[frontier] Agents need real-time shared state but polling MCP servers causes latency and race conditions in multi-agent systems

Use MCP Resource Subscriptions \(JSON-RPC notifications\) to push state changes to subscribing agents, treating MCP as a state bus rather than a synchronous RPC bridge

Journey Context:
Teams initially use MCP like REST APIs—call tool, get result. But multi-agent systems need pub-sub to maintain shared world models without N^2 polling loops. The MCP 2024-11-05 spec added lifecycle methods including notifications and subscriptions for resources. By implementing 'MCP State Channels' where agents publish state updates to resources like 'memory://shared-context' and others subscribe via JSON-RPC notifications, systems achieve eventual consistency without the 'thundering herd' problem of status-quo polling. This is critical for real-time collaborative agents where latency <100ms matters.
