Memory & knowledge MCP servers

Your AI Coding Assistant's Long-Term Memory

这是一个功能强大且易用的MySQL数据库MCP(Model Context Protocol)服务器,让你的AI助手可以安全地进行完整的数据库操作,支持多数据库连接管理、增删改查、事务管理和智能回滚功能。

MCP server for Obsidian — access your vault from any AI agent, even when your machine is off. Powered by Self-hosted LiveSync.

Team knowledge evaporates daily — pairing sessions, debugging context, architectural rationale lost to Slack. Distillery captures it at the point of creation, connects it into a living graph, and surfaces it conversationally. It monitors feeds, tracks what matters to your projects, and alerts you be

The open retrieval layer for AI coding agents. Indexes code, docs, legal, research, data — 22 parsers (incl. EPUB, DOCX, ODT), FTS5 + semantic search, knowledge graph. Serves surgical context via MCP. Open source, local, free.

Your fleet's smart notepad — one that learns. Shared memory your agents write to and get back at the right moment, plus a ledger showing what the work cost and which chores keep getting done by hand. Self-hosted, MIT.

Open Source Implementation of Karpathy's LLM Wiki. Upload documents, connect your Claude account via MCP, and have it write your wiki !

The memory your AI should have had from the start. Automatic capture, automatic recall, 100% local. One SQLite file, zero cloud. Works with Claude Code, Claude CLI, Cursor, Codex CLI, Gemini CLI.

Local code search combining BM25, vector similarity, and cross-encoder reranking. Parses 60+ languages with tree-sitter, runs entirely offline, and returns structured results with file paths, line ranges, and symbol metadata. Built in Rust.

Multi-repo semantic code search MCP server in Rust — hybrid vector + BM25 retrieval, tree-sitter AST chunking, fully offline. For OpenCode, Claude Code, Cursor, and any MCP client.

Ontology-based MCP server that analyzes database schemas (PostgreSQL, Snowflake, ClickHouse, Dremio) and generates RDF/OWL ontologies with SQL mappings for fan-trap-free Text-to-SQL.

Plain, structured thinking while you work. It's free, open, and local-first.

Model Context Protocol server for AFFiNE. Connect AI assistants to AFFiNE workspaces, documents, databases, and collaboration APIs over stdio or HTTP.

Search, archive, and recall your AI conversations. ChatGPT, Claude, Gemini, Grok, Kimi. Local-first, MIT licensed.

Local-first shared memory and task coordination for AI coding agents. One Go binary, MCP server, markdown files you own. Hooks for Claude Code and Codex CLI (and their desktop apps).

Production nutrition-tracking PWA (React, Supabase) built and operated inside Claude Code: production RAG pipeline, hybrid semantic search (pgvector), self-built remote MCP server (OAuth 2.1 + PKCE, RLS-enforced), three-model AI fallback chain, and an LLM eval harness gating every release.

The local-first LLM Wiki: open-source knowledge graph builder, RAG knowledge base, and agent memory store. Built on Andrej Karpathy's pattern. An Obsidian alternative for personal knowledge management, AI second brain, and durable Claude Code / Codex / OpenClaw memory.

Ontology-based MCP server that analyzes database schemas (PostgreSQL, Snowflake, ClickHouse, Dremio) and generates RDF/OWL ontologies with SQL mappings for fan-trap-free Text-to-SQL.

MCP server for life-science knowledge graphs

Munnin — an agent identity server: persistent memory for AI agents (identity, reasoning, episodic, knowledge) plus the procedures for tending it, served over MCP. Apache-2.0, runs locally in 5 minutes.

Self-hosted mem0 MCP server for Claude Code. Run a complete memory server against self-hosted Qdrant + Neo4j + Ollama while using Claude as the main LLM.

Anti-poisoning memory store for agents: provenance, versioning, quarantine gate

Local-first AI PKM for coding conversations: import Claude Code/Cursor/Codex, distill notes, semantic search, tag graph, MCP memory.

Verified memory for AI coding agents. Every memory carries evidence and is re-verified on every pull — stale beliefs get flagged, not retrieved. MCP + CLI.
