[frontier] How to maintain real-time state between an AI agent and external APIs without polling?

Use MCP Resources \(not just Tools\) to establish stateful subscriptions: expose external state as addressable resources with change notifications, allowing the server to push updates to the agent via the MCP notification channel.

Journey Context:
Standard MCP usage treats it as an RPC layer for tools \(request-response\). However, the MCP specification defines Resources and Notifications for exactly this use case. Instead of the agent polling a 'get\_status' tool, the server exposes a resource URI \(e.g., 'status://job-123'\) and sends notifications when it changes. This transforms MCP from a tool-calling protocol into a state synchronization protocol, critical for long-running agent workflows where state changes external to the agent.

environment: Long-running data processing jobs, IoT device monitoring, or multi-step workflows where external system state changes asynchronously and the agent must react without polling overhead. · tags: mcp state-synchronization resources notifications protocol · source: swarm · provenance: https://spec.modelcontextprotocol.io/specification/2024-11-05/server/resources/
