MCP Weather & Accruals Server

# 📦 SUMMARY OF CHANGES - v0.2.0 (Accruals Support) ## 🎯 Objective Completed Successfully extended the remote FastAPI (on 192.168.0.137:8000) with full support for managing accrual data (Ozon commission tracking). The local Deepseek client can now query accrual statistics and create new records through the remote API. --- ## 📝 Changes Made ### Modified Files #### `fastapi_udalennii/app/models.py` ```python # ✅ ADDED: Accruals table definition accruals = Table( "accruals", metadata, # 18 columns including id, id_accrual, accrual_date, service_group, # accrual_type, sales_platform, total_amount_rub, and more... ) ``` - Added SQLAlchemy Table for storing accrual records - Uses Numeric type for monetary values (precision 15,2) - Includes unique constraint on id_accrual #### `fastapi_udalennii/app/schemas.py` ```python # ✅ ADDED: Three new Pydantic models class AccrualCreate(BaseModel) - for creating new accruals class Accrual(AccrualCreate) - for reading accruals (with ID) class AccrualStats(BaseModel) - for statistics responses ``` #### `fastapi_udalennii/app/crud.py` ```python # ✅ ADDED: Three new async CRUD functions async def create_accrual(accrual: AccrualCreate) async def get_accruals(skip, limit, service_group, sales_platform, accrual_type) async def get_accrual_stats(service_group, sales_platform, accrual_type) ``` #### `fastapi_udalennii/app/main.py` ```python # ✅ REWRITTEN: Complete refresh with accruals support # ADDED: 4 new endpoints POST /accruals/ - Create new accrual GET /accruals/ - List accruals with filtering GET /stats/summary - Overall statistics GET /stats/accruals - Filtered statistics # PRESERVED: Existing user endpoints POST /users/ GET /users/ GET /health GET / ``` ### New Files #### `fastapi_udalennii/alembic/versions/0002_create_accruals_table.py` -

[x] Models created (SQLAlchemy) - [x] Schemas created (Pydantic) - [x] CRUD operations implemented - [x] API endpoints implemented - [x] Alembic migration created - [x] Error handling added - [x] Documentation written - [x] Test script created - [x] Quick deployment guide created - [x] Syntax checked - [x] Integration with Deepseek verified --- ## 📊 Integration with Deepseek Client The local `deepseek_client.py` automatically integrates through: ```python # In modules/deepseek_api.py async def query_accruals_api(endpoint: str, params: dict = None, method: str = "GET", data: dict = None): """Query the remote Accruals API""" # Uses ACCRUALS_API_URL from environment ``` **Example user interaction:** ``` 👤 You: Show me accrual statistics for Ozon 🤖 Deepseek: [queries GET /stats/accruals?sales_platform=Ozon] Total: 42 accruals, 123,456.78 RUB average 2,939.45 RUB ``` --- ## 🔒 Security Notes 1. Database credentials in `.env` are not version-controlled (included in .gitignore) 2. API endpoints have basic duplicate ID checks 3. All numeric fields use appropriate types (Numeric for money) 4. SQL injection protected through SQLAlchemy ORM 5. CORS not configured (add if needed for cross-origin requests) --- ## 📈 Performance Considerations 1. **Indexing**: Consider adding indexes on: - `id_accrual` (already indexed via UNIQUE) - `accrual_date` - `sales_platform` - `service_group` 2. **Query Optimization**: Statistics calculations done in Python (could be moved to database) 3. **Pagination**: Implemented via `skip` and `limit` parameters --- ## 🔄 Migration Guide From v0.1.0 to v0.2.0: 1. **Code**: Update `fastapi_udalennii/` folder 2. **Database**: Run `alembic upgrade head` 3. **Restart**: Restart FastAPI service 4. **Test**: Verify endpoints via curl or test_accruals_api.py **Rollback** (if needed): ```bash alembic downgrade -1 # Roll back 1 migration ``` --- ## ✨ Key Features Added ✅ **Accrual CRUD** - Create, Read, Filter accrual records ✅ **Statistics** - Summary and filtered statistics with aggregation ✅ **Async/await** - Fully asynchronous database operations ✅ **Input Validation** - Pydantic models for request validation ✅ **Error Handling** - Duplicate ID detection, database errors ✅ **Database Migrations** - Alembic migrations for schema management ✅ **Documentation** - OpenAPI/Swagger docs auto-generated ✅ **Filtering** - Support for service_group, sales_platform, accrual_type ✅ **Pagination** - skip/limit parameters for list endpoints --- ## 📚 Documentation Files | File | Purpose | | ----------------------------------- | ----------------------------- | | `README.md` | Main project documentation | | `DEPLOYMENT_INSTRUCTIONS.md` | Detailed deployment guide | | `QUICK_DEPLOYMENT.md` | One-liner deployment commands | | `ACCRUALS_IMPLEMENTATION_REPORT.md` | Implementation details | | `REFACTORING_SUMMARY.md` | Architecture overview | | `test_accruals_api.py` | API testing script | --- ## ✅ Testing Instructions ### Local Testing ```bash python3 test_accruals_api.py ``` ### Remote Testing ```bash # Health check curl http://192.168.0.137:8000/health # Create test accrual curl -X POST http://192.168.0.137:8000/accruals/ \ -H "Content-Type: application/json" \ -d '{"id_accrual":"TEST_001","accrual_date":"2025-12-08","service_group":"Test","accrual_type":"Test","sales_platform":"Ozon","total_amount_rub":100}' # Get statistics curl http://192.168.0.137:8000/stats/summary # View API docs open http://192.168.0.137:8000/docs ``` --- ## 🎯 Next Steps Optional enhancements: 1. Add authentication (JWT tokens) 2. Add rate limiting 3. Add CORS configuration 4. Add caching for statistics 5. Add database indexes for optimization 6. Add more detailed logging 7. Add webhooks for new accruals 8. Add data export (CSV/Excel) --- **Version:** 0.2.0 **Date:** December 9, 2025 **Status:** ✅ READY FOR DEPLOYMENT
