[frontier] MCP tool-only implementations hitting token limits and state synchronization failures

Use MCP Resources \(not just Tools\) to expose dynamic state, files, and agent memory via URI-addressable endpoints, enabling real-time synchronization without bloating the context window.

Journey Context:
Teams initially use MCP only for Tools \(functions\), causing them to dump large state into tool results, hitting token limits and losing state between turns. Resources are designed for entity-centric data exposure with subscription patterns, but most implementations ignore them in favor of stateless tool calls. The tradeoff is architectural complexity \(managing resource URIs and subscriptions\) vs. unbounded context growth and state inconsistency. This is correct because it treats state as addressable references rather than inline text, following REST principles that scale and allow agents to fetch only the slices of state they need.
