Key Points

  • This article demonstrates how to build an AI-powered A/B testing engine using Amazon Bedrock, Amazon ECS, DynamoDB, and the Model Context Protocol (MCP) to tailor variant selection.
  • It argues that incorporating user context allows the system to assign variants more intelligently during experiments, improving traditional A/B testing results.
  • The architecture combines Bedrock for AI, ECS for container orchestration, DynamoDB for data storage, and MCP for model-context exchange.
  • This guide targets engineers and product teams looking to implement AI-enhanced experimentation in their stack.
This post shows you how to build an AI-powered A/B testing engine using Amazon Bedrock, Amazon Elastic Container Service, Amazon DynamoDB, and the Model Context Protocol (MCP). The system improves traditional A/B testing by analyzing user context  to make smarter variant assignment decisions during the experiment.
