NoteDiscovery includes a built-in Model Context Protocol (MCP) server, letting AI assistants directly interact with your notes:

What AI Can Do	Example
🔍 Search & Discover	"Find all my notes about Docker deployment"
📝 Create & Edit	"Create a meeting notes template for tomorrow"
📁 Organize	"Move all project notes to the archive folder"
🏷️ Tag & Categorize	"List all notes tagged with #urgent"
📊 Explore Connections	"Show me the knowledge graph of my notes"
✍️ Append Ideas	"Add this thought to my daily journal"

One-line setup for Cursor, Claude Desktop, and other MCP-compatible tools:

{
  "mcpServers": {
    "notediscovery": {
      "command": "docker",
      "args": ["run", "--rm", "-i", "-e", "NOTEDISCOVERY_URL=http://host.docker.internal:8000", "ghcr.io/gamosoft/notediscovery:latest", "python", "-m", "mcp_server"]
    }
  }
}

💡 See MCP.md for complete setup instructions and all available tools.

🚀 Quick Start

Quick Setup

Linux/macOS:

mkdir -p notediscovery/data && cd notediscovery
docker run -d --name notediscovery -p 8000:8000 \
  -v $(pwd)/data:/app/data \
  ghcr.io/gamosoft/notediscovery:latest

Windows (PowerShell):

mkdir notediscovery\data; cd notediscovery
docker run -d --name notediscovery -p 8000:8000 `
  -v ${PWD}/data:/app/data `
  ghcr.io/gamosoft/notediscovery:latest

Open http://localhost:8000 — done! 🎉

💡 Your notes are saved in ./data/. Themes, plugins, locales and default configuration values are included in the image.

Using Docker Compose

Two docker-compose files are provided:

File	Use Case
docker-compose.ghcr.yml	Recommended - Uses pre-built image from GitHub Container Registry
docker-compose.yml	For development - Builds from local source

Option 1: Pre-built image (fastest)

Linux/macOS:

mkdir -p notediscovery/data && cd notediscovery
curl -O https://raw.githubusercontent.com/gamosoft/notediscovery/main/docker-compose.ghcr.yml
docker-compose -f docker-compose.ghcr.yml up -d

Windows (PowerShell):

mkdir notediscovery\data; cd notediscovery
Invoke-WebRequest -Uri https://raw.githubusercontent.com/gamosoft/notediscovery/main/docker-compose.ghcr.yml -OutFile docker-compose.ghcr.yml
docker-compose -f docker-compose.ghcr.yml up -d

Option 2: Build from source (for development)

git clone https://github.com/gamosoft/notediscovery.git
cd notediscovery
docker-compose up -d

See Advanced Docker Setup for volume details.

Running Locally (Without Docker)

For development or if you prefer running directly:

# Clone the repository
git clone https://github.com/gamosoft/notediscovery.git
cd notediscovery

# Install dependencies
pip install -r requirements.txt

# Run the application
python run.py

# Access at http://localhost:8000

Requirements:

• Python 3.8 or higher
• pip (Python package manager)

Using Virtual Environments (Recommended for Arch/Fedora/Ubuntu 23.04+)

Modern Linux distributions enforce PEP 668, which prevents system-wide pip installs. Use a virtual environment instead:

# Clone the repository
git clone https://github.com/gamosoft/notediscovery.git
cd notediscovery

# Create a virtual environment
python -m venv venv

# Activate it (choose your shell):
source venv/bin/activate        # Bash/Zsh (most Linux distros)
source venv/bin/activate.fish   # Fish (CachyOS, etc.)
source venv/bin/activate.csh    # Csh/Tcsh
.\venv\Scripts\activate         # Windows PowerShell

# Install dependencies and run
pip install -r requirements.txt
python run.py

⚠️ Warning

You'll need to activate the virtual environment (source venv/bin/activate) each time you open a new terminal before running the app

Advanced Docker Setup

The image includes bundled config, themes, plugins, and locales. To customize, you must:

1. Map the volume in your docker-compose or docker run command
2. Provide content - the file/folder must exist with valid content (empty = app might break!)

Volume	Purpose	Bundled?
data/	Your notes	❌ You must create
config.yaml	App settings	✅ Yes
themes/	Custom themes	✅ Yes
plugins/	Custom plugins	✅ Yes
locales/	Translations	✅ Yes

🌍 Multiple Languages

NoteDiscovery supports multiple interface languages via JSON locale files in locales/. Open Settings (gear icon) → Language to choose one; the list reflects whatever locales are installed (bundled files, mounts, or your own additions).

To add your own language: See the Contributing Guidelines for instructions on creating translation files.

Docker users: Mount your custom locales folder to add or override translations:

volumes:
  - ./locales:/app/locales  # Custom translations

💡 Pro Tip: If you clone this repository, you can mount the documentation/ folder to view these docs inside the app:

# In your docker-compose.yml
volumes:
  - ./data:/app/data              # Your personal notes
  - ./documentation:/app/data/docs:ro  # Mount docs subfolder inside the data folder (read-only)

Then access them at http://localhost:8000 - the docs will appear as a docs/ folder in the file browser!

🤝 Contributing

Before submitting a pull request, especially for major changes, please:

• Read our Contributing Guidelines
• Open an issue first to discuss major features or significant changes
• Ensure your code follows the project's style and philosophy

🔒 Security Considerations

NoteDiscovery is designed for self-hosted, private use. Please keep these security considerations in mind:

Network Security

• ⚠️ Do NOT expose directly to the internet without additional security measures
• Run behind a reverse proxy (nginx, Caddy) with HTTPS for production use
• Keep it on your local network or use a VPN for remote access
• By default, the app listens on 0.0.0.0:8000 (all network interfaces)

Authentication

• Password protection is DISABLED by default (default password: admin)
• ⚠️ ENABLE AUTHENTICATION AND CHANGE THE DEFAULT PASSWORD if exposing to a network!
• See AUTHENTICATION.md for complete setup instructions
• To disable auth, set authentication.enabled: false in config.yaml
• Perfect for single-user or small team deployments
• For multi-user setups, consider a reverse proxy with OAuth/SSO

Data Privacy

• Your notes are stored as plain text markdown files in the data/ folder
• No data is sent to external services
• Regular backups are recommended

Best Practices

• Run on localhost or a private network only
• Use Docker for isolation and easier security management
• Keep your system and dependencies updated
• Review and audit any plugins you install
• Set appropriate file permissions on the data/ directory

TL;DR: Perfect for personal use on your local machine or home network. Enable built-in password protection if needed, or use a reverse proxy with authentication if exposing to wider networks.
