Amazon Bedrock Adapter

The Bedrock adapter is the default engine for memoryblock. It uses the official @aws-sdk/client-bedrock-runtime and supports Claude 3 and 3.5 models.

Configuration

Update your block’s config.json (_playground/memoryblock-ws/blocks/<block-name>/config.json):

{
  "adapter": {
    "provider": "bedrock",
    "model": "anthropic.claude-3-5-sonnet-20241022-v2:0",
    "region": "us-east-1",
    "maxTokens": 4096,
    "cacheControl": true
  }
}

Authentication

Add your AWS credentials to your workspace auth.json:

{
  "aws": {
    "accessKeyId": "AKIA...",
    "secretAccessKey": "...",
    "region": "us-east-1"
  }
}

Or run mblk init to set them up interactively.
