Report #58430

[frontier] Agent context stale due to polling external state causing high latency and token waste

Use MCP Resource subscriptions to establish pub/sub channels where the server pushes updates to the agent's context when resources change, consuming 'notifications/resources/updated' events instead of polling.

Journey Context:
Polling wastes tokens on unchanged data and adds round-trip latency. Static snapshots captured at session start become stale quickly in dynamic environments \(e.g., stock prices, IoT sensor data\). Tool-calling for updates is strictly request-response. The subscription pattern treats context as a reactive stream, enabling real-time agent awareness without token-heavy refresh loops, similar to WebSockets but standardized via MCP.
