Using AgentCore Browser with Nova Act

You can build a browser agent using Nova Act to automate web interactions:

Step 1: Install dependencies

Create a project folder (if you have not already):

mkdir agentcore-browser-quickstart
cd agentcore-browser-quickstart
python3 -m venv .venv
source .venv/bin/activate

Install the required packages:

pip install bedrock-agentcore nova-act rich boto3

These packages provide:

Step 2: Get Nova Act API Key

Navigate to Nova Act page and generate an API key using your amazon.com credentials. (Note this currently works only for US based amazon.com accounts)

Create a file named nova_act_browser_agent.py and add the following code:

Write a browser agent using Nova Act

The following Python code shows how to write a browser agent using Nova Act. For information about obtaining the API key for Nova Act, see Amazon Nova Act documentation.

from bedrock_agentcore.tools.browser_client import browser_session
from nova_act import NovaAct
from rich.console import Console
import argparse
import json
import boto3

console = Console()

from boto3.session import Session

boto_session = Session()
region = boto_session.region_name
print("using region", region)

def browser_with_nova_act(prompt, starting_page, nova_act_key, region="us-west-2"):
    result = None
    with browser_session(region) as client:
        ws_url, headers = client.generate_ws_headers()
        try:
            with NovaAct(
                cdp_endpoint_url=ws_url,
                cdp_headers=headers,
                nova_act_api_key=nova_act_key,
                starting_page=starting_page,
            ) as nova_act:
                result = nova_act.act(prompt)
        except Exception as e:
            console.print(f"NovaAct error: {e}")
        finally:
            return result


if __name__ == "__main__":
    parser = argparse.ArgumentParser()
    parser.add_argument("--prompt", required=True, help="Browser Search instruction")
    parser.add_argument("--starting-page", required=True, help="Starting URL")
    parser.add_argument("--nova-act-key", required=True, help="Nova Act API key")
    parser.add_argument("--region", default="us-west-2", help="AWS region")
    args = parser.parse_args()

    result = browser_with_nova_act(
        args.prompt, args.starting_page, args.nova_act_key, args.region
    )
    console.print(f"\n[cyan] Response[/cyan] {result.response}")
    console.print(f"\n[bold green]Nova Act Result:[/bold green] {result}")

Step 3: Run the agent

Execute the script (Replace with your Nova Act API key in the command):

python nova_act_browser_agent.py --prompt "What are the common usecases of Bedrock AgentCore?" --starting-page "https://docs.aws.amazon.com/bedrock-agentcore/latest/devguide/what-is-bedrock-agentcore.html" --nova-act-key "your-nova-act-API-key"

Expected output

You should see the agent's response containing details of the common usecases of Amazon Bedrock AgentCore. The agent navigates the website, performs the search, and extracts the requested information.

If you encounter errors, verify:

Step 4: View the browser session live

While your browser script is running, you can view the session in real-time through the AWS Console:

The live view interface provides:
