Cognitive Memory Python Packages

cognee

Cognee is the open-source AI memory platform for agents. Give your AI agents persistent long-term memory with small models for free

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). Apache-2.0.

yantrikdb-hermes-plugin

YantrikDB memory provider for NousResearch/hermes-agent — self-maintaining memory with benchmarked recall, self-tuning ranking, contradiction tracking, proactive hygiene, and explainable recall.

engram-memory-system

Memory system for AI agents with hybrid retrieval, MCP tooling, and LongMemEval-leading performance.

yantrikdb-mcp

Persistent cognitive memory for AI agents — drop-in MCP server for Claude Code, Cursor, and Windsurf with temporal decay, contradiction detection, a knowledge graph, and autonomous consolidation, backed by the YantrikDB Rust engine.

spector-client

Memory backbone for AI agents. Four-tier store — working, episodic, semantic, procedural — with decay, consolidation, and association graphs. Fused semantic + SIMD-accelerated hybrid recall, in-process MCP, REST/gRPC, and language SDKs.

shodh-memory

Local, LLM-free memory for AI agents. A single offline Rust binary — deterministic and auditable — that learns from use, forgets the irrelevant, and strengthens what matters. No cloud, no API keys.

cortadel

Self-hosted long-term temporal graph memory for AI agents — MCP, REST and a dashboard in one container, with FalkorDB or Memgraph.

cortadel-crewai

Self-hosted long-term temporal graph memory for AI agents — MCP, REST and a dashboard in one container, with FalkorDB or Memgraph.

yantrik-memory

Persistent cognitive memory for AI agents on the YantrikDB engine — hybrid recall, 9 evolving personality traits, bond progression, and a knowledge graph.

cortadel-google-adk

Self-hosted long-term temporal graph memory for AI agents — MCP, REST and a dashboard in one container, with FalkorDB or Memgraph.

yantrikdb-client

Python client SDK for YantrikDB — typed persistent memory over HTTP: remember, recall with retrieval reasons, reflection, contradiction handling, and pluggable embedders.

cortadel-pydantic-ai

Self-hosted long-term temporal graph memory for AI agents — MCP, REST and a dashboard in one container, with FalkorDB or Memgraph.
