[frontier] How to synchronize state between multiple agents using MCP beyond simple tool invocation

Implement MCP Resources as a bi-directional state bus using the Resource subscription pattern, treating resources as live state containers rather than static files, enabling pub-sub synchronization between agents.

Journey Context:
Teams initially use MCP only for tool calling \(request-response\), but hit walls when agents need shared working memory. The breakthrough is treating MCP Resources as first-class state containers with subscription/notification patterns. This shifts the architecture from stateless tool calls to stateful resource synchronization, requiring servers to support resource update notifications and clients to maintain local resource caches.
