🔒 Security

Handling Sensitive Data

⚠️ IMPORTANT: Never commit sensitive files to the repository:

• token.pickle
• client_secrets.json
• .env files
• Any other credential files

These files are automatically ignored by .gitignore, but if you accidentally commit them:

1. Remove them from git tracking:

git rm --cached token.pickle
git rm --cached client_secrets.json

2. Revoke and regenerate any exposed credentials
3. Update your local .env file with new credentials
4. Never share or expose these files publicly

Best Practices

1. Always use environment variables for sensitive data
2. Keep credentials in .env file (already in .gitignore)
3. Regularly rotate API keys and tokens
4. Use OAuth 2.0 for authentication
5. Monitor GitHub's secret scanning alerts

🚀 Quick Start

Prerequisites

1. Installing Python

macOS:

# Using Homebrew (recommended)
brew install python@3.11

# Verify installation
python3 --version  # Should show Python 3.11.x

Linux (Ubuntu/Debian):

# Update package list
sudo apt update

# Install Python
sudo apt install python3.11 python3.11-venv

# Verify installation
python3 --version  # Should show Python 3.11.x

Windows:

1. Download Python installer from python.org
2. Run the installer
3. Check "Add Python to PATH" during installation
4. Open Command Prompt and verify:

python --version  # Should show Python 3.11.x

2. Installing uv

macOS/Linux:

# Install uv using the official installer
curl -LsSf https://astral.sh/uv/install.sh | sh

# Verify installation
uv --version

Windows (PowerShell):

# Install uv using the official installer
(Invoke-WebRequest -Uri "https://astral.sh/uv/install.ps1" -UseBasicParsing).Content | pwsh -Command -

# Verify installation
uv --version

Alternative Installation Methods:

Using pip (if you prefer):

# Install uv using pip
pip install uv

# Verify installation
uv --version

3. Setting Up Google Cloud Credentials

1. Create a Google Cloud Project:

   Copy

   # Go to Google Cloud Console
   https://console.cloud.google.com
   
   # Click on "Select a Project" at the top
   # Click "New Project"
   # Name it (e.g., "youtube-mcp-server")
   # Click "Create"

2. Enable YouTube Data API:

   Copy

   # In the Google Cloud Console:
   # 1. Go to "APIs & Services" > "Library"
   # 2. Search for "YouTube Data API v3"
   # 3. Click "Enable"

3. Create OAuth 2.0 Credentials:

   Copy

   # In the Google Cloud Console:
   # 1. Go to "APIs & Services" > "Credentials"
   # 2. Click "Create Credentials" > "OAuth client ID"
   # 3. Select "Desktop app" as application type
   # 4. Name it (e.g., "YouTube MCP Client")
   # 5. Click "Create"

4. Download and Store Credentials:

   Copy

   # 1. After creating credentials, click "Download JSON"
   # 2. Rename the downloaded file to 'credentials.json'
   # 3. Move it to your project root:
   mv ~/Downloads/client_secret_*.json ./credentials.json
   
   # Verify the file exists and has correct permissions
   ls -l credentials.json  # Should show -rw------- (readable only by you)

5. First-time Authentication:

   Copy

   # Run the server once to authenticate
   python mcp_videos.py
   
   # This will:
   # 1. Open your browser
   # 2. Ask you to sign in to Google
   # 3. Grant permissions to the application
   # 4. Create a token.pickle file (automatically ignored by git)

⚠️ Important Security Notes:

• Never commit credentials.json or token.pickle to git
• Keep your credentials secure and don't share them
• If credentials are compromised:
  1. Go to Google Cloud Console
  2. Delete the compromised credentials
  3. Create new credentials
  4. Update your local credentials.json

Installation

1. Clone the repository:

git clone https://github.com/yourusername/youtube-mcp-server.git
cd youtube-mcp-server

2. Create and activate a virtual environment:

# Create virtual environment
python -m venv .venv

# Activate virtual environment
# On macOS/Linux:
source .venv/bin/activate
# On Windows (Command Prompt):
.venv\Scripts\activate
# On Windows (PowerShell):
.venv\Scripts\Activate.ps1

3. Install dependencies using uv:

# Install project in editable mode
uv pip install -e .

# If you encounter any SSL errors on macOS, you might need to:
export SSL_CERT_FILE=/etc/ssl/cert.pem

4. Set up YouTube API credentials:
   • Go to Google Cloud Console
   • Create a new project
   • Enable YouTube Data API v3
   • Create credentials (OAuth 2.0 Client ID)
   • Download the credentials and save as client_secrets.json

Development Setup

For development, you might want to install additional tools:

# Install development dependencies
uv pip install -e ".[dev]"

# Install pre-commit hooks
pre-commit install

Configuration

1. Create a .env file in the project root:

# Required environment variables
YOUTUBE_API_KEY=your_api_key_here

# Optional configuration
YOUTUBE_API_QUOTA_LIMIT=10000  # Daily quota limit
YOUTUBE_API_REGION=US          # Default region

2. Verify your setup:

# Check if credentials are properly set up
ls -l credentials.json  # Should exist and be readable
ls -l .env             # Should exist and be readable
ls -l token.pickle     # Should exist after first authentication
