Microsoft 365 Core MCP Server

# Enhanced Intune Policy Tools Integration This document describes the successful integration of enhanced Intune policy creation tools into the M365 Core MCP server. ## Overview The integration adds powerful enhanced Intune policy creation capabilities alongside the existing tools, providing advanced validation, templates, and platform-specific schemas. ## Available Tools ### Original Tools (Maintained) 1. **`createIntunePolicy`** - Basic Intune policy creation 2. **`create_intune_policy`** - Schema-driven policy creation ### Enhanced Tools (New) 3. **`enhanced_create_intune_policy`** - Advanced policy creation with comprehensive validation ## Enhanced Features ### ✅ Platform-Specific Validation - **Windows**: Supports Configuration, Compliance, Security, Update, AppProtection, and EndpointSecurity policies - **macOS**: Supports Configuration, Compliance, Security, Update, and AppProtection policies - Discriminated union schemas ensure correct settings for each platform/policy type combination ### ✅ Advanced Schema Validation - Required field validation - Type-specific field validation (e.g., password length, OS versions) - Base64 validation for macOS .mobileconfig files - Assignment target validation ### ✅ Built-in Policy Templates #### Windows Templates: - `basicSecurity`: Standard security configuration - `strictSecurity`: High-security configuration - `windowsUpdate`: Update management configuration #### macOS Templates: - `basicSecurity`: Standard security configuration - `strictSecurity`: High-security configuration ### ✅ Automatic Default Application - Applies platform and policy-type specific defaults - Ensures policies have sensible baseline configurations - User settings override defaults intelligently ### ✅ Comprehensive Error Handling - Detailed validation error messages - Policy creation examples in error responses - Contextual warnings for best practices ### ✅ Assignment Validation - Validates group IDs, collection IDs, and filter IDs - Ensures proper assignment intent (apply/remove) - Validates assignment settings structure ## Usage Examples ### Basic Enhanced Policy Creation ```json { "platform": "windows", "policyType": "Compliance", "displayName": "Corporate Windows Compliance", "description": "Standard compliance policy for corporate Windows devices", "useTemplate": "basicSecurity" } ``` ### Advanced macOS Configuration ```json { "platform": "macos", "policyType": "Configuration", "displayName": "macOS Security Configuration", "description": "Custom security configuration for macOS devices", "settings": { "policyType": "Configuration", "settings": { "customConfiguration": { "payloadFileName": "security.mobileconfig", "payload": "PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4..." } } }, "assignments": [ { "target": { "groupId": "aaaaaaaa-0000-1111-2222-bbbbbbbbbbbb" }, "intent": "apply" } ] } ``` ### Windows Update Policy with Template ```json { "platform": "windows", "policyType": "Update", "displayName": "Managed Windows Updates", "description": "Controlled update deployment for production systems", "useTemplate": "windowsUpdate" } ``` ## Implementation Details ### File Structure ``` src/ ├── tool-definitions-intune-enhanced.ts # Enhanced tool schemas ├── handlers/ │ └── intune-handler-enhanced.ts # Enhanced policy handler └── validators/ └── intune-policy-validator.ts # Validation logic and templates ``` ### Key Components 1. **Enhanced Schemas**: Discriminated union schemas that enforce platform-specific settings 2. **Validation Engine**: Comprehensive validation with helpful error messages 3. **Template System**: Pre-configured policy templates for common scenarios 4. **Default System**: Intelligent default application based on platform and policy type 5. **Assignment Validation**: Ensures proper assignment configuration ### Backwards Compatibility The integration maintains full backwards compatibility: - All existing tools continue to work unchanged - No breaking changes to existing functionality - Enhanced tools use distinct names to avoid conflicts ## Testing The integration includes comprehensive tests: - `test-enhanced-intune-tools.mjs`: Validates all enhanced features - `test-schema-simple.mjs`: Tests schema validation - `test-integration.mjs`: Ensures server integration works All tests pass successfully, confirming the integration is stable and functional. ## Benefits 1. **Improved Accuracy**: Platform-specific validation prevents invalid policy configurations 2. **Faster Development**: Templates provide quick starting points for common scenarios 3. **Better UX**: Detailed error messages with examples help users fix issues quickly 4. **Enterprise Ready**: Advanced validation ensures policies meet compliance requirements 5. **Maintainable**: Clear separation between original and enhanced tools ## Future Enhancements The enhanced tools provide a foundation for future improvements: - Additional policy templates - More granular validation rules - Policy comparison and diff tools - Bulk policy operations - Policy inheritance and composition This integration successfully brings enterprise-grade Intune policy management to the M365 Core MCP server while maintaining simplicity and backwards compatibility.
