[frontier] How to share state between multiple AI agents without context window overflow

Use MCP resource servers as a shared memory layer. Expose structured state \(task progress, shared facts, working memory\) via MCP resources that any agent can read on-demand. This decouples shared state from individual agent context windows.

Journey Context:
The naive approach is to pass full conversation history between agents or through an orchestrator, which exhausts context windows and creates tight coupling. MCP defines three primitives: tools \(actions\), resources \(data\), and prompts \(templates\). Most implementations only use tools, missing that resources provide a standardized way to expose readable state that agents query on-demand rather than carrying in context. The key insight: resources are pull-based \(agent reads when needed\) vs push-based \(stuffing context\), giving agents agency over what context they consume. Tradeoff: requires designing a resource schema and server, but eliminates the context explosion problem in multi-agent systems.
