Build ChatGPT Apps with MCP Servers and AWS Infrastructure
Industries Blog
This article explains how to build ChatGPT Apps for retail using AWS infrastructure and Model Context Protocol (MCP) servers, featuring a coffee store example.
- ChatGPT Apps allow customers to shop, get recommendations, and purchase without leaving the conversation
- MCP Servers must be hosted externally; AWS provides ideal scalable infrastructure
- Example workflow: natural language query → product search → details → narrowed recommendations → cart addition
- AWS architecture uses API Gateway, Lambda, Cognito, Bedrock, and OpenSearch Serverless
- Hybrid search combines keyword and semantic search for natural language product discovery
- DynamoDB manages shopping cart state; S3/CloudFront serve product images
- MCP server investments are reusable across multiple AI shopping channels
- GitHub repository available with deployable reference architecture
AWS enables retailers to build conversational shopping experiences by providing secure, scalable infrastructure for hosting MCP servers that power ChatGPT Apps.
