Building healthcare AI agents with open-source AWS HealthLake MCP server

This article introduces an open-source AWS HealthLake MCP Server that enables AI agents to interact with healthcare data using natural language, eliminating the need for deep FHIR and AWS SDK expertise.

• MCP Server provides natural language interfaces to AWS HealthLake FHIR resources for healthcare data operations
• Supports complete CRUDS functionality with advanced search capabilities and chained parameters
• Automatic datastore discovery eliminates manual configuration overhead
• Read-only mode available for production environments and compliance requirements
• Built-in AWS SigV4 authentication with automatic credential handling
• Enables patient summarization with specialty-specific context and real-time clinical information
• Automates prior authorization processes by analyzing approval patterns and payor policies
• Integrates with AWS IAM and CloudTrail for security and audit compliance
• Works with Amazon Bedrock AgentCore and AgentCore Gateway for enterprise healthcare integration

The HealthLake MCP Server reduces technical barriers to FHIR resource management, enabling healthcare professionals to build AI-powered applications that improve patient care and streamline clinical workflows.
