MCP Memory Service

Universal MCP memory service providing semantic memory search and persistent storage for AI assistants. Works with Claude Desktop, VS Code, Cursor, Continue, and 13+ AI applications with SQLite-vec for fast local search and Cloudflare for global distribution.

🚀 Quick Start (2 minutes)

Universal Installer (Recommended)

# Clone and install with automatic platform detection
git clone https://github.com/doobidoo/mcp-memory-service.git
cd mcp-memory-service
python install.py

Docker (Fastest)

# For MCP protocol (Claude Desktop)
docker-compose up -d

# For HTTP API (Web Dashboard)
docker-compose -f docker-compose.http.yml up -d

Smithery (Claude Desktop)

# Auto-install for Claude Desktop
npx -y @smithery/cli install @doobidoo/mcp-memory-service --client claude

⚠️ First-Time Setup Expectations

On your first run, you'll see some warnings that are completely normal:

"WARNING: Failed to load from cache: No snapshots directory" - The service is checking for cached models (first-time setup)
"WARNING: Using TRANSFORMERS_CACHE is deprecated" - Informational warning, doesn't affect functionality
Model download in progress - The service automatically downloads a ~25MB embedding model (takes 1-2 minutes)

These warnings disappear after the first successful run. The service is working correctly! For details, see our First-Time Setup Guide.

🐍 Python 3.13 Compatibility Note

sqlite-vec may not have pre-built wheels for Python 3.13 yet. If installation fails:

The installer will automatically try multiple installation methods
Consider using Python 3.12 for the smoothest experience: brew install [email protected]
Alternative: Use ChromaDB backend with --storage-backend chromadb
See Troubleshooting Guide for details

🔧 Configuration

Claude Desktop Integration

Add to your Claude Desktop config (~/.claude/config.json):

{
  "mcpServers": {
    "memory": {
      "command": "uv",
      "args": ["--directory", "/path/to/mcp-memory-service", "run", "memory", "server"],
      "env": {
        "MCP_MEMORY_STORAGE_BACKEND": "sqlite_vec"
      }
    }
  }
}

Environment Variables

# Storage backend (sqlite_vec recommended)
export MCP_MEMORY_STORAGE_BACKEND=sqlite_vec

# Enable HTTP API
export MCP_HTTP_ENABLED=true
export MCP_HTTP_PORT=8000

# Security  
export MCP_API_KEY="your-secure-key"
