[frontier] How to share ephemeral state and memory between agents without building custom message queues or shared databases?

Expose memory and state as MCP Resources \(not just Tools\) with URI schemes like 'memory://session/123'; agents read/write state via standard MCP resource requests, using subscriptions for reactive updates.

Journey Context:
MCP is typically used for tools \(functions\), but using Resources for state exposes read-only or read-write data with URI addressing, enabling a decentralized state bus. This replaces Redis/pub-sub for agent state by using the MCP protocol layer. Tradeoff: MCP servers become stateful \(or proxy to databases\), adding complexity, but standardizes state access patterns across heterogeneous agents.
