```

## Parameters

**messageIds** (`string[]`): Array of message IDs to delete

## Returns

## Extended usage example

```typescript
import { mastra } from './mastra'
import { MastraDBMessage } from '@mastra/core'

const agent = mastra.getAgent('agent')
const memory = await agent.getMemory()

const { messages } = await memory!.recall({ threadId: 'thread-123' })

const messageIds = messages.map((message: MastraDBMessage) => message.id)
await memory?.deleteMessages([...messageIds])
```
