The setup connects Claude Desktop to an MCP-compatible search service, keeps query traffic within AWS, and uses JWT-based inbound authentication. It shows a concrete way to give an agent current information while managing credentials and network boundaries.

What: AgentCore Gateway connects Claude Desktop to managed, MCP-compatible Web Search for current information.
How: IAM Identity Center authenticates users through SAML; Cognito issues JWTs, which the gateway validates on each request.
Why it matters: The AWS-contained identity and search flow gives engineers current web data without external API keys or queries leaving AWS.
