[frontier] How to keep agent context synchronized with external data sources without constant polling overhead?

Use MCP resource subscriptions to establish server-push updates, where the server notifies the agent of resource changes via notifications rather than the agent polling for updates.

Journey Context:
Polling wastes tokens and adds latency; most implementations fetch static snapshots at workflow start. Subscriptions enable reactive agents that respond to live data changes \(prices, build status, file edits\) immediately. Tradeoff: requires persistent connections, handling reconnection logic, and managing subscription lifecycle. Critical for real-time agent applications where stale context causes incorrect decisions.
