📚 MCP-RAG
MCP-RAG system built with the Model Context Protocol (MCP) that handles large files (up to 200MB) using intelligent chunking strategies, multi-format document support, and enterprise-grade reliability.
🌟 Features
📄 Multi-Format Document Support
- PDF: Intelligent page-by-page processing with table detection
- DOCX: Paragraph and table extraction with formatting preservation
- Excel: Sheet-aware processing with column context (.xlsx/.xls)
- CSV: Smart row batching with header preservation
- PPTX: Support for PPTX
- IMAGE: Suppport for jpeg , png , webp , gif etc and OCR
🚀 Large File Processing
- Adaptive chunking: Different strategies based on file size
- Memory management: Streaming processing for 50MB+ files
- Progress tracking: Real-time progress indicators
- Timeout handling: Graceful handling of long-running operations
🧠 Advanced RAG Capabilities
- Semantic search: Vector similarity with confidence scores
- Cross-document queries: Search across multiple documents simultaneously
- Source attribution: Citations with similarity scores
- Hybrid retrieval: Combine semantic and keyword search
🔌 Model Context Protocol (MCP) Integration
- Universal tool interface: Standardized AI-to-tool communication
- Auto-discovery: LangChain agents automatically find and use tools
- Secure communication: Built-in permission controls
- Extensible architecture: Easy to add new document processors
🏢 Enterprise Ready
- Custom LLM endpoints: Support for any OpenAI-compatible API
- Vector database options: ChromaDB (local) + Milvus (production)
- Batch processing: Handles API rate limits and batch size constraints
- Error recovery: Retry logic and graceful degradation
