MCP Protocol Handler (`mcp_protocol.py`) - JSON-RPC 2.0 implementation - Tool registration & execution - Request/response handling - Error handling với proper error codes ### 2. SSE Handler (`sse_handler.py`) - Server-Sent Events transport - Connection management - Heartbeat mechanism (30s interval) - Concurrent connection support (100 max) ### 3. API Client (`api_client.py`) - Async HTTP client với aiohttp - Connection pooling - Retry logic với tenacity (3 retries) - Parallel execution của 5 APIs với asyncio.gather() ### 4. Natural Language Parser (`nlp_parser.py`) - Regex-based pattern matching - Supports Tiếng Việt và English - Intent detection cho 5 loại checks: - health, users, services, logs, metrics - Timeframe parsing (1h, 24h, 7d, etc.) ### 5. System Check Tool (`system_check.py`) - MCP tool implementation - Natural language query processing - API orchestration - Result formatting ### 6. n8n Integration (`n8n_integration.py`) - Webhook endpoints - Tool execution từ n8n - Response formatting cho n8n workflows --- ## 🔧 Tech Stack ### Backend - **FastAPI** - Modern async web framework - **Python 3.11** - Latest stable Python - **aiohttp** - Async HTTP client - **sse-starlette** - SSE support - **Pydantic** - Data validation - **structlog** - Structured logging ### Monitoring - **Prometheus** - Metrics collection - **Grafana** - Metrics visualization - **prometheus-client** - Python Prometheus integration ### DevOps - **Docker** - Containerization - **Docker Compose** - Multi-container orchestration - **uvicorn** - ASGI server --- ## 📊 APIs Implementation ### 5 ABC System APIs | # | Endpoint | Method | Description | |---|----------|--------|-------------| | 1 | `/api/system/health` | GET | System health status | | 2 | `/api/users/status` | GET | User status list | | 3 | `/api/services/list` | GET | Services list | | 4 | `/api/logs/query` | POST | Query logs với filters | | 5 | `/api/metrics/current` | GET | Current system metrics | Tất cả đều có **Mock implementation** trong `mock-api/server.py` --- ## 🚀 Deployment Options ### 1. Development (với Mock API) ```bash ./demo-start.sh ``` Chạy: Mock API + MCP Server + Prometheus + Grafana ### 2. Production (với real APIs) ```bash docker-compose up -d ``` Chỉ cần set `.env` với real API credentials ### 3. Kubernetes Ready cho K8s deployment: - Health checks: `/health/live`, `/health/ready` - Graceful shutdown - Environment-based configuration - Prometheus metrics --- ## 📈 Monitoring & Metrics ### Prometheus Metrics Exposed ``` mcp_requests_total # Total requests mcp_request_duration_seconds # Request duration mcp_sse_connections_active # Active SSE connections mcp_tool_executions_total # Tool executions ``` ### Grafana Dashboards Login: `admin/admin` tại http://localhost:3000 Create dashboards với queries: ```promql rate(mcp_requests_total[5m]) mcp_sse_connections_active histogram_quantile(0.95, mcp_request_duration_seconds) ``` --- ## 🧪 Testing ### Automated Tests ```bash ./test-demo.sh ``` Tests cover: - ✅ Mock API endpoints (5 APIs) - ✅ MCP Server endpoints (health, info, tools) - ✅ n8n webhooks (Vietnamese & English) - ✅ Natural Language parsing - ✅ System integration ### Manual Testing Xem [DEMO.md](DEMO.md) cho: - SSE connection testing - MCP protocol testing - Natural language queries - n8n webhook testing --- ## 🌍 Natural Language Support ### Supported Languages - 🇻🇳 Tiếng Việt - 🇬🇧 English ### Example Queries **Vietnamese:** ``` "Kiểm tra toàn bộ hệ thống" "Xem logs 24h gần đây" "Tìm lỗi trong logs 1 giờ qua" "Lấy metrics hiện tại" ``` **English:** ``` "Check all systems" "Get