Click New > New Service
Fill in the service details:
- Service: Custom
- Display Name: (e.g., "MCP Server")
Save the provided Client ID and Client Secret

2. Configure Environment Variables

Create a .env file in the root directory:

# Your Marketo instance URL (required)
# Example: https://123-ABC-456.mktorest.com/rest
MARKETO_BASE_URL=your-marketo-instance-url

# Your API credentials (required)
MARKETO_CLIENT_ID=your-client-id
MARKETO_CLIENT_SECRET=your-client-secret

3. Installation and Setup

# Install dependencies
npm install

# Build the project
npm run build

# The build process will output configuration settings in your console
# Copy these settings into your Claude Desktop developer configuration

4. Claude Desktop Configuration

Open Claude Desktop
Go to Developer Settings
Paste the configuration settings that were output during the build process
Save the configuration
Restart Claude Desktop

Error Handling

Common error scenarios and solutions:

Authentication Errors
- Verify your Client ID and Client Secret are correct
- Check that your API access is enabled in Marketo
- Ensure your instance URL is correct
Permission Errors
- Verify your API user has sufficient permissions
- Check folder access permissions for form operations
Rate Limiting
- The server automatically handles token refresh
- Consider implementing retry logic for rate-limited requests

Best Practices

Environment Management
- Never commit .env files to version control
- Use different credentials for development and production
- Regularly rotate your API credentials
Security
- Store credentials securely
- Use environment variables for sensitive data
- Monitor API access logs
Performance
- Cache form data when appropriate
- Use pagination for large form lists
- Handle rate limits appropriately
