fix: only warn about ignored flags when explicitly passed via CLI
The warning about launch-time options being ignored (when daemon is
already running) was incorrectly shown when options were set via
environment variables like AGENT_BROWSER_EXECUTABLE_PATH, even when
no CLI flag was passed.
Now the warning only appears when flags are explicitly passed on the
command line, not when values come solely from environment variables.
Fixes#372
* feat: add cursor-interactive element detection in snapshots
Add -C/--cursor flag to snapshot command that detects clickable elements
that don't have proper ARIA roles but are interactive based on:
- cursor: pointer CSS style
- onclick attribute/handler
- tabindex attribute
This helps with modern web apps that use custom divs/spans as buttons.
Fixes#366
* fix: add cursor option to getSnapshot type signature
* fix(cli): save screenshots to tmp dir when no path provided
Instead of outputting base64 to stdout (which is not useful for most CLI use cases),
screenshots without a path now save to ~/.agent-browser/tmp/screenshots/ with a
generated filename and return the path.
This makes the behavior more ergonomic for AI agents and CLI users alike.
* cleanup
* cleanup
* just revert the cargo.lock version for now
* refactor: extract getAppDir() from getSocketDir()
* docs: improve screenshot help text consistency
Add Kernel (https://kernel.sh) as a third-party cloud browser provider,
following the same pattern as Browserbase and Browser Use integrations.
Features:
- Launch browser with `-p kernel` flag or `AGENT_BROWSER_PROVIDER=kernel`
- Configurable via environment variables:
- KERNEL_API_KEY (required)
- KERNEL_HEADLESS (default: false)
- KERNEL_STEALTH (default: true)
- KERNEL_TIMEOUT_SECONDS (default: 300)
- KERNEL_PROFILE_NAME (optional, for persistent sessions)
- Profile find-or-create: automatically creates profile if it doesn't exist
- Profile persistence: cookies/logins saved back to profile on session close
- Uses raw fetch() calls for API communication (no SDK dependency)

* feat: add support for ignoring HTTPS certificate errors
* fix: update warning message for already running daemon to include ignore HTTPS errors option
* docs: add documentation for --ignore-https-errors option in README and SKILL.md
* feat: initialize ignore_https_errors flag in command context
* fix: change launch_cmd to mutable for cdp value handling
* fix: download artifacts to temp directory to avoid naming conflict
The download-artifact action creates directories named after each artifact.
When downloading to bin/, this caused conflicts because the artifact directory
names matched the binary names (e.g., bin/agent-browser-darwin-arm64/agent-browser-darwin-arm64).
Fix by downloading to artifacts/ first, then using find to move the binaries to bin/.
* fix docs
* Add --profile flag for persistent browser profiles
Adds support for persistent browser profiles that preserve cookies,
localStorage, and login sessions across browser restarts.
Changes:
- Add --profile <path> CLI flag (flags.rs)
- Add AGENT_BROWSER_PROFILE environment variable support
- Add profile field to LaunchCommand type (types.ts)
- Use launchPersistentContext when profile is specified (browser.ts)
- Update help text and README with documentation
Usage:
agent-browser --profile ~/.myapp-profile open myapp.com
This enables AI agents to maintain authenticated sessions across
browser restarts without re-authenticating each time.
* Expand tilde in profile path to home directory
* fix: add missing profile field to test Flags struct

Previously, the --cdp flag only accepted a port number and connected via
http://localhost:{port}. This made it impossible to connect to remote
browser services like Kernel, Browserless, etc. that provide WebSocket URLs.
The --cdp flag now accepts either:
- A port number (e.g., 9222) for local connections
- A full WebSocket URL (e.g., wss://...) for remote browser services
Changes:
- Added cdpUrl field to LaunchCommand type
- Updated protocol validation to accept URL format with scheme validation
- Modified connectViaCDP to detect and handle both formats
- Handle numeric strings for JSON serialization edge cases
- Updated CLI to send cdpUrl or cdpPort based on input format
- Updated README with examples for remote connections

* feat: add Browser Use cloud browser
integration
* feat: enhance Browser Use integration with provider flag support
- Updated README to reflect new usage instructions for enabling Browser Use with the `-p` flag.
- Modified CLI to parse and handle the `-p` flag for specifying the provider.
- Implemented logic in the main application to launch with the specified cloud provider.
- Adjusted BrowserManager to connect to Browser Use based on the provider flag or environment variable.
- Updated types and protocol schemas to include provider information.
* feat: add validation for mutually exclusive CLI options
- Implemented checks to prevent the use of both --cdp and --provider flags simultaneously.
- Added validation to ensure --extension cannot be used with the --provider flag.
- Enhanced error handling to provide clear feedback in both JSON and console output formats.
* Add Browserbase support for remote browser over CDP
When BROWSERBASE_API_KEY and BROWSERBASE_PROJECT_ID env vars are set,
connect to a Browserbase session via CDP instead of launching a local browser.
* Update URLs to browserbase repo
* Add Browserbase support for remote browser over CDP
When BROWSERBASE_API_KEY and BROWSERBASE_PROJECT_ID env vars are set,
connect to a Browserbase session via CDP instead of launching a local browser.
* Update link to Browserbase Dashboard in README
* bump browserbase sdk to latest version
* remove sdk as a dep
* change name back to vercel labs
* added try catch blocks, functions to close session
* revert package names
* remove extra if statement

Adds a `connect <port>` command that establishes a CDP connection
to a running browser. The daemon remembers the connection, so
subsequent commands work without needing --cdp on every call.
Example:
agent-browser connect 9222
agent-browser snapshot # works without --cdp
agent-browser tab
agent-browser close
* fix(cli): print screenshot base64 when no path
* chore(docs): update docs and SKILL.md
* add test for screenshot with path arg
* more minimal readme + skill change

* feat: add CDP connection support for external browsers
Add --cdp flag to connect to browsers via Chrome DevTools Protocol.
This enables control of Electron apps, Chrome instances, or any browser
exposing a CDP endpoint.
- Add cdpPort option to launch command schema
- Implement connectViaCDP() using chromium.connectOverCDP()
- Track browser connection type for proper reconnection handling
- Collect all pages from all contexts for CDP connections
Usage: agent-browser --cdp 9222 snapshot

* fix: verify CDP connection is alive before early return in launch()
Prevents misleading errors when the remote browser crashes by checking
isConnected() before reusing an existing browser reference.

* fix: reconnect when CDP port changes instead of reusing existing browser
Ensures --cdp flag is respected even when a browser session already exists.
