AWS Bedrock AgentCore
Run agent-browser on cloud browser sessions hosted by AWS Bedrock AgentCore. All standard agent-browser commands work identically; the only difference is where the browser runs.
Setup
Credentials are resolved automatically:
- Environment variables (
AWS_ACCESS_KEY_ID,AWS_SECRET_ACCESS_KEY, optionallyAWS_SESSION_TOKEN) - AWS CLI fallback (
aws configure export-credentials), which supports SSO, IAM roles, and named profiles
No additional setup is needed if the user already has working AWS credentials.
Core Workflow
# Open a page on an AgentCore cloud browser
agent-browser -p agentcore open https://example.com
# Everything else is the same as local Chrome
agent-browser snapshot -i
agent-browser click @e1

Environment Variables
| Variable | Description | Default |
|---|---|---|
AGENTCORE_REGION | AWS region | us-east-1 |
AGENTCORE_BROWSER_ID | Browser identifier | aws.browser.v1 |
AGENTCORE_PROFILE_ID | Persistent browser profile (cookies, localStorage) | (none) |
AGENTCORE_SESSION_TIMEOUT | Session timeout in seconds | 3600 |
AWS_PROFILE | AWS CLI profile for credential resolution | default |
Persistent Profiles
Use AGENTCORE_PROFILE_ID to persist browser state across sessions. This is useful for maintaining login sessions:
# First run: log in
AGENTCORE_PROFILE_ID=my-app agent-browser -p agentcore open https://app.example.com/login
agent-browser snapshot -i
agent-browser fill @e1 "[email protected]"
agent-browser fill @e2 "password"
agent-browser click @e3
agent-browser close
# Future runs: already authenticated
AGENTCORE_PROFILE_ID=my-app agent-browser -p agentcore open https://app.example.com/dashboard
Live View
When a session starts, AgentCore prints a Live View URL to stderr. Open it in a browser to watch the session in real time from the AWS Console:
Session: abc123-def456
Live View: https://us-east-1.console.aws.amazon.com/bedrock-agentcore/browser/aws.browser.v1/session/abc123-def456#
Region Selection
# Default: us-east-1
agent-browser -p agentcore open https://example.com
# Explicit region
AGENTCORE_REGION=eu-west-1 agent-browser -p agentcore open https://example.com
Credential Patterns
# Explicit credentials (CI/CD, scripts)
export AWS_ACCESS_KEY_ID=AKIA...
export AWS_SECRET_ACCESS_KEY=...
agent-browser -p agentcore open https://example.com
# SSO (interactive)
aws sso login --profile my-profile
AWS_PROFILE=my-profile agent-browser -p agentcore open https://example.com
# IAM role / default credential chain
agent-browser -p agentcore open https://example.com
Using with AGENT_BROWSER_PROVIDER
Set the provider via environment variable to avoid passing -p agentcore on every command:
export AGENT_BROWSER_PROVIDER=agentcore
export AGENTCORE_REGION=us-east-2
agent-browser open https://example.com
agent-browser snapshot -i
agent-browser click @e1
agent-browser close
Common Issues
"Failed to run aws CLI" means AWS CLI is not installed or not in PATH. Either install it or set AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY directly.
"AWS CLI failed: ... Run 'aws sso login'" means SSO credentials have expired. Run aws sso login to refresh them.
Session timeout: The default is 3600 seconds (1 hour). For longer tasks, increase with AGENTCORE_SESSION_TIMEOUT=7200.
