Semantic Memory Python Packages

yantrikdb

Cognitive memory engine for AI agents — temporal decay, contradiction detection, autonomous consolidation, knowledge graph, ANN recall via HNSW. Embeddable Rust library with Python bindings; powers yantrikdb-server (HTTP gateway, MCP server, openraft cluster). AGPL.

aelfrice

Bayesian memory that learns from feedback for LLM agents

memanto

Memory that AI Agents Love!

mengram-ai

Human-like memory for AI agents — semantic, episodic & procedural. Experience-driven procedures that learn from failures. Free API, Python & JS SDKs, LangChain, CrewAI & OpenClaw integrations.

smartmemo

Semantic memory and caching for LLM agents with classifier-validated equivalence instead of naive cosine thresholds.

mnemory

A self-hosted, two-tier memory system for AI agents and assistants

cashew-brain

Persistent memory for AI agents. Extract once, recall forever.

remembra

Universal memory layer for AI applications. Self-host in minutes. Open source.

mflow-ai

A bio-inspired cognitive memory engine — a new paradigm for Graph RAG.

agent-immune

Adaptive threat intelligence for AI agent security — semantic memory, multi-turn escalation, output scanning, rate limiting, and prompt hardening.

atomicmemory-hermes

Portable semantic memory for AI agents: core engine, TypeScript SDK, framework adapters, MCP server, CLI, and host plugins.

engram-mem

Persistent memory for AI agents. Dual-memory system (episodic vector + semantic graph) with CLI, HTTP, MCP & WebSocket interfaces.

mcp-external-memory

An MCP server that gives LLMs persistent, searchable semantic memory

openparallax-memory

Python wrapper for the OpenParallax memory module

openparallax-shield

4-tier AI security pipeline for autonomous systems

openparallax-sandbox

Python wrapper for the OpenParallax sandbox module

openparallax-audit

Python wrapper for the OpenParallax audit module

openparallax-channels

Python wrapper for the OpenParallax channels module

driftguard-ai

Semantic mistake-memory and guardrail for AI agents. Stops agents from repeating the same failures using causal graphs and semantic matching. Supports MCP, LangGraph, and in-process Python.

hermes-mnemory

A self-hosted, secure, feature-rich memory system for AI agents and assistants. Provides intelligent fact extraction and deduplication, with an artifact store for detailed content.

semantic-recall

Semantic Vector Memory for Coding Agents - Long-term memory system with vector embeddings for fuzzy retrieval

snipara-memory

Open source memory engine for coding agents: semantic recall, session bundles, contradiction handling and a local FastAPI API.
