MCP Servers

Agentic Task System (ats)

★ 10

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.

Obsidian MCP Server

★ 9

Self-hosted MCP server for Obsidian: semantic + full-text search, wikilink graph, note CRUD, OAuth, and a self-describing vault guide.

sessionmem

★ 8

Local-first MCP server that gives AI coding assistants persistent session memory. 85.6% token reduction, no cloud.

Dakera

★ 8

Self-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).

MarsNMe

★ 7

Agent-agnostic persistent memory backend. 13 MCP tools, Supabase + Jina embeddings, multi-profile isolation, semantic recall across sessions.

Nauro

★ 7

Persistent project context for AI coding agents: captures decisions, rationale, and rejected paths so agents stay consistent across Claude, Cursor, Codex, and any MCP enabled platform.

Myco Brain

★ 7

Self-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.

Brain OS

★ 6

Operational memory for AI agents that persists across sessions and tools.

MCP Memory-mesh

★ 6

An MCP server that gives Claude Code persistent memory across sessions (open source, SQLite)

Krimto

★ 6

Open-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.

AccInt

★ 6

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

Recall

★ 6

Open-source MCP memory server for AI coding agents — durable cross-session memory, per-agent namespaces, ChromaDB-backed, self-hosted.

LAIN-mcp

★ 6

Rust MCP server that gives AI coding agents architectural awareness — persistent knowledge graph, blast radius analysis, co-change detection via git, and local semantic search. No API keys, runs entirely on-premise.

MemPlato

★ 6

Remember everything. Stored on your device, not theirs.

Universal Memory (UMem)

★ 6

A 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.

trilium-mcp

★ 5

Read and write a self-hosted TriliumNext knowledge base over its ETAPI. Ten tools: create/get/update/append/delete notes, full search, labels and relations.

Adaptive Recall

★ 4

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.

Lorekeeper

★ 4

Self-improving MCP memory server for AI agents. One command, no cloud, no config. Hybrid search, feedback loop quality system, dashboard UI, auto-linking knowledge graph. Gets better the more you use it.

TokenKnows

★ 4

Capture AI coding sessions (Claude Code / Codex / Cursor) and distill them into weekly reports, ADRs and a knowledge graph — self-hosted.

AgenticMind

★ 4

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

Rekindle

★ 4

A local MCP continuity engine that helps Claude Code pick up the thread across sessions.

Statewave

★ 3

MCP server for Statewave, an open-source memory runtime for AI agents. Provides persistent memory, context retrieval, and memory compilation through the Model Context Protocol.

Cosmos

★ 3

your ai exocortex

langmcp

★ 3

A MCP server that connects with LangChain Checkpointers, Memory Stores to aid in monitoring and observability during development of AI Applications

Citadel

★ 3

Local-first encrypted memory for AI agents with cryptographic forgetting

Memxus

★ 2

One memory. Every AI. Nothing to install. Memxus works across Claude, ChatGPT, Cursor and Slack — and any app your team uses that needs to remember (Notion, Linear/Jira, Gmail, Salesforce/HubSpot, Intercom, Zendesk, Google Drive, Confluence, GitHub). No extension, no local setup, no repeated context. Save once. Remember everywhere.

MemHeaven

★ 2

Self-hosted remote MCP memory server for ChatGPT and AI agents.

AgentMemory

★ 2

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.

Presence

★ 2

Presence: cross-session memory and a verification gate for Claude Code

structured.sh

★ 2

Self-hosted MCP server for persistent agent memory. Define typed schemas, write records, and query with SQL via DuckDB against Parquet files on disk.
