cuba-memorys vs mcp-memory-libsql

cuba-memorys: Cuba-Memorys is a Model Context Protocol (MCP) server that gives AI coding assistants long-term persistent memory. It uses a knowledge graph, neuroscience-inspired algorithms like FSRS-6 adaptive decay, Hebbian learning, and dual-strength memory, along with anti-hallucination grounding. The latest version 2.0.0 is a complete Rust rewrite with 12 tools and sub-millisecond performance.; mcp-memory-libsql: mcp-memory-libsql is a high-performance, persistent memory system for the Model Context Protocol (MCP). It uses libSQL to store entities and relations, providing optimized text search with relevance ranking to enhance LLM context efficiency. It supports both local SQLite and remote libSQL databases with secure authentication.
