Best Memory MCP Servers

Local-first agent memory: a plain-Markdown Obsidian vault is the source of truth, with a rebuildable DuckDB index for hybrid BM25 + vector + graph recall.

Persistent memory and semantic search for AI coding assistants across sessions

Give your agent a memory: shared, cited, tenant-isolated knowledge-graph memory for any MCP host. Grounded answers from a local-first June endpoint — abstains rather than guesses.

Agent-native knowledge server. Serves docs to AI agents over SSH and MCP with identity-scoped views, governed writing, and structured metadata. Single binary, zero config.

Decentralized persistent memory for AI agents — encrypted vault storage built on Walrus and Sui.

Persistent memory for AI assistants and coding agents across ChatGPT, Claude, Cursor, and other MCP-compatible tools.

@memofs/mcp-server lets AI coding agents securely read and write MemoFS memory through standard Model Context Protocol tools.

Your portable AI memory vault — memories, skills & configs, shared across every AI tool.

Local Work Model for AI agents that learns from real outcomes.

Adaptive MCP memory system for AI applications. Learns which retrieval strategies work for your data, scores results using cognitive science models, builds a knowledge graph automatically, and validates every parameter change against real query history before adopting it. Patent pending.

Local stdio MCP server for coding agents: shared troubleshooting memory, agent-to-agent help posts, replies, and a unified inbox. Quick start: npx -y agent-only-mcp

Turns your task manager into agent memory: hybrid (RRF) retrieval over TickTick or an Obsidian vault via an adapter contract. MCP server + CLI, no vector DB to maintain.

Auditable, self-improving knowledge & memory for AI agents over MCP — citation-enforced answers and a replayable why-trace, self-hosted on Postgres.

MCP-native memory layer for Claude Code, Cursor, Cline, Continue, and 16 other AI tools. Hybrid search (BM25 + pgvector + graph), self-hosted on Supabase + Vercel, 100% MIT, no paywall.

Paid remote MCP endpoint for persistent AI agent memory, site analytics, pricing, checkout status, and search-readiness operations.

Governed persistent memory for AI agents.

`Agents Remember` is a Drift-aware repository memory for coding agents in complex codebases. Captures what code can't say on its own! Retrieves memory by path, semantic search, and relationship (code-graph).

Persistent memory for Claude, Cursor, and ChatGPT. Save, organize, and search your context across every AI tool.

AI coach for Claude with persistent training memory: log workouts, get a program, track progress across sessions.

Chat forgets your workouts. AIm remembers them for Claude and ChatGPT: sets, weights, 1RM, volume.

Long-term memory for AI assistants. Your AI remembers everything, forever.

Atlaso is a memory layer for AI tools — connect once and it automatically recalls the context that matters across Claude Code, Cursor, Codex, and every AI tool you use.

One shared, versioned memory for your AI agents across Claude Code, Cursor, Kiro and Grok, with a source on every answer and full history.

One shared context every AI tool your team uses reads and writes over MCP, so Claude Code, Cursor and ChatGPT stay current together.
