Step-by-Step Implementation

​

Step 1: Connect Data Sources

1. Connect Expense System (Expense reports, receipts)
2. Connect HR System (Employee data, policies)
3. Connect Approval System (Approvals, workflows)

​

Step 2: Create Expense Views

CREATE VIEW expense_anomalies AS
SELECT 
  e.expense_id,
  e.employee_id,
  e.category,
  e.amount,
  e.submission_date,
  -- Anomaly indicators
  CASE WHEN e.amount > AVG(e.amount) OVER (PARTITION BY e.category) * 2 THEN 1 ELSE 0 END as high_amount_flag,
  CASE WHEN e.amount < AVG(e.amount) OVER (PARTITION BY e.category) * 0.1 THEN 1 ELSE 0 END as low_amount_flag,
  CASE WHEN e.category NOT IN (SELECT category FROM policies.allowed_categories) THEN 1 ELSE 0 END as policy_violation_flag
FROM expenses.expenses e;

​

Step 3: Create MCP Tools

• review_expense(expense_id: string)

• identify_anomalies(days_back: number, min_amount: number)

• check_compliance(expense_id: string, policy_version: string)

• generate_audit_report(period: string, include_anomalies: boolean)

​

Example Agent Interactions

• Total Expenses: $125K
• Anomalies Found: 12
• High Risk: 3 expenses ($15K total)
  • Employee #456: $8K meal expense (policy limit:$500)
  • Employee #789: $5K travel (no receipts)
  • Employee #123: $2K duplicate submission
• Recommendation: Flag for manual review”

​

Outcomes

• Review Speed: 85% faster
• Anomaly Detection: 90% accuracy
• Compliance: 95% policy compliance
• Fraud Detection: 60% earlier detection
