MCP Servers
Connectors that give your AI agent hands — databases, browsers, email, payments, and every service in between.
Memanto MCP
★ 1,600MEMANTO is a memory agent. It remembers, recalls, and answers — so your agents can achieve long-term goals and avoid confusion.
PMB (Personal Memory Brain)
★ 289Local-first persistent memory for AI coding agents over MCP: decisions, lessons and facts persist across sessions via hybrid BM25 + vector + graph retrieval, fully offline, no API keys.
YourMemory
★ 247Persistent memory for AI agents with Ebbinghaus forgetting curve decay, hybrid BM25 + vector + knowledge graph retrieval, temporal reasoning, and a local dashboard. 89.4% Recall@5 on LongMemEval.
Memclaw
★ 240MemClaw — persistent memory for AI agent fleets (OSS) — Trending history, engagement metrics, and Reddit & Hacker News discussions on Trendshift
Mnemory
★ 182A 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.
piia-engram
★ 168Persistent AI memory across tools — remember your preferences, code standards, and decisions across Claude Code, Cursor, Codex, and any MCP tool. Local-first, zero-cloud.
engram
★ 136Local code-knowledge graph + bi-temporal mistakes memory for AI coding agents. Serves a ranked structural packet instead of whole files on read/grep, and surfaces fixes your repo already reverted (mined from git history). Zero cloud, Apache-2.0.
Link
★ 80Local Markdown memory for AI agents
BrainFlow - Shared Team Memory - MCP
★ 48Your company's brain, connected to Claude, ChatGPT, Gemini, Cursor, and VS Code. Turn your team's email history into shared memory that any AI assistant can query with natural language.
Bhived
★ 34Shared memory MCP for AI agents. one agent solves it, every other agent learns.
Agents Remember
★ 25`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).
Memento
★ 21A local-first, LLM-agnostic memory layer for AI assistants
Mori
★ 20Shared memory layer for AI coding agents with dream pipeline distillation, session grounding, and multi-instance coherence.
XMemo
★ 12User-owned memory for AI agents over remote MCP. Save, search, recall, update, and manage scoped memories across Copilot, Claude, ChatGPT, IDEs, and CLIs.
Hindsight-MemPalace
★ 10Self-hosted long-term memory for AI agents: MCP server with hierarchical recall over pgvector.
Myco Brain
★ 7Self-hosted memory and knowledge-graph MCP server for AI agents. TypeScript on Postgres 16 + pgvector, 11 brain_* tools. Runs keyless: full-text and semantic search, ingestion, content-hash dedup, provenance via brain_why, and the knowledge graph all work with no API keys via local Ollama. Apache-2.0.
MarsNMe
★ 6Agent-agnostic persistent memory backend. 13 MCP tools, Supabase + Jina embeddings, multi-profile isolation, semantic recall across sessions.
sessionmem
★ 6Local-first MCP server that gives AI coding assistants persistent session memory. 85.6% token reduction, no cloud.
Krimto
★ 5Open-source team memory layer for AI coding agents. Markdown files in git, a user→team→org hierarchy, one cross-vendor MCP server. Apache-2.0.
Agentic Task System (ats)
★ 5Turns 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.
vault-cortex
★ 5MCP server for Obsidian vaults — plugin-free search, memory, and full vault access for any AI agent.
Dakera
★ 5Self-hosted Rust-based MCP server for AI agent memory — persistent, queryable memory with hybrid search, knowledge graphs, built-in embeddings, and 14 core tools (expandable to 86+ with profile-based tiering).
Vault Cortex
★ 5MCP server for Obsidian vaults — search, memory, link graph, 23 tools, OAuth-protected.
Recall
★ 5Open-source MCP memory server for AI coding agents — durable cross-session memory, per-agent namespaces, ChromaDB-backed, self-hosted.
MCP Memory-mesh
★ 5An MCP server that gives Claude Code persistent memory across sessions (open source, SQLite)
universal-memory
★ 4A vendor-agnostic cognitive persistence layer for AI agents. Eliminate the "repetition tax" by transporting your context, preferences, and history across sessions. Features an auto-adaptation engine that syncs global instructions to ensure operational cohesion and optimize token usage across any LLM or multi-agent workflow.
Brain OS
★ 4Operational memory for AI agents that persists across sessions and tools.
AgenticMind
★ 4Auditable, self-improving knowledge & memory for AI agents over MCP — citation-enforced answers and a replayable why-trace, self-hosted on Postgres.
langmcp
★ 3A MCP server that connects with LangChain Checkpointers, Memory Stores to aid in monitoring and observability during development of AI Applications
Mnemos
★ 3Local-first MCP memory server with no external dependency, source citations and OKF/Markdown KB.
