knowledge-rag vs claude-historian-mcp

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.; claude-historian-mcp: claude-historian-mcp is an MCP server that gives Claude access to your conversation history locally. It provides two tools (search and inspect) with 11 scopes, zero dependencies, and runs completely offline. It helps find past solutions, track file changes, and learn from previous work without burning tokens on idle.
