Developing Interactive MCP Applications with Amazon Bedrock AgentCore

Amazon Web Services has announced that interactive Model Context Protocol applications running rich HTML widgets in AI hosts can be developed using Amazon Bedrock AgentCore.

New Solution for AI Hosts

Users interacting with digital services through artificial intelligence make it necessary for companies to offer rich interfaces without depending on a single platform.

Model Context Protocol extensions and Amazon Bedrock AgentCore provide interactive HTML widgets that run directly within AI clients to meet this need.

Components of the AgentCore Platform

Amazon Bedrock AgentCore is a comprehensive platform designed to build and optimize scalable agents with any framework or model.

While the AgentCore runtime within the platform offers a secure and serverless environment, AgentCore Gateway provides a secure endpoint.

Unicorn Rentals Sample Application

The Unicorn Rentals example enables users to manage unicorn rental transactions with a consistent appearance through AI interfaces.

Requests arriving in natural language are transformed into MCP tool calls and widget HTML resources displayed inside a secure sandboxed iframe.

Technical Infrastructure and Security

This solution utilizes AWS Lambda functions to execute business logic and the Amazon DynamoDB database for data persistence.

The MCP application was built in TypeScript using the official software development kit and is powered by an Express.js server.
