MCP Server (22 Tools)

Full Model Context Protocol server for AI agent integration:

• Notes: create, read, update, delete, search, duplicate
• Notebooks: create, list, update, delete
• Labels: create, list, update, delete, assign to notes
• System: health check, stats, bulk operations
• Modes: stdio (Claude Desktop) or SSE (N8N, HTTP)

Authentication & Security

• NextAuth.js with credentials provider
• Email/password authentication
• Password reset via SMTP
• Role-based access (USER/ADMIN)

Quick Start (Local)

Prerequisites: Node.js 22, PostgreSQL 16

cd memento-note
npm install

# Configure database
cp .env.example .env
# Edit .env with your PostgreSQL connection string

# Setup database
npx prisma migrate dev --name init

# Start development server
npm run dev

Open http://localhost:3000

Docker Deployment

Using Docker Compose (root)

# Configure environment
cp .env.docker.example .env.docker
# Edit .env.docker with your settings

# Start all services (PostgreSQL + app + MCP server)
docker compose up -d

# Check status
docker compose ps

Services:

• memento-note - Web app on port 3000
• postgres - PostgreSQL 16 on port 5432 (configurable via POSTGRES_PORT)
• mcp-server - MCP server on port 3001 (SSE mode)
• ollama - Optional local LLM (use profile --profile ollama)

Standalone (memento-note only)

cd memento-note
chmod +x deploy.sh
./deploy.sh build
./deploy.sh start

Useful Commands

docker compose logs -f memento-note   # View logs
docker compose exec memento-note sh   # Shell access
./deploy.sh backup                    # PostgreSQL backup (pg_dump)
./deploy.sh update                    # Pull, rebuild, restart

MCP Server

The MCP server enables AI agents to interact with your notes programmatically.

Configuration

Set in .env.docker:

MCP_MODE=stdio    # or "sse" for HTTP/N8N
MCP_PORT=3001     # SSE mode port

N8N Integration

Configure an MCP tool node in N8N pointing to:

http://mcp-server:3001/sse

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "memento": {
      "command": "node",
      "args": ["path/to/mcp-server/index.js"],
      "env": {
        "DATABASE_URL": "postgresql://memento:memento@localhost:5432/memento"
      }
    }
  }
}
