Setup snapshot

git clone https://github.com/chrisribe/simple-memory-mcp.git
  1. 1

    Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Full README

🧠 Simple Memory MCP Server

npm version License: MIT TypeScript

Give your AI assistant persistent memory across sessions.

The problem: AI assistants forget everything when you start a new conversation. Your preferences, project context, decisions - all gone.

The solution: Simple Memory lets AI store and retrieve information that persists forever. Local SQLite database, zero cloud, sub-millisecond fast.

Why not RAG? RAG systems need vector databases, embeddings, chunking strategies, and ongoing maintenance. Simple Memory is just keyword search in SQLite - no ML infrastructure, no API costs, works offline. Perfect for personal knowledge that doesn't need semantic similarity.

How It Works

You: "Remember that I prefer TypeScript over JavaScript and use 4-space indentation"

AI: stores this automatically

...days later, new session...

You: "Help me set up a new project"

AI: searches memory, finds your preferences → Sets up TypeScript with 4-space indentation

The AI handles storage and retrieval automatically. You just chat naturally.

Simple by design: Keyword search, not semantic. Local SQLite, not cloud. Zero setup, not configuration hell. If you need vector embeddings or team collaboration, see alternatives.

<details> <summary><strong>📖 End-to-End Example</strong></summary>

Session 1 (January):

You: "I'm using PostgreSQL with TypeScript. Decided on Prisma ORM after 
      evaluating TypeORM - better type inference and migrations."

AI: → stores automatically with tags [tech-stack, database, decision]

Session 2 (3 weeks later):

You: "Setting up a new microservice, what database setup should I use?"

AI: → searches memories, finds your PostgreSQL + Prisma decision
   "Based on your previous work, you standardized on PostgreSQL with Prisma 
    ORM. You chose it over TypeORM for the better type inference..."

What got stored:

{
  "content": "Tech stack decision: PostgreSQL + Prisma ORM. Chose over TypeORM for better type inference and cleaner migrations.",
  "tags": ["tech-stack", "database", "decision"],
  "relevance": 0.92  // BM25 score when searching "database setup"
}
</details>

✨ Features

  • 🧠 Persistent Memory - Survives across sessions, restarts, forever
  • 🔍 Full-Text Search - Find memories by keyword, tags, or content
  • 🏷️ Smart Tagging - Organize memories with tags
  • 💾 Automatic Backups - Optional sync to OneDrive/Dropbox
  • 📦 Zero Config - Works out of the box
  • 🚀 Fast - Sub-millisecond queries, 2,000-10,000 ops/sec

🚀 Quick Start

Configure MCP Client

Claude Desktop (claude_desktop_config.json):

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

VS Code (.vscode/mcp.json):

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

Restart your MCP client - that's it! No install needed.

💡 Best Experience: Works best with Claude Sonnet in Agent Mode for optimal auto-capture.

Auto-Configure VS Code & Claude Desktop

npx -y simple-memory-mcp setup

This automatically configures all detected installations.

Optional: Install CLI

For command-line usage (search, stats, export/import):

npm install -g simple-memory-mcp
simple-memory setup  # auto-configure VS Code & Claude

For Contributors

git clone https://github.com/chrisribe/simple-memory-mcp.git
cd simple-memory-mcp
npm run setup  # installs, builds, links, and configures

That's it! The AI assistant can now remember information across conversations.

💻 CLI Commands

# Setup - auto-configure VS Code and Claude Desktop
simple-memory setup

# Search memories
simple-memory search --query "typescript" --limit 5
simple-memory search --tags "project,work"

# Store a memory
simple-memory store --content "Remember this" --tags "note"

# Other operations
simple-memory get --hash "abc123..."
simple-memory delete --hash "abc123..."
simple-memory stats

# Export/import
simple-memory export-memory --output backup.json
simple-memory import-memory --input backup.json

Run simple-memory --help for all options.

🛠️ MCP Tools

The AI uses these tools automatically - you don't need to call them directly.

| Tool | Purpose | |------|---------| | memory-graphql | Store, search, update, delete memories | | export-memory | Backup memories to JSON file | | import-memory | Restore memories from JSON file |

<details> <summary>GraphQL Schema (for developers)</summary> 
type Memory { hash, content, title, preview, tags, createdAt, relevance }
type StoreResult { success, hash, error }
type UpdateResult { success, hash, error }
type DeleteResult { success, hash, deletedCount, error }

type Query {
  memories(query: String, tags: [String], limit: Int): [Memory!]!
  memory(hash: String!): Memory
  related(hash: String!, limit: Int): [Memory!]!
  stats: Stats!
}
type Mutation {
  store(content: String!, tags: [String]): StoreResult!
  update(hash: String!, content: String!, tags: [String]): UpdateResult!
  delete(hash: String, tag: String): DeleteResult!
}

Note: Mutation results return minimal data (hash/success). To get full memory fields (title, tags, createdAt), query: { memory(hash: "...") { ... } }

</details>

⚙️ Configuration

Zero config default: ~/.simple-memory/memory.db

Custom database location:

{
  "mcpServers": {
    "simple-memory": {
      "command": "npx",
      "args": ["-y", "simple-memory-mcp"],
      "env": {
        "MEMORY_DB": "/path/to/memory.db"
      }
    }
  }
}

With automatic backups:

{
  "env": {
    "MEMORY_BACKUP_PATH": "/path/to/OneDrive/backups",
    "MEMORY_BACKUP_INTERVAL": "180"
  }
}

📖 Full configuration guide: docs/configuration.md

  • Environment variables reference
  • Backup strategies
  • Cloud storage best practices
  • HTTP transport setup
  • Multiple database instances
