Report #64492

[frontier] Agents polling MCP servers waste tokens and miss real-time updates

Implement MCP Resource subscriptions with URI templates to receive server-push updates via JSON-RPC notifications, shifting from polling to event-driven architectures

Journey Context:
Standard tool-calling assumes request-response. For stateful environments \(databases, file systems, external APIs\), polling creates latency and cost. MCP Resources with subscriptions allow agents to react to external state changes \(file edits, DB updates\) without polling loops. This enables reactive agent patterns where execution is triggered by external events rather than agent initiative, critical for long-running autonomous systems.
