knowledge-rag vs MCP-Nest

knowledge-rag: Knowledge RAG is a fully local, zero-cloud document retrieval system that lets Claude Code search your PDFs, markdown, code, and notebooks natively. It indexes up to 1800+ files in under 3 minutes, using hybrid search (BM25 + semantic vectors + cross-encoder reranking) via 12 MCP tools. Everything runs locally via ONNX, no Docker, Ollama, or API keys required.; MCP-Nest: This NestJS module simplifies exposing AI tools, resources, and prompts using the Model Context Protocol (MCP). It integrates seamlessly with NestJS's dependency injection to build complex, enterprise-ready MCP servers.
