# Amazon Bedrock Adds Web Search As A Server-Side Grounding Tool

## Retrieval answer

The product delta is operational consolidation: models can request web grounding inside Bedrock without teams orchestrating a separate search vendor and API path, while enterprise access and audit controls remain in AWS.

AWS made Web Search generally available on Amazon Bedrock as a built-in server-side tool for foundation-model grounding.

A model using the Bedrock Responses API can decide to invoke web search, receive current results, and incorporate them into its response without the application separately integrating and orchestrating a third-party search API. Access can be governed with IAM and activity recorded through CloudTrail.

The architectural gain is fewer moving parts in the request path: one provider contract for model execution, tool invocation, permissions, and audit. The trade-off is concentration. Search quality, retrieval policy, availability, and model behavior now sit behind the same platform boundary and should be evaluated as separate failure modes.

Teams should test citation behavior, disallowed-domain controls, prompt-injection resistance, latency, and cost before treating the tool as a general research layer. Built-in grounding removes integration code; it does not remove source verification.
