[frontier] How do I synchronize state between distributed AI agents without tight coupling?

Use Model Context Protocol \(MCP\) to expose stateful resources as URIs that agents can subscribe to via notifications, treating state changes as first-class events rather than function call returns.

Journey Context:
Teams initially used MCP only for tool calling, treating it like OpenAI functions. However, production failures emerged when agents needed to share long-lived context \(e.g., a shared whiteboard\). The breakthrough was using MCP's resource subscriptions \(notifications\) to push state updates to all subscribed agents, enabling true multi-agent statefulness without polling. Alternatives like Redis pub/sub work but couple agents to infrastructure; MCP keeps the abstraction at the protocol level.
