[frontier] Agent wastes tokens polling MCP servers for resource updates instead of receiving real-time notifications

Subscribe to MCP resource changes using the notifications/resources/updated protocol, eliminating polling loops and enabling event-driven reactive agent architectures

Journey Context:
Agents traditionally poll APIs in loops to detect changes, wasting tokens and adding latency. The fix leverages MCP's native pub/sub model: the client subscribes to specific resource URIs \(resources/subscribe\), and the server pushes notifications via notifications/resources/updated when content changes. This transforms agents from polling loops into event-driven systems that react immediately to external state changes \(file updates, database changes\) without consuming context window on redundant status checks.
