Report #26974

[frontier] Agent polling external API causes high latency and stale data in multi-turn workflows

Implement MCP Resource subscriptions with notifications; configure server to push updates via \`notifications/resources/updated\` instead of client polling

Journey Context:
Traditional tool-calling assumes request-response; for live data \(stock prices, CI status\), polling wastes tokens and adds latency. MCP subscriptions allow servers to push updates when resources change. Tradeoff: requires persistent connection \(SSE/stdio\) and handling out-of-order notifications. Alternative: long-polling HTTP is simpler but less efficient for high-frequency updates.