logs from last 24 hours" "Search for errors in recent logs" "Get current system metrics" ``` Parser tự động detect intent và gọi đúng APIs. --- ## 🔐 Security Features - ✅ API key authentication - ✅ CORS configuration - ✅ Input validation với Pydantic - ✅ Rate limiting ready - ✅ Non-root Docker user - ✅ Environment-based secrets **Production recommendations:** - Configure CORS properly - Add rate limiting - Use HTTPS (nginx/traefik) - Implement authentication middleware - Use secrets management (Vault, K8s secrets) --- ## 📖 Documentation Files | File | Purpose | |------|---------| | **QUICKSTART.md** | 5-minute setup guide ⭐ | | **DEMO.md** | Comprehensive demo guide | | **README.md** | Full technical documentation | | **PROJECT_SUMMARY.md** | This overview | **Start here:** [QUICKSTART.md](QUICKSTART.md) → [DEMO.md](DEMO.md) → [README.md](README.md) --- ## 🎓 Learning Path ### For Beginners 1. Run `./demo-start.sh` 2. Read [QUICKSTART.md](QUICKSTART.md) 3. Try example commands 4. Explore [DEMO.md](DEMO.md) ### For Developers 1. Read [README.md](README.md) 2. Explore source code in `src/` 3. Understand MCP protocol 4. Customize tools in `src/tools/` ### For DevOps 1. Review Docker setup 2. Check monitoring configuration 3. Read production deployment section 4. Plan K8s deployment --- ## 🛠️ Customization Guide ### Add New Tool 1. Create `src/tools/my_tool.py`: ```python class MyTool: def __init__(self): self.name = "my_tool" self.description = "..." self.input_schema = {...} async def execute(self, params): # Your logic here return result ``` 2. Register in `src/main.py`: ```python my_tool = MyTool() mcp_handler.register_tool( name=my_tool.name, description=my_tool.description, input_schema=my_tool.input_schema, handler=my_tool.execute ) ``` ### Add New API Endpoint Edit `src/api_client.py`: ```python async def my_new_api(self): data = await self._request("GET", "/api/my-endpoint") return data ``` ### Customize NLP Patterns Edit `src/tools/nlp_parser.py`: ```python self.patterns = { "my_intent": [ r"pattern1", r"pattern2", ] } ``` --- ## 📊 Performance Characteristics ### Throughput - **Concurrent API calls:** 5 APIs in parallel - **Connection pooling:** Up to 100 connections - **Worker processes:** 4 (configurable) - **SSE connections:** 100 max (configurable) ### Latency - **Health check:** <10ms - **System check (all 5 APIs):** ~100-300ms (with mocks) - **SSE heartbeat:** Every 30s - **Retry timeout:** Exponential backoff (1s, 2s, 4s) ### Scalability - Horizontal scaling ready - Stateless design - Connection pooling - Async I/O throughout --- ## 🎯 Use Cases ### 1. System Monitoring Monitor multiple systems via natural language queries from n8n workflows. ### 2. Operations Automation Automate system checks, log analysis, and alerting with n8n. ### 3. ChatOps Integration Integrate with Slack/Teams via n8n để control systems with natural language. ### 4. API Aggregation Aggregate multiple APIs into single natural language interface. ### 5. Development Tool Use MCP protocol để integrate with AI tools (Claude, etc.). --- ## 🚦 Project Status - ✅ **Core Features:** Complete - ✅ **Mock API:** Complete - ✅ **Documentation:** Complete - ✅ **Testing:** Automated tests ready - ✅ **Monitoring:** Prometheus + Grafana ready - ✅ **Docker:** Multi-stage build ready - 🟡 **Production deployment:** Needs real API credentials - 🟡 **n8n workflows:** Sample workflows needed - 🟡 **Authentication:** Basic (needs enhancement for production) --- ## 🎉 Quick Win Muốn thấy kết quả ngay? 3 lệnh: ```bash cd mcp-sse-server-python ./demo-start.sh ./test-demo.sh ``` Done!
