Remarks

BlobResourceContents is used when binary data needs to be exchanged through the Model Context Protocol. The binary data is represented as base64-encoded UTF-8 bytes in the Blob property.

This class inherits from ResourceContents, which also has a sibling implementation TextResourceContents for text-based resources. When working with resources, the appropriate type is chosen based on the nature of the content.

See the schema for more details.
