[frontier] How to manage real-time state synchronization between AI agents and external data sources without constant polling

Use MCP Resource Subscriptions with URI-based resources and subscription primitives instead of treating MCP only as a tool-calling framework. Implement resource update notifications to push state changes to agents.

Journey Context:
Teams initially used MCP only for tools \(functions\), polling for state changes. This causes high latency and token waste. The March 2025 MCP spec formalized Resource Subscriptions \(uri-based, subscribable resources\) which treat state as first-class, enabling push-based agent updates. Alternative: GraphQL subscriptions or polling loops, but these lack the agent-native URI addressing and permission scoping of MCP. This matters because it decouples agent reasoning from state-fetching logic, allowing real-time multi-agent collaboration on shared resources.
