Building a Medical AI Assistant with Spring Boot: A Practical Guide to MCP Server Integration

Overview: The Path to Intelligent Healthcare Systems

In the era of rapid digital healthcare evolution, traditional medical systems are undergoing intelligent transformation. This guide provides a comprehensive walkthrough for building an MCP-compliant AI service core using Spring Boot, enabling natural language-driven medical information management. The open-source solution is available on GitHub (Project Repository) with one-click Docker deployment support.

Technical Architecture Breakdown

Core Component Relationships

Key Technical Standards

• MCP Protocol: Standardized communication specification (Model Context Protocol)
• SSE Transport: Real-time event streaming via HTTP long connections
• Tool Annotation: @Tool marked service methods

Three-Step Implementation Guide

Step 1: Data Layer Modeling

@Entity
@Table(uniqueConstraints = @UniqueConstraint(columnNames = {"first_name", "last_name", "date_of_birth"}))
public class Patient {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String firstName;  // Patient's given name
    private String lastName;   // Patient's surname
    private LocalDate dateOfBirth; // Date of birth
}

Design Principles:

1. Unique constraints prevent duplicate registrations
2. In-memory database enables millisecond response
3. Medical record associations (one-to-many relationships)

Step 2: Service Layer Exposure

@Tool(name="Find_Patient_by_Last_Name", description="Retrieve patients by surname")
public List<Patient> findByLastName(String lastName){
    return repository.findByLastName(lastName); 
}

Configuration Standards:

• Method naming follows verb+noun structure
• Description fields clarify input/output parameters
• Comprehensive exception handling mechanisms

Step 3: Communication Layer Setup

spring:
  ai:
    mcp:
      server:
        name: spring-clinic-mcp-server
        sse-endpoint: /sse

Parameter Specifications:

• name: Service instance identifier
• sse-endpoint: Event stream access path
• version: Interface version control

Real-World Application Scenarios

Scenario 1: Voice-Activated Record Retrieval

User Command: “Show treatment records for Li family patients in May 2024”
System Workflow:

1. Parse surname and date range parameters
2. Execute findByLastNameAndDateRange() method
3. Automatically format results into readable tables

Scenario 2: Intelligent Record Updates

User Command: “Record Zhang San’s blood glucose level as 7.8mmol/L on May 20”
Execution Process:

1. Extract patient ID, test item, and value
2. Trigger createMedicalRecord() method
3. Perform medication compatibility checks

Deployment & Validation Guide

Docker Environment Setup

# Build image
./gradlew clean build
docker build --tag=spring-mcp-server:latest .

# Run container
docker run -p 8080:8080 spring-mcp-server:latest

Client Connection Verification

1. Install Node.js environment
2. Clone SeekChat repository

git clone https://github.com/seekrays/seekchat.git
cd seekchat
npm install
npm run dev

3. Configure MCP Server address
   

Critical Issue Resolution

Data Consistency Assurance

Performance Optimization Strategies

1. Caching Mechanism: Frequent query caching
2. Batch Processing: Multi-condition combined queries
3. Index Optimization: Composite indexes on key fields

Frequently Asked Questions (FAQ)

Q1: How is medical data privacy ensured?

A: Three-layer protection system:

• HTTPS transmission encryption
• Sensitive field masking
• Operational audit logging

Q2: What types of natural language commands are supported?

A: Currently supports two command types:

1. Data queries: “Show…”/”Find…”
2. Data operations: “Add…”/”Update…”

Q3: What are the local deployment requirements?

A: Basic requirements:

• JDK 21+
• Docker Desktop
• 4GB available memory
• Modern SSE-compatible browser
