Memory & knowledge MCP servers

Agent-neutral MCP server with persistent memory (SOIL + Postgres KB) and a sandboxed task queue. Manifest-based ACL; works with any stdio MCP client.

🧠 Provide local-first persistent memory for AI coding workflows, indexing notes to deliver relevant context in new sessions.

Universal memory runtime for AI agents

XMemo: user-owned Memory OS for AI agents. Public client (@xmemo/client), MCP distribution, Skills and plugins.

SOAT — open-source infrastructure for production-ready AI agents.

A self-hosted library for the papers and web pages one person reads: hybrid search, a graph whose links cite their sentence, and an MCP interface for agents

Local-first 3-in-1 AI memory layer & MCP server for Claude Code, Codex, Grok, Gemini, VS Code and Cursor. Fuses session history, codebase indexing & concept graphs in SQLite. Enables zero-cloud, privacy-first context & instant recall, supports multi-agent swarms.

Open-source governed, local-first memory control plane for AI agents and teams. arXiv:2608.08253

Point a cross-model AI engineering team at your own codebases. The Agent OS keeps named AI maintainers' identity, memory and review across labs alive between sessions — the Brain Neo.mjs runs on itself. Multi-tenant: onboarding a codebase is a config entry, not a fork.

Local-first AI memory you can see, edit, and override — portable across Claude Code, Codex, Cursor, Windsurf, and other MCP coding tools.

Local-first AI memory you can see, edit, and override — portable across Claude Code, Codex, Cursor, Windsurf, and other MCP coding tools.

An agentic memory database that cuts session tokens by 82–99%. One portable SQLite file — your agent's memory, anywhere.

Memory that learns what works.

Search your files by meaning and fact-check the web, fully offline.

Your First LLM-Wiki Conversation Knowledge Base

Governed graph-native agent memory: knowledge extraction, fusion, hybrid RAG, scoped access tokens. A push for data sovereignty.

Solve it once. From then on, your AI knows. Experience for coding agents over MCP, EU-hosted. 124 MCP tools.

The knowledge compiler. Raw sources in, interlinked wiki out. Inspired by Karpathy's LLM Wiki pattern.

Lens: intelligence for your agent. Safe, secure and cost-effective. A self-hosted, cited knowledge graph and MCP server for your agents, from a Raspberry Pi to the cloud.

Local-first, governed memory and session continuity for AI coding agents, over MCP - verifiable handoffs via signed continuity receipts. Rust, MIT, no telemetry by default.

Cognitive deterministic memory transaction security kernel for agents, that traces backwards to find the root cause and not the lookalike

Transform your codebase into an intelligent knowledge base for AI-powered development with Cursor IDE, Google AntiGravity, and MCP-enabled assistants

Learn while your agent works. A Claude Code plugin that quizzes you on the concepts behind the code it just wrote — local knowledge graph, spaced repetition, optional commit gate.

Engram - file-system-based memory management system for AI agents that grows with you & your teams, across agents, projects, and devices.
