AWS details secure Web Search setup for Claude Desktop on Amazon Bedrock
AWS published a walkthrough for connecting Claude Desktop on Amazon Bedrock to Web Search through Amazon Bedrock AgentCore Gateway, with AWS IAM Identity Center, Amazon Cognito, and JWT-based authentication.
Full Report
In a walkthrough published October 2, 2026, AWS explains how Claude Desktop on Amazon Bedrock can invoke Web Search through Amazon Bedrock AgentCore Gateway. The post describes Web Search as a fully managed, Model Context Protocol-compatible capability and demonstrates configuring a Gateway with the Web Search target and managed MCP servers.
The setup uses JWT-based inbound authentication and AWS IAM Identity Center as the Gateway’s authentication source, with Amazon Cognito acting as the federation layer. In the described flow, IAM Identity Center authenticates users through SAML, Cognito issues JWTs, and AgentCore Gateway validates the tokens on each request. AWS says this lets Claude Desktop on Amazon Bedrock invoke Web Search through an enterprise-managed identity flow.
AWS says search query traffic stays within AWS infrastructure, and that Web Search is backed by an Amazon web index spanning tens of billions of documents. The post lists availability in US East (N. Virginia), Europe (Ireland), and Asia Pacific (Tokyo), and instructs users to create the Gateway in one of those Regions.
The post focuses on integrating the existing search capability with Claude Desktop, rather than announcing Web Search for the first time: AWS announced general availability of Web Search on Amazon Bedrock AgentCore on June 17, 2026. For teams using Amazon Bedrock, the walkthrough provides a concrete path for connecting web search, a Gateway, and enterprise identity authentication.
Why This Matters
The walkthrough brings a managed MCP search connector and an enterprise identity flow into one Claude Desktop setup example, and specifies the supported Regions. Those details give teams evaluating web search under existing AWS identity governance practical information about integration and deployment scope.

Jishnu Dasgupta
“Claude Desktop on Amazon Bedrock is limited to the model's knowledge cutoff without web search. In this post, we walk through connecting Claude Desktop to Web Search using Amazon Bedrock AgentCore Gateway, with JWT-based inbound authentication through AWS IAM Identity Center and Amazon Cognito.”
