Report #54775

[frontier] Agents lose context between sessions because MCP is used only for ephemeral tool calling, not for persistent state management

Treat MCP Resources \(not just Tools\) as the canonical state layer—expose application state as readable resources \(e.g., \`user://preferences\`, \`project://config\`\) with binary content support that agents read before acting, and use Tools only for mutations, creating a state machine where Resources represent state and Tools represent transitions

Journey Context:
Current MCP implementations use UTF-8 text for everything, forcing expensive serialization of binary data \(images/audio\) or state. The spec actually supports binary blobs in Resources. By treating Resources as the 'read model' and Tools as the 'write model', you get caching, subscriptions, and clean separation. The complexity is handling binary base64 encoding \(33% overhead\) and cache invalidation when Tools mutate state.
