    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('Verify my Mailsoftly API key and show account details')
        async for message in client.receive_response():
            if hasattr(message, 'content'):

                    if hasattr(block, 'text'):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText, stepCountIs } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: mcp.url,
    headers: { 'x-api-key': 'your-composio-api-key' }
  }
});

const tools = await client.tools();

const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{ role: 'user', content: 'Verify my Mailsoftly API key and show account details' }],
  stopWhen: stepCountIs(5)
});
