Report #83914

[frontier] MCP servers only used for tool calling, missing state synchronization across distributed agents

Expose shared state as MCP Resources \(uri://memory/\{key\}\) with subscription-based updates, treating state as addressable resources rather than message payloads

Journey Context:
Teams initially pass full state in every MCP tool call, causing token bloat and race conditions. The frontier pattern uses MCP's Resource primitive \(distinct from Tools\) to expose mutable state with URI addressing. Agents subscribe to resource updates via server-sent events or polling, enabling reactive synchronization without tight coupling. This decouples 'who holds the state' from 'who acts on it', allowing stateful agents to be horizontally scaled. The critical shift is recognizing MCP as a resource-oriented architecture, not just RPC.
