Report #72331

[frontier] Agents waste tokens polling APIs for external state changes or operate on stale context between turns

Use MCP Resource Subscriptions \(server-sent notifications\) to push state changes to agents. Implement MCP servers that support resource/update subscriptions rather than requiring client polling or static snapshots.

Journey Context:
Static context snapshots become stale immediately; polling is inefficient and high-latency. The fix is treating MCP resources as reactive event streams using the protocol's native subscription capability \(notifications on resource changes\), not HTTP polling or manual refresh patterns.
