Install Memory Graph in Claude Code, Cursor or VS Code
Runs npx -y mcp-memory-graph on your machine. Read the scan report first; the gateway never runs local packages.

MCP Memory Graph
A memory server for Claude Code and any other MCP client. It gives your AI assistant a permanent, searchable memory that lives in one SQLite file on your machine. Store a decision today, ask about it next month, and the answer comes back. Everything runs locally: the embedding model, the search index, the knowledge graph. No cloud account, no API key, no per-token cost.
License: source-available and free for noncommercial use (PolyForm Noncommercial 1.0.0): personal projects, hobby, study, research, charity, education, and government. Commercial use requires a paid license (COMMERCIAL.md).
Who it's for: developers who want Claude (or Cursor, Codex, any MCP client) to remember decisions across sessions. Solo builders and hobbyists use it free. Teams share a knowledge base over git. And anyone who wants to replace a cloud memory service (mem0, Zep, Letta, Supermemory) with something that runs entirely on their own machine.
What it looks like
Run npx mcp-memory-graph serve and you get a local web dashboard for browsing and searching your memory outside Claude.
Search works by meaning, not keywords. The query below ("how do we handle payments") finds the Stripe, GDPR, and Postgres notes even though none of them contains that phrase — each result carries a confidence score and a match-type badge:
Browse and sort the whole store in one table — scope, type, tags, quality score, and how often each memory has been read:
How it compares
mem0, Zep, Letta, and Supermemory are the usual names for AI memory, and several of them have open-source cores. This one is built around a different default: nothing leaves your machine and there's no infrastructure to run.
Shortened. The full README is on GitHub.
