Amazon adds Web Search to Claude Desktop via AgentCore
Amazon Bedrock’s AgentCore now lets enterprises connect Claude Desktop to a secure, on-premises web search tool. The Web Search capability, powered by an AWS-managed index of tens of billions of documents, bridges Claude’s knowledge cutoff by fetching real-time data like pricing, documentation, or weather without external APIs or leaving the AWS boundary.
Key points
- Web Search fetches real-time data from AWS’s index of tens of billions of documents without external APIs
- Authentication uses AWS IAM Identity Center + Cognito for JWT-based SSO, keeping queries within AWS infrastructure
- Integration requires Python 3.10+, Boto3, and Claude Desktop configured with AgentCore Gateway in supported regions
The setup requires AgentCore Gateway with JWT-based authentication, tied to AWS IAM Identity Center for SSO. Users authenticate via SAML, and Amazon Cognito federates identities to issue JWTs for gateway validation. This approach avoids third-party credentials and aligns with existing enterprise identity governance. The integration is available in us-east-1, eu-west-1, and ap-northeast-1 regions. AWS provides step-by-step Python scripts and CLI commands for configuration, including linking Claude Desktop’s connectors to the gateway.
The feature is aimed at organizations using AWS for secure, compliant AI workflows. Testing shows Claude automatically invokes the tool for queries needing live data, with user approval required per request.
