Agent memory
Reviewed resources in Agent memory. 450 resources listed.
MCP Memory Keeper
github.comA Model Context Protocol server that gives Claude Code and other AI coding assistants persistent memory across sessions, storing project history, decisions and progress in a local, SQLite-backed store shared across parallel sessions.
memex
memra.vercel.appA Zettelkasten-based persistent memory system for AI coding agents that stores atomic, linked knowledge cards as plain markdown, shared across Claude Code, Cursor, Codex and other MCP clients.
MFS
zilliztech.github.ioA context harness for AI agents that presents code, memory, docs, chats and databases from many sources as one searchable, browsable file-like tree.
EchoVault
github.comA local-first memory tool for coding agents that stores decisions, bug fixes and project context as markdown, indexed with full-text search and optional semantic search.
Mnemo Cortex
projectsparks.aiAn MCP server that gives AI agents persistent memory: semantic search and recall over stored memories, confidence-scored verified facts, and encrypted sync between machines.
Prism Coder
synalux.aiAn MCP server that gives Claude, Cursor and other AI coding tools persistent session memory across restarts, routing simple tool calls to a bundled local model fleet instead of the cloud and reporting the tokens saved.
HyperspaceDB
yar.inkA high-performance vector database using 1-bit quantization and hyperbolic geometry to model hierarchical data, aimed at autonomous agents and robotics rather than static document search.
GBase
github.comAn agent framework that gives an AI agent long-term memory with active recall, a self-evolution cycle that rewrites its own prompts after failures, and multi-agent quality gates before code ships.
A folder of Markdown, YAML and bash you drop into a git project to add cross-session memory and delivery governance to AI coding tools, splitting a discovery step that plans from a delivery step that executes in isolation.
engraph
github.comA local knowledge-graph and hybrid-search server for Obsidian vaults that exposes an MCP server, an HTTP REST API and ChatGPT Actions so AI agents can search, read and edit notes.
YantrikDB
yantrikdb.comA cognitive memory database for AI agents that actively manages what it stores, consolidating duplicates, detecting contradictions, and fading out stale memories through temporal decay.
pi-memory
github.comA persistent memory extension for the Pi coding agent, keeping durable facts, a daily log, and a scratchpad as plain Markdown files, with optional semantic search across everything remembered.
OWASP Agent Memory Guard
owasp.orgAn official OWASP project that screens an AI agent's memory writes against a policy, blocking prompt-injection-style attempts to poison persistent memory that survive a context reset.
Mainline
mainline.shA tool that lets AI coding agents save engineering intent and decisions to Git alongside the code, so a later agent can read why a path was tried and abandoned, catch a conflict with another agent's in-progress work, or see the constraints behind risky code before editing it.
context-engine
github.comA pure-Python library that decides what an LLM actually sees from retrieved documents: retrieval, re-ranking, memory decay and token-budget enforcement in one pipeline.
Ambient Context
ambientcontext.appA macOS menu bar app that quietly logs what you read and work on all day into local Markdown files, then turns that record into a cited knowledge base and daily summary for an AI assistant.
hipocampus
github.comA drop-in proactive memory harness for AI agents that builds a compaction tree over past sessions and combines it with keyword or vector search, so an agent can surface relevant past context that nobody explicitly asked about.
MEM-KB
2023782whl.github.ioA self-hosted knowledge workspace for teams that organizes documents, notes, and a knowledge graph for retrieval-augmented question answering, with built-in RAG evaluation and nightly self-consolidation.
the Veil
gary23w.github.ioAn open-source desktop app that runs a team of specialist AI coding agents on your machine, carrying project memory between sessions, using a built-in model, Ollama or any OpenAI-compatible endpoint.
Memory Sidecar
github.comAn installable, agent-agnostic external memory system for Claude Code, Codex, Cursor, Hermes and similar agents, archiving sessions and building long-term recall without modifying the agent itself.
ClawMem
github.comAn on-device memory layer that gives Claude Code, OpenClaw and Hermes agents retrieval-augmented recall of past sessions, through hooks, an MCP server and a shared local SQLite vault.
graphmind
getgraphmind.comA local-first code-intelligence tool that turns a codebase into a queryable knowledge graph for AI assistants, combining an AST-based structural graph, semantic embeddings, and persistent cross-session memory to cut token usage versus raw search.
MineEcho
github.comA source-available, local-first Memory OS for personal AI assistants that remembers user preferences and past work, learns from imported knowledge through a linked wiki and graph, routes to skills and external AI apps, and compresses context to spend fewer tokens.
MemGraphRAG
arxiv.orgA memory-enhanced GraphRAG framework accepted at a 2026 data-mining conference that organizes retrieval into three connected layers, an abstract schema, extracted facts, and source passages, with conflict detection between facts and their supporting evidence.
