[frontier] Agents poll for external data changes, wasting tokens on stale context and missing real-time events

Use MCP resource subscriptions to establish persistent connections where servers push updates to agents, treating resources as real-time streams rather than static snapshots

Journey Context:
Standard tool calling assumes request-response: agent asks, tool answers. For monitoring logs, dashboards, or user activity, polling wastes tokens and introduces latency. MCP Resources support 'subscriptions' \(spec 2024-11-05\) where clients subscribe to a resource URI, and servers push notifications when resources change \(via 'notifications/resources/updated'\). Production pattern: agents subscribe to log files, database changefeeds, or user activity streams via MCP resources, receiving Server-Sent Events \(SSE\) style updates. This eliminates polling loops and ensures agents act on fresh data. Implementation requires MCP servers that support the 'resources/subscribe' method and clients that handle asynchronous notifications. This pattern replaces webhook-based integrations for AI agents, providing a unified streaming interface. Critical for real-time agents \(trading, monitoring\) where stale data causes incorrect decisions.
