Report #73520

[frontier] Cannot process images or audio through MCP because protocol only supported text

Use MCP 2025-03-26 binary content support to transmit base64-encoded images and audio as resource contents, enabling multi-modal agents through the same protocol as text tools.

Journey Context:
Earlier MCP versions were text-centric. Binary support standardizes how agents access visual/audio resources. Alternative: separate API calls \(breaks abstraction\). Tradeoff: base64 encoding overhead but unifies resource access patterns across modalities.
