Memory Graph MCP Server

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.

People who work with agent memory, bi temporal and embeddings and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Memory Graph

before you install - you'll need

Set MCP_AUTH_TOKEN, MEMORY_MCP_TOKEN, MCP_MEMORY_DB_PATH, MCP_MEMORY_MODEL, MCP_MEMORY_DIMENSIONS before connecting.

Claude Code

claude mcp add yonasvalentin-mcp-memory-graph -- npx -y mcp-memory-graph

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "yonasvalentin-mcp-memory-graph": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-memory-graph"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

license no standard license detected - usage rights unclear; check the repo before commercial use

npm package mcp-memory-graph - unscoped; check the name against the project README before installing

registry namespace io.github.YonasValentin is GitHub-verified and matches the repo owner

06 · Memory Graph FAQ

What is Memory Graph?

Is Memory Graph still maintained?

Yes - as of 2026-09-18, its last commit was 2026-08-03 and it shipped 2 releases in the last 90 days. We re-verify nightly.

How do I install Memory Graph?

Run `npx -y mcp-memory-graph`. The README documents 5 environment variables (MCP_AUTH_TOKEN, MEMORY_MCP_TOKEN, MCP_MEMORY_DB_PATH…) to set first. Set MCP_AUTH_TOKEN, MEMORY_MCP_TOKEN, MCP_MEMORY_DB_PATH, MCP_MEMORY_MODEL, MCP_MEMORY_DIMENSIONS before connecting. You can also paste the ready-made client config above.

Does Memory Graph run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
