Report #49530

[frontier] MCP servers limited to text preventing computer vision and audio workflows

Extend MCP servers to handle image/png and audio/wav content types via base64 data URIs in content arrays with appropriate MIME types

Journey Context:
Text-only MCP limits tool use to APIs. Supporting image \(base64 PNG\) and audio enables computer vision tools and speech pipelines within the same protocol. Clients must render/process media. Tradeoff: increased payload sizes and latency, requires base64 encoding overhead. Alternative was separate HTTP endpoints for media, breaking the unified protocol and auth model.
