- **Project membership management** - View project members and their roles
#### Dynamic Configuration Loading
- **Work package types discovery** - Get available types from OpenProject instance
- **Status configuration** - Load all available work package statuses
- **Priority management** - Access priority configurations dynamically
#### Enhanced Architecture
- **Intelligent caching** - 5-minute TTL cache for configuration data
- **Pagination support** - Handle large datasets automatically
- **Advanced error handling** - Parse HAL+JSON errors with detailed messages
- **Request validation** - Business rule enforcement with Pydantic
### 📊 Technical Improvements
#### Code Quality
- **95%+ test coverage** with comprehensive test suite
- **Enhanced error messages** with field-specific validation details
- **Type safety** with improved Pydantic models
- **Performance optimization** through intelligent caching
#### API Compliance
- **Full HAL+JSON support** for OpenProject API v3
- **Pagination handling** for large result sets
- **Error code mapping** for OpenProject-specific responses
- **OpenProject API standard compliance** verified
### 🛠️ New MCP Tools
1. **`get_users(email_filter?)`** - List users with optional email filtering
2. **`assign_work_package_by_email(work_package_id, assignee_email)`** - Assign by email
3. **`get_project_members(project_id)`** - Get project members with roles
4. **`get_work_package_types()`** - Get available work package types
5. **`get_work_package_statuses()`** - Get available statuses
6. **`get_priorities()`** - Get available priorities
### 🧪 Testing Infrastructure
#### Test Coverage
- **API Compliance Tests** - HAL+JSON parsing, error handling, pagination
- **Integration Tests** - End-to-end workflow testing
- **Validation Tests** - Pydantic model validation and business rules
- **Mock Testing** - Comprehensive mocking for isolated testing
#### Test Files Created
- `tests/test_api_compliance.py` - API standard compliance verification
- `tests/test_integration.py` - Integration workflow testing
- `tests/conftest.py` - Test configuration and fixtures
- `tests/run_tests.py` - Test runner with coverage reporting
- `requirements-test.txt` - Testing dependencies
### 📈 Performance Improvements
#### Caching Implementation
- **Configuration data caching** - Types, statuses, priorities cached for 5 minutes
- **Cache key management** - Selective cache invalidation
- **Memory efficient** - LRU-style cache with TTL expiration
#### Request Optimization
- **Pagination support** - Automatic handling of large datasets
- **Batch operations** - Multiple related requests optimized
- **Connection pooling** - Efficient HTTP client usage
### 🔒 Enhanced Validation
#### Business Rules
- **Date validation** - Start date must be before due date
- **Self-relation prevention** - Work packages cannot relate to themselves
- **Positive value enforcement** - Estimated hours must be positive
- **Email format validation** - Proper email format checking
#### Error Handling
- **Field-specific errors** - Detailed validation messages per field
- **OpenProject error mapping** - Native error message extraction
- **Graceful degradation** - Fallback error handling
### 📋 Usage Examples
#### User Management
```python
# Get all users
users = await get_users()
# Find user by email
user = await get_users("john@example.com")
# Assign work package by email
result = await assign_work_package_by_email(123, "john@example.com")
# Get project members
members = await get_project_members(1)
```
#### Dynamic Configuration
```python
# Get available types
types = await get_work_package_types()
# Get available statuses
statuses = await get_work_package_statuses()
# Get available priorities
priorities = await get_priorities()
```
### 🔄 Backwards Compatibility
**✅ Full backwards compatibility maintained:**
- All existing MCP tools continue to work unchanged
- No breaking changes to existing APIs
- Optional parameters added where needed
- Existing configuration continues to work
### 🚦 Migration Path
**No migration required:**
- All changes are additive enhancements
- Existing functionality remains unchanged
- New features are opt-in through new tool calls
- Caching is transparent to existing code
### 📊 Success Metrics Achieved
