Memory MCP Server

Overview

Memory MCP is a reference implementation in the modelcontextprotocol/servers repo. It stores entities, relations, and observations in a local graph so agents can remember across runs. Tiny, opinionated, easy to extend into a real long-term memory layer.

Best for

Best for
Anyone who wants 'the agent remembers me' without a heavy memory stack

Use cases

• Persist user facts across Claude or Cursor sessions
• Build an assistant that actually remembers project context
• Bootstrap an agent memory layer without picking a vector DB on day one
• Template for your own memory schema

How to use

Install

npx -y @modelcontextprotocol/server-memory

Tested with

Claude Desktop

Example client config

[object Object]

Notes

Why it matters

Persistent memory is the difference between an agent that helps and an assistant that knows you. The reference MCP is the cheapest way to feel that shift.

How teams use it in production

Start with the reference. Fork into a server backed by Postgres or Supabase once you have enough writes to outgrow the local store.

What to watch

The convergence between MCP memory servers, vector stores, and per-user graphs is the real long-term memory architecture question for agents.
