[frontier] How do I keep my AI agent updated with live server state without constant polling?

Use MCP Resource Subscriptions: define resources with update callbacks in your MCP server, subscribe to them from the client, and receive push updates when state changes instead of polling.

Journey Context:
Polling tool calls wastes tokens and latency. Most devs use MCP only for tools, missing that Resources support subscription models for live data \(like file watches or DB changes\). Tradeoff: requires maintaining persistent connections but eliminates polling loops. Alternatives: SSE streams or WebSockets, but MCP subscriptions standardize the protocol.
