Report #74525

[frontier] Agent polling external APIs creates latency and stale state in multi-step workflows

Subscribe to MCP Resources with callbacks instead of polling; agents react to state changes via server-sent events

Journey Context:
Teams start with polling tools in MCP \(e.g., 'check\_status'\), hit rate limits and stale reads during long tasks. The shift is to implement MCP Resource subscriptions \(2024-11-05 spec\) where the server pushes deltas. Tradeoff: requires persistent connections vs stateless requests, but eliminates race conditions in multi-agent handoffs.
