Build an Insurance AI Agent - Step by Step Enterprise Multi-Agent System using Java and MCP

Learn how to build an Insurance AI Agent using Spring Boot, MCP, and LLMs for claim processing, policy validation, fraud detection, and customer automation.

Introduction

Insurance systems are complex because they involve:

  • Policy validation
  • Claim processing
  • Fraud detection
  • Document verification
  • Customer support

Traditional systems are rule-heavy and slow.

Now we upgrade them using AI:

Insurance AI Agent System


What We Are Building

An AI-powered insurance agent that can:

  • Process insurance claims
  • Validate policy coverage
  • Detect fraudulent claims
  • Summarize claim documents
  • Answer customer queries

Step 1: Create Spring Boot Project

Dependencies:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-validation</artifactId>
    </dependency>
</dependencies>

Step 2: Insurance Request Model

public class InsuranceRequest {
    private String claimId;
    private String customerId;
    private String query;
}

Step 3: Insurance Response Model

public class InsuranceResponse {
    private String result;
}

Step 4: Insurance Controller

@RestController
@RequestMapping("/api/insurance")
public class InsuranceController {

    private final InsuranceAgentService insuranceAgentService;

    public InsuranceController(InsuranceAgentService insuranceAgentService) {
        this.insuranceAgentService = insuranceAgentService;
    }

    @PostMapping("/ask")
    public InsuranceResponse ask(@RequestBody InsuranceRequest request) {
        return insuranceAgentService.process(request);
    }
}

Step 5: Insurance Agent Service

@Service
public class InsuranceAgentService {

    private final PlannerAgent plannerAgent;
    private final ExecutorAgent executorAgent;

    public InsuranceAgentService(PlannerAgent plannerAgent,
                                 ExecutorAgent executorAgent) {
        this.plannerAgent = plannerAgent;
        this.executorAgent = executorAgent;
    }

    public InsuranceResponse process(InsuranceRequest request) {

        // 1. Create execution plan
        String plan = plannerAgent.createPlan(request.getQuery());

        // 2. Execute plan
        String result = executorAgent.execute(plan,
                request.getClaimId(),
                request.getCustomerId());

        // 3. Return response
        InsuranceResponse response = new InsuranceResponse();
        response.setResult(result);

        return response;
    }
}

Step 6: Planner Agent

@Service
public class PlannerAgent {

    public String createPlan(String query) {

        if (query.contains("claim")) {
            return "CLAIM_PROCESSING_PLAN";
        }

        if (query.contains("fraud")) {
            return "FRAUD_DETECTION_PLAN";
        }

        if (query.contains("policy")) {
            return "POLICY_VALIDATION_PLAN";
        }

        return "GENERAL_INSURANCE_PLAN";
    }
}

Step 7: Executor Agent

@Service
public class ExecutorAgent {

    public String execute(String plan,
                          String claimId,
                          String customerId) {

        switch (plan) {

            case "CLAIM_PROCESSING_PLAN":
                return "Claim " + claimId + " processed successfully";

            case "FRAUD_DETECTION_PLAN":
                return "Fraud Score LOW for claim " + claimId;

            case "POLICY_VALIDATION_PLAN":
                return "Policy VALID for customer " + customerId;

            default:
                return "General insurance response generated";
        }
    }
}

Step 8: MCP Integration (Advanced Layer)

Now we upgrade execution using MCP:

ExecutorAgent → MCP Server → Tools + LLM + Compliance Engine

Example 1: Claim Processing

Input:

Process claim CLM123

Flow:

1. Planner selects claim processing plan
2. Executor calls claim tool via MCP
3. LLM validates claim details
4. Response returned

Example 2: Fraud Detection

Input:

Check fraud for claim CLM999

Flow:

1. Planner selects fraud detection plan
2. MCP fraud tool executed
3. Risk score generated
4. Response returned

Example 3: Policy Validation

Input:

Check policy coverage for customer C101

Flow:

1. Planner selects policy validation plan
2. Policy tool executed via MCP
3. Coverage checked
4. Response generated

❌ Data sensitivity
❌ MCP latency overhead
❌ Tool integration complexity


Best Practices

✅ Use MCP for all tool execution
✅ Add compliance layer

✅ Use deterministic tools


Common Mistakes

❌ Mixing compliance logic inside agents
❌ No separation of planner and executor
❌ Hardcoded insurance rules
