[frontier] How to share context between multiple AI agents without overflowing the orchestrator prompt

Implement MCP \(Model Context Protocol\) as a stateful shared blackboard server rather than just stateless tool execution. Use MCP Resources for read-heavy shared context and MCP Tools for state mutations, allowing agents to read/write to a shared scratchpad asynchronously.

Journey Context:
Teams initially treat MCP as REST-like stateless tool calling. This fails in multi-agent setups because context must be passed via the orchestrator prompt, hitting token limits and increasing latency. By using MCP as a stateful shared memory \(blackboard pattern\), agents query only the context they need when they need it, drastically reducing orchestrator context bloat and enabling loosely coupled agent topologies.
