GRAPH_API_MODERNIZATION_REPORT.md•5.83 kB
# Microsoft Graph API Modernization Report
## Current Status Analysis
### ✅ What's Already Up-to-Date
1. **Base URL**: Using correct `https://graph.microsoft.com/v1.0` endpoint
2. **Authentication**: Using modern MSAL-style scope `https://graph.microsoft.com/.default`
3. **Core Endpoints**: Most endpoints are current and properly structured
4. **Security Alerts**: Using `alerts_v2` which is the current recommended approach
### ⚠️ Areas Requiring Updates
## 1. Legacy Alert API Usage (CRITICAL)
**Issue**: Some code still references the legacy alerts API
**Impact**: The legacy alerts API is deprecated and will be removed by April 2026
### Current Usage:
```typescript
// This is deprecated
client.api('/security/alerts').get()
```
### Should be Updated to:
```typescript
// Use the modern alerts_v2 API
client.api('/security/alerts_v2').get()
```
## 2. Missing Modern Best Practices
### A. Request Optimization
**Current**: Not using `$select` parameter consistently
**Recommendation**: Add selective field querying to improve performance
### B. Error Handling
**Current**: Basic error handling
**Recommendation**: Implement comprehensive error handling with retry logic
### C. Throttling Management
**Current**: No built-in throttling protection
**Recommendation**: Add rate limiting and retry-after handling
## 3. Authentication Modernization
### Current Implementation:
```typescript
scope: "https://graph.microsoft.com/.default",
baseUrl: "https://graph.microsoft.com/v1.0"
```
### Recommended Enhancements:
- Add client-request-id headers for better troubleshooting
- Implement token caching optimization
- Add TLS 1.2+ enforcement
## 4. Endpoint-Specific Updates
### Security API Updates:
- ✅ Using `alerts_v2` (correct)
- ✅ Using `incidents` endpoint (correct)
- ⚠️ Consider migrating from legacy alert references
### Device Management API:
- ✅ Using `deviceManagement/managedDevices` (correct)
- ✅ Using `deviceManagement/deviceCompliancePolicies` (correct)
- ⚠️ Consider adding newer endpoint features
### Intune Policy APIs:
- ✅ Current endpoints are up-to-date
- ⚠️ Could benefit from newer template-based approaches
## 5. New API Features to Consider
### Microsoft 365 Defender Integration:
```typescript
// New advanced hunting capabilities
client.api('/security/runHuntingQuery').post({
query: "DeviceInfo | take 10"
})
```
### Enhanced Incident Management:
```typescript
// Expanded incident details with alerts
client.api('/security/incidents?$expand=alerts').get()
```
### Modern Compliance APIs:
```typescript
// New compliance APIs for better reporting
client.api('/security/compliance/ediscovery').get()
```
## Recommended Action Plan
### Phase 1: Critical Updates (Immediate)
1. Update any remaining legacy alert API calls to `alerts_v2`
2. Add client-request-id headers to all requests
3. Implement proper error handling for 429 (throttling) responses
### Phase 2: Performance Optimization (1-2 weeks)
1. Add `$select` parameters to reduce data transfer
2. Implement response caching where appropriate
3. Add proper pagination handling
### Phase 3: Feature Enhancement (2-4 weeks)
1. Add advanced hunting capabilities for security insights
2. Implement webhook subscriptions for real-time updates
3. Add batch API support for multiple operations
### Phase 4: Future-Proofing (Ongoing)
1. Monitor Microsoft Graph changelog for new features
2. Implement feature flags for beta endpoint testing
3. Add comprehensive logging and monitoring
## Specific Code Updates Needed
### 1. Update Server Configuration
```typescript
// Add client-request-id generation
private getGraphClient(): Client {
const clientRequestId = randomUUID();
return Client.init({
authProvider: this.authProvider,
defaultHeaders: {
'client-request-id': clientRequestId
}
});
}
```
### 2. Add Performance Optimizations
```typescript
// Use selective field querying
const users = await client.api('/users')
.select('id,displayName,userPrincipalName,accountEnabled')
.top(100)
.get();
```
### 3. Implement Retry Logic
```typescript
// Add exponential backoff for throttling
async function graphApiCallWithRetry(client: Client, endpoint: string, maxRetries = 3) {
for (let i = 0; i < maxRetries; i++) {
try {
return await client.api(endpoint).get();
} catch (error) {
if (error.status === 429 && i < maxRetries - 1) {
const retryAfter = error.headers?.['retry-after'] || Math.pow(2, i);
await new Promise(resolve => setTimeout(resolve, retryAfter * 1000));
continue;
}
throw error;
}
}
}
```
## Security Considerations
### 1. Permission Optimization
- Review current permissions for least privilege principle
- Consider using delegated vs application permissions appropriately
- Regular audit of granted permissions
### 2. Data Handling
- Implement proper data retention policies
- Add encryption for cached data
- Follow Microsoft Graph data usage terms
## Monitoring and Compliance
### 1. Add Comprehensive Logging
```typescript
// Log all API calls for monitoring
console.log(`Graph API Call: ${method} ${endpoint}`, {
clientRequestId,
timestamp: new Date().toISOString(),
userId: context.userId
});
```
### 2. Performance Metrics
- Track API response times
- Monitor error rates
- Watch for throttling incidents
## Conclusion
Your MCP server is largely using current Microsoft Graph APIs, but there are several opportunities for improvement:
1. **Critical**: Ensure no legacy alert API usage remains
2. **Important**: Add performance optimizations and better error handling
3. **Beneficial**: Implement new features like advanced hunting and improved incident management
The modernization will improve reliability, performance, and future-proofing of your MCP server.
