Report #57160

[frontier] Agents operate on stale context because they poll MCP servers or rely on static file reads at startup

Implement MCP resources with subscription capabilities \(notifications/updates\) to push live context changes \(file edits, DB updates, log streams\) to agents in real-time via JSON-RPC notifications

Journey Context:
Static resources are like reading a book once. 2025 agents need live data streams—watching logs tail -f, seeing code edits as they happen. MCP 2025-03-26 spec supports resource subscriptions where servers push JSON-RPC notifications when resources change. This turns agents from batch processors into reactive systems, cutting latency from minutes to milliseconds for critical updates and enabling event-driven agent architectures.
