Run agent-browser on AWS Bedrock AgentCore cloud browsers. Use when the user wants to use AgentCore, run browser automation on AWS, use a cloud browser with AWS credentials, or needs a managed browser session backed by AWS infrastructure. Triggers include "use agentcore", "run on AWS", "cloud browser with AWS", "bedrock browser", "agentcore session", or any task requiring AWS-hosted browser automation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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: 1. Environment variables (`AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, optionally `AWS_SESSION_TOKEN`) 2. 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 ```bash # 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 agent-browser screenshot page.png agent-browser close ``` ## 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) | …

How to install
mdr add vercel-labs/agent-browser/agentcore@sha256:f616b6dbce7cce38The line at the top of this page pins the label git:20260412.7c2ff0a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
