Report #69804

[frontier] Agent polling APIs constantly for live data updates causing high latency and token costs

Implement MCP Resource subscriptions with URI templates; use server-push notifications instead of request/response polling for live data sources

Journey Context:
Developers initially use MCP only for Tools \(calculators, search\), treating it as a RPC mechanism. When they need live data \(file changes, DB updates, stock prices\), they resort to polling loops in the agent. The frontier pattern is using MCP Resources with the 'subscribe' capability. The server maintains subscriptions and pushes notifications when resources change, eliminating polling latency and reducing token waste by avoiding redundant context re-sending. This requires restructuring your server to support resource templates and notification hooks, shifting from a pull to a push architecture.
