# Website Tools

> WebsiteTools exposes a read_url function to read a website's contents, or an add_website_to_knowledge function when a Knowledge instance is passed in.

**WebsiteTools** enable an Agent to read a website's contents, or to add them to a knowledge base when one is provided.

## Prerequisites

The following example requires the `beautifulsoup4` library.

```shell theme={null}
uv pip install -U beautifulsoup4 openai
```

## Example

The following agent will read the contents of a website.

```python cookbook/91_tools/website_tools.py theme={null}
from agno.agent import Agent
from agno.tools.website import WebsiteTools

agent = Agent(tools=[WebsiteTools()])
agent.print_response("Search web page: 'https://docs.agno.com/introduction'", markdown=True)
```
