What is Amazon Bedrock AgentCore Browser?
Amazon Bedrock AgentCore Browser is a managed, cloud-based browser that developers can give to an AI agent. It is infrastructure for running browser sessions, not one Amazon assistant that independently decides which sites to visit.
AWS documents an isolated environment where an agent can navigate web applications, click controls, fill forms, take screenshots, and extract information. The developer can use the AWS-managed browser or create a custom browser with its own network and recording settings. The particular application and user instruction determine why a website receives traffic.
A session can contain many requests because the browser works through an interactive flow. AWS provides live viewing, CloudWatch metrics, and session replay or recording options for observing that work. From the website's side, requests may look more like an ordinary browser journey than a crawler repeatedly downloading documents.
AgentCore Browser does not by itself index pages for AI search or collect a model training dataset. Any content it reads is used according to the agent application that opened the session. It is also separate from Amazon Bedrock's web crawler for knowledge bases, which uses bedrockbot identifiers and publishes its own robots.txt behavior.
The facts record contains no stable user-agent token and no Cloudflare catalog entry for AgentCore Browser. AWS does offer Web Bot Auth, but browser signing is disabled by default and must be enabled when a custom browser is created. When enabled, AgentCore signs HTTP requests and sends Signature, Signature-Agent, and Signature-Input headers for verification.
No robots.txt commitment is recorded for AgentCore Browser. A signed request proves the identity represented by the signature; it does not require a site to allow that request. AWS notes that site owners may still block, monitor, or rate-limit signed traffic, and not every bot-control provider or website will recognize it.
