AWS Adds Managed Web Search to Bedrock AgentCore
Current web knowledge can improve agent usefulness, while introducing untrusted content, source quality, licensing, privacy, and prompt-injection risk.
What happened
AWS announced general availability of Web Search on Amazon Bedrock AgentCore. The managed Gateway tool returns snippets, source URLs, titles, and dates using Amazon search infrastructure and knowledge-graph data. AWS says prompts and retrieval queries remain within the customer’s secured AWS environment rather than being sent to an external search API provider.
Why it matters for enterprise leaders
Grounding is not automatic truth. Teams should define acceptable sources, freshness requirements, citation behavior, privacy limits, and how the agent responds when evidence conflicts or is missing. Web pages are untrusted input and may contain prompt injection. Retrieved content should not be allowed to expand tool permissions or trigger consequential actions without validation and approval.
Questions to take into your next leadership discussion
- Which sources and jurisdictions are acceptable for the use case?
- Can users inspect the exact evidence behind an answer?
- Are retrieved instructions isolated from the agent’s authority and tools?
