Memory MCP Server: Give Claude a Brain That Remembers Across Conversations

AI agents forget everything when you close the chat. Memory MCP Server fixes that — it's a local knowledge graph that lets Claude, Cursor, and other AI tools store and recall facts across sessions. Named entities, relationships, observations, and context all persist on your machine. No cloud, no external APIs. Just persistent memory.

What It Does

The Memory MCP Server bridges a fundamental gap in AI agent workflows: continuity. Without it, every conversation starts from scratch. With it, your AI agent can accumulate knowledge.

The server lets you:

• Store entities: People, projects, databases, configs—anything Claude needs to remember
• Create relationships: Link entities together ("Alice works on payments project")
• Add observations: Notes, metadata, and contextual details tied to entities
• Query naturally: Claude can ask questions and get answers from the knowledge graph
• Persist across restarts: Your memory survives session closures and agent restarts
• Delete or update: Remove stale info or correct mistakes as they come up

This is a fundamentally different UX from context windows or prompt engineering. Instead of jamming everything into the token limit, Claude actively maintains a knowledge base it can read and update on demand.

How to Install

Install via npm:

npx -y @modelcontextprotocol/server-memory

Then add to your claude_desktop_config.json:

{
  "mcpServers": {
    "memory-mcp-server": {
      "command": "npx -y @modelcontextprotocol/server-memory"
    }
  }
}

Restart Claude Desktop and the memory server is live.

Real-World Use Cases

• Maintain project context: "Remember that our production database is on AWS us-east-1 with read replicas in eu-west-1" — Claude pulls this up without you restating it every session.
• Store team metadata: Note that Alice leads the payments project, Bob owns DevOps, and the frontend team uses SvelteKit. Claude now knows your org structure.
• Preserve configurations and secrets: Store API keys, environment variables, and local setup instructions that Claude can access when you ask it to deploy or debug.

Memory MCP Server is the official, most-trusted implementation of persistent memory in the MCP ecosystem. It's free, open-source, and runs entirely locally.
