Installation

Clone this repository:

git clone https://github.com/zoharbabin/kaltura-mcp.git
cd kaltura-mcp

Install dependencies:

pip install -e .

Usage Modes

This server supports two deployment modes:

🔧 Local MCP Server (Stdio Mode)

Best for: Personal use, direct Claude Desktop integration, development

🌐 Remote MCP Server (HTTP/SSE Mode)

Best for: Hosted services, multiple users, production deployments

Local MCP Server Setup (Claude Desktop)

Step 1: Install Package

pip install kaltura-mcp

Step 2: Setup Environment Configuration

🔒 Secure Method (Recommended): Use the interactive setup script:

# Navigate to your project directory
cd /path/to/kaltura-mcp

# Run the interactive setup
python setup_env.py

The script will guide you through: 1. Choosing between stdio (local) or remote mode 2. Securely entering your Kaltura credentials 3. Generating a .env file with proper permissions (600) 4. Providing the exact Claude Desktop configuration

📋 Manual Method: Copy and edit the example file:

# Copy the example file
cp .env.example .env

# Edit with your credentials
# - For stdio mode: Only fill in KALTURA_* variables
# - For remote mode: Fill in JWT_SECRET_KEY, OAUTH_*, and SERVER_* variables
nano .env

# Set secure permissions
chmod 600 .env

Step 3: Get Your Kaltura Credentials

You'll need these credentials from your Kaltura account:

Service URL: Your Kaltura server URL (usually https://cdnapisec.kaltura.com)
Partner ID: Your numeric partner ID (found in KMC → Settings → Integration Settings)
Admin Secret: Your API admin secret key (found in KMC → Settings → Integration Settings)
User ID: Your Kaltura user ID (usually your email or admin)

Step 4: Configure Claude Desktop

Open your Claude Desktop configuration file:

macOS: ~/Library/Application\ Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

🔒 Secure Configuration (credentials in .env file):

{
  "mcpServers": {
    "kaltura": {
      "command": "/full/path/to/kaltura-mcp"
    }
  }
}

Important Notes: - Replace /full/path/to/kaltura-mcp with the actual path to your kaltura-mcp command (find it with which kaltura-mcp) - The .env file is automatically loaded from the project directory by the server - The setup_env.py script will automatically detect and provide the correct command path

Step 5: Restart Claude Desktop

After saving the configuration file, restart Claude Desktop completely for the changes to take effect.

Step 6: Test the Integration

In Claude Desktop, try asking: - "Search for recent Kaltura videos" - "List my Kaltura categories" - "Find videos about [topic] in my Kaltura account"

Troubleshooting Local Setup

Issue: kaltura-mcp command not found - Solution: Make sure you installed with pip install kaltura-mcp and the command is in your PATH

Issue: "Error: Missing required environment variables" - Solution: 1. Check that .env file exists in your project directory 2. Verify file permissions: ls -la .env (should show -rw-------) 3. Ensure all required Kaltura credentials are set in .env file

Issue: "Invalid credentials" or "Authentication failed" - Solution: 1. Verify your credentials in Kaltura KMC → Settings → Integration Settings 2. Check .env file for typos or extra spaces 3. Run python setup_env.py to recreate the configuration

Issue: Claude Desktop doesn't show the MCP server - Solution: 1. Check the config file syntax with a JSON validator 2. Verify the command path is correct (use which kaltura-mcp) 3. Restart Claude Desktop completely 4. Check Claude Desktop logs for error messages

Issue: ".env file not found" error - Solution: 1. Run python setup_env.py from your project directory 2. Ensure the .env file exists in the same directory as the server code 3. Check file permissions: ls -la .env (should show -rw-------)

✅ Security Benefits: - ✅ Secure file permissions (600 - owner only) - ✅ Git-ignored by default (won't be committed) - ✅ Local to project directory (easy to manage) - ✅ Standard .env pattern (familiar to developers) - ✅ No credentials in config files (improved security)

Remote MCP Server (Advanced)

User Authorization Flow

Server Deployment: Deploy the remote server to your hosting environment
User Authorization: Users visit https://your-server.com/oauth/authorize
Credential Entry: Users securely enter their Kaltura credentials via web form
Token Generation: Server generates a JWT token with encrypted credentials
Client Configuration: Users add the server URL and token to their MCP client

Step-by-Step Remote Setup

1. Generate Secure JWT Secret

# Generate a strong secret key
python -c "import secrets; print(secrets.token_urlsafe(32))"

2. Configure Environment

# Set in your .env file or environment
JWT_SECRET_KEY=your-generated-secret-key-here
OAUTH_REDIRECT_URI=https://your-domain.com/oauth/callback
SERVER_HOST=0.0.0.0
SERVER_PORT=8000

3. Deploy Server

Option A: Direct Python

kaltura-mcp-remote

Option B: Docker

docker-compose up -d

Option C: Production with Gunicorn (Optional)

# Install gunicorn separately if needed for production
pip install gunicorn
gunicorn -w 4 -k uvicorn.workers.UvicornWorker kaltura_mcp.remote_server:app

4. User Onboarding

Send users to: https://your-server.com/oauth/authorize?response_type=code&client_id=kaltura-mcp&redirect_uri=https://your-server.com/oauth/callback&state=user123

5. Client Configuration

For Claude Desktop (Remote Mode):

The easiest way to use the remote server with Claude Desktop is via the proxy client:

{
  "mcpServers": {
    "kaltura-remote": {
      "command": "kaltura-mcp-proxy",
      "env": {
        "KALTURA_REMOTE_SERVER_URL": "https://your-server.com/mcp/messages",
        "KALTURA_REMOTE_ACCESS_TOKEN": "your-jwt-token-from-authorization-flow"
      }
    }
  }
}

The proxy client (kaltura-mcp-proxy) acts as a local stdio MCP server that forwards requests to your remote server. This provides the best compatibility with Claude Desktop.

For Custom MCP Clients:

// HTTP transport with authentication
const transport = new HTTPTransport({
  baseUrl: "https://your-server.com/mcp/messages",
  headers: {
    "Authorization": "Bearer user-jwt-token-here"
  }
});

Security Considerations

Production Deployment

Use HTTPS: Always deploy with TLS/SSL certificates
Secure JWT Secret: Use a cryptographically strong secret key (32+ bytes)
Environment Security: Never commit secrets to version control
Network Security: Use firewalls and VPN access where appropriate
Regular Updates: Keep dependencies updated for security patches

JWT Token Security

Token Expiration: Tokens expire after 24 hours by default
Credential Encryption: Kaltura credentials are encrypted within JWT payload
Scope Limitation: Tokens are limited to read-only Kaltura operations
Revocation: Restart server to invalidate all existing tokens

Infrastructure

# Example nginx configuration for production
server {
    listen 443 ssl;
    server_name your-kaltura-mcp.com;

    ssl_certificate /path/to/cert.pem;
    ssl_certificate_key /path/to/key.pem;

    location / {
        proxy_pass http://localhost:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}
