# Schema Update Summary
## Date: 2026-01-07
## Changes Made
### Input Schemas (`mcp-input-schemas.json`)
#### ✅ Added Missing Tools
1. **`analyzeMigrationImpactInput`**
- **Description**: Input parameters for analyzing full migration impact combining dependency analysis and source code scanning
- **Required**: `projectPath` (string)
- **Pattern**: Same as other project path inputs
2. **`checkEnvInput`**
- **Description**: Input parameters for checking if an environment variable is defined
- **Required**: `name` (string) - Environment variable name
- **Pattern**: `^[A-Z_][A-Z0-9_]*$` (uppercase letters, numbers, underscores)
#### Updated Tool Mappings
Added to `toolInputs`:
- `analyzeMigrationImpact` → `analyzeMigrationImpactInput`
- `check_env` → `checkEnvInput`
### Output Schemas (`mcp-output-schemas.json`)
#### ✅ Added Premium Features Schema
**New Definition**: `premiumFeatures`
- **Type**: Object (optional in responses)
- **Properties**:
- `recommended` (boolean, required) - Whether premium features are recommended
- `message` (string, required) - Contextual message explaining recommendation
- `features` (array of strings, required) - List of premium features that would help
- `pricingUrl` (string, URI, required) - URL to pricing information
- `estimatedSavings` (string, optional) - Estimated time/effort savings
#### ✅ Added Missing Response Schemas
1. **`migrationImpactResponse`**
- **Status**: success
- **Required Fields**:
- `totalFilesToMigrate`, `totalJavaxImports`, `totalBlockers`
- `totalRecommendations`, `estimatedEffortMinutes`, `complexity`
- `riskScore`, `riskFactors`, `readinessScore`, `readinessMessage`
- `totalFilesScanned`, `totalDependencies`
- **Optional**: `premiumFeatures`
2. **`checkEnvResponse`**
- **Status**: success
- **Required Fields**: `result` (string) - Status message
- **Pattern**: `^(Defined|Missing):.*`
#### ✅ Updated Existing Response Schemas
Added optional `premiumFeatures` field to:
- `blockersResponse` - Appears when blockers are detected
- `recommendationsResponse` - Appears when >5 recommendations or breaking changes
- `migrationPlanResponse` - Appears for complex migrations (>30 min, >5 phases, risk >0.3)
- `migrationImpactResponse` - Appears for high complexity/effort projects
#### Updated Tool Mappings
Added to `toolOutputs`:
- `analyzeMigrationImpact` → `migrationImpactResponse` or `errorResponse`
- `check_env` → `checkEnvResponse` or `errorResponse`
## Schema Validation
✅ **Input Schema**: Valid JSON
✅ **Output Schema**: Valid JSON
## Complete Tool List
### Input Schemas
1. ✅ `analyzeJakartaReadiness` → `analyzeJakartaReadinessInput`
2. ✅ `detectBlockers` → `detectBlockersInput`

2. ✅ `detectBlockers` → `blockersResponse` (with `premiumFeatures`) or `errorResponse`
3. ✅ `recommendVersions` → `recommendationsResponse` (with `premiumFeatures`) or `errorResponse`
4. ✅ `createMigrationPlan` → `migrationPlanResponse` (with `premiumFeatures`) or `errorResponse` or `upgradeRequiredResponse`
5. ✅ `verifyRuntime` → `verificationResponse` or `errorResponse` or `upgradeRequiredResponse`
6. ✅ `analyzeMigrationImpact` → `migrationImpactResponse` (with `premiumFeatures`) or `errorResponse` (NEW)
7. ✅ `check_env` → `checkEnvResponse` or `errorResponse` (NEW)
## Premium Features Integration
The `premiumFeatures` field is now included in response schemas for tools that provide contextual recommendations:
- **`detectBlockers`**: When blockers are found
- **`recommendVersions`**: When >5 recommendations or breaking changes detected
- **`createMigrationPlan`**: When migration is complex (>30 min, >5 phases, risk >0.3)
- **`analyzeMigrationImpact`**: When complexity is HIGH, effort >60 min, >3 blockers, or >20 files
## Next Steps
1. ✅ Schemas updated and validated
2. ⏳ Update API documentation to reflect premium features
3. ⏳ Update example requests/responses file
4. ⏳ Consider generating TypeScript types from schemas
