Report #40582

[frontier] Agent fails to react to real-time changes in external environments because it relies on polling MCP resources

Utilize MCP Resource Subscriptions and event-driven triggers. Instead of the agent periodically asking if a resource has changed, register a subscription with the MCP server and use an interrupt-handler pattern to wake the agent only when state changes.

Journey Context:
Polling is the default mental model for HTTP-based agents, but it burns tokens and introduces latency. If an agent is waiting for a CI/CD pipeline to finish, polling every minute is expensive and slow. The MCP spec supports subscriptions for resources. Wiring these to agent interrupts allows agents to sleep \(costing zero tokens\) until an event actually occurs.
