Adding New Tools

1. Define the tool in src/tools/index.ts:

export const newTool: Tool = {
  name: 'bitrix24_new_action',
  description: 'Description of the new action',
  inputSchema: {
    type: 'object',
    properties: {
      // Define parameters
    },
    required: ['requiredParam']
  }
};

2. Add the execution handler:

case 'bitrix24_new_action':
  // Implementation
  return { success: true, result: 'Action completed' };

3. Add to allTools array and rebuild.

🔒 Security Considerations

• Webhook Security: Keep your webhook URL secret and rotate it regularly
• Environment Variables: Never commit .env files to version control
• Rate Limiting: The client includes built-in rate limiting (2 requests/second)
• Error Handling: Sensitive information is not exposed in error messages

🐛 Troubleshooting

Common Issues

"Webhook validation failed"

• Verify your webhook URL is correct
• Check that the webhook has appropriate permissions
• Ensure your Bitrix24 instance is accessible

"Cannot find module" errors

• Run npm install to install dependencies
• Ensure you've built the project with npm run build

Rate limiting errors

• The client automatically handles rate limiting
• If you see persistent rate limit errors, consider reducing request frequency

Debug Mode

Set NODE_ENV=development and LOG_LEVEL=debug in your .env file for detailed logging.
