🧠 Persistent memory MCP for AI agents — Knowledge graph + Hebbian learning + Anti-hallucination. 12 tools, 1 dependency, zero manual setup.

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.

    Knowledge graph memory with Hebbian learning for AI agents is a sophisticated approach.

    Parker GarciaMay 11, 2026

    Associative memory that strengthens with use mirrors how memory works in practice.

    Peyton MartinezApr 21, 2026

    Good for agents doing long-term research or project work where associations matter.

    Persistent across sessions, the knowledge graph grows more useful over time.
