Build a secure MCP server on AWS with Amazon Bedrock AgentCore

This tutorial details how to build a secure MCP server on AWS using Amazon Bedrock AgentCore. The server is designed to be small and read-only, capable of listing and reading text documents from an Amazon S3 bucket. It employs Amazon Cognito for user authentication and runs as a stateless Streamable HTTP server, leveraging AgentCore Runtime for security, scaling, and observability. The architecture ensures that the server only has permissions for listing buckets and getting objects within a specified prefix, with telemetry sent to Amazon CloudWatch. AI
