🚀 Quick Start

Option 1: Docker (Recommended)

The fastest way to get started is using our pre-built Docker image:

# Pull and run the latest image
docker run -d \
  -e [email protected] \
  -e SIMPLENOTE_PASSWORD=your-password \
  -p 8000:8000 \
  docdyhr/simplenote-mcp-server:latest

Or use Docker Compose:

# Clone the repository for docker-compose.yml
git clone https://github.com/docdyhr/simplenote-mcp-server.git
cd simplenote-mcp-server

# Set environment variables
export [email protected]
export SIMPLENOTE_PASSWORD=your-password

# Run with Docker Compose
docker-compose up -d

Option 2: Smithery (One-click install)

Install automatically via Smithery:

npx -y @smithery/cli install @docdyhr/simplenote-mcp-server --client claude

This method automatically configures Claude Desktop with the MCP server.

Option 3: Traditional Python Install

git clone https://github.com/docdyhr/simplenote-mcp-server.git
cd simplenote-mcp-server
pip install -e .
simplenote-mcp-server
