What io.github.YonasValentin/mcp-memory-graph does

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.

README

MCP Memory Graph

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.

	MCP Memory Graph	Typical hosted memory service
Where it runs	One SQLite file on your machine	A managed cloud service (some also self-host)
Embeddings	Local model in Node (MiniLM), no API key	Usually a cloud embedding API
Cost per token	$0 — nothing is metered	Usage-based, or a server you operate
Extra infrastructure	None	Often Postgres/pgvector, Redis, or a Python service
Claude Code integration	First-class: hooks auto-capture and recall	Manual wiring
Benchmarks	Committed corpus + runner, reproducible locally	Mostly self-reported

The trade-off is honest: a single-process SQLite server tops out in the low hundreds of thousands of vectors (see Limitations), and a hosted service will scale past that without you thinking about it. If you're a solo developer or a small
