class langchain_community.agent_toolkits.playwright.toolkit.PlayWrightBrowserToolkit

Bases: BaseToolkit

Toolkit for PlayWright browser tools.

Security Note: This toolkit provides code to control a web-browser.

Careful if exposing this toolkit to end-users. The tools in the toolkit are capable of navigating to arbitrary webpages, clicking on arbitrary elements, and extracting arbitrary text and hyperlinks from webpages.

Specifically, by default this toolkit allows navigating to:

• Any URL (including any internal network URLs)

• And local files

If exposing to end-users, consider limiting network access to the server that hosts the agent; in addition, consider it is advised to create a custom NavigationTool wht an args_schema that limits the URLs that can be navigated to (e.g., only allow navigating to URLs that start with a particular prefix).

Remember to scope permissions to the minimal permissions necessary for the application. If the default tool selection is not appropriate for the application, consider creating a custom toolkit with the appropriate tools.

See https://python.langchain.com/docs/security for more information.

Create a new model by parsing and validating input data from keyword arguments.

Raises ValidationError if the input data cannot be parsed to form a valid model.

param async_browser: Optional['AsyncBrowser'] = None

param sync_browser: Optional['SyncBrowser'] = None

classmethod construct(_fields_set: Optional[SetStr] = None, **values: Any) → Model

Creates a new model setting __dict__ and __fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed. Behaves as if Config.extra = ‘allow’ was set since it adds all passed values

Parameters

• _fields_set (Optional[SetStr]) –

• values (Any) –

Return type

Model

copy(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, update: Optional[DictStrAny] = None, deep: bool = False) → Model

Duplicate a model, optionally choose which fields to include, exclude and change.

Parameters

• include (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to include in new model

• exclude (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to exclude from new model, as with values this takes precedence over include

• update (Optional[DictStrAny]) – values to change/add in the new model. Note: the data is not validated before creating the new model: you should trust this data

• deep (bool) – set to True to make a deep copy of the model

• self (Model) –

Returns

new model instance

Return type

Model

dict(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, by_alias: bool = False, skip_defaults: Optional[bool] = None, exclude_unset: bool = False, exclude_defaults: bool = False, exclude_none: bool = False) → DictStrAny

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

Parameters
