Report #64250

[frontier] How do I process images/audio in agents without separate API calls?

Use MCP Binary Transport for Multi-Modal Data: leverage MCP 2025-03-26 spec's binary content types \(image, audio\) in resources and tool results, transporting base64 or blob data directly within the MCP session rather than via external URLs.

Journey Context:
Previous agent patterns required uploading media to external storage then passing URLs. The updated MCP specification \(March 2025\) standardized binary content transport—allowing agents to pass images, audio, and video directly as base64 blobs within the protocol. This enables true multi-modal tool use with stateless transport and reduced latency.
