Hey everyone, it's Shii-chan! Today's news is about agents getting finer control over their web searches — let's take a look!

What was announced?

This comes from AWS What's New. Amazon Bedrock AgentCore's Web Search tool now supports domain filtering and published-date filtering. AgentCore is the infrastructure for building, connecting, and optimizing AI agents, and Web Search is what lets those agents ground their answers in current web data.

The story so far

Web Search could already ground agents in fresh web data, but there wasn't much control over which domains it searched or how recent the results were. Narrowing things down to trusted sources, or excluding stale content, often meant an admin had to reconfigure settings.

What changes

Now agents can pass runtime domain filtering with each call — narrowing results to trusted sources or blocking unwanted domains — without needing an admin to reconfigure anything. Published-date filtering lets you set inclusive from/to date bounds so results stay within a specific, relevant time window.

On the admin side, there's new gateway-level allowlist support and an increased domain cap of up to 100 domains per list, giving tighter overall control. This is aimed squarely at regulated industries, research workflows, and anything that needs strict control over sources and recency.

Dive Deep

The Web Search tool is also expanding beyond its original US East (N. Virginia) availability into Europe (Ireland) and Asia Pacific (Tokyo). Domain and date filters are passed as include/exclude domain lists and a date range directly in each tool call. For the details, check the technical blog on domain and published-date filters and the Amazon Bedrock AgentCore documentation.

Wrap-up

  • Web Search tool now supports domain filtering and published-date filtering
  • Agents can scope sources and time windows per call, with no admin reconfiguration needed
  • Admins get gateway-level allowlists and a domain cap raised to 100 per list
  • Now available in Europe (Ireland) and Asia Pacific (Tokyo), alongside US East

A great fit for regulated industries and research teams that need tight control over what their agents search!
