## Common Patterns

### Authentication

Each component uses its own authentication method:

* **MCP Hub**: API key or token-based authentication
* **MCP Chatbot**: Inherits authentication from MCP Enterprise

### Response Format

All APIs follow a standard response format:

```json theme={null}
{
  "success": true,
  "data": {
    // Response data
  },
  "error": null
}
```

### Error Handling

Standard error format:

```json theme={null}
{
  "success": false,
  "data": null,
  "error": {
    "code": "ERROR_CODE",
    "message": "Human readable error message"
  }
}
```
