[frontier] Hardcoded API integrations creating brittle coupling between agents in distributed agent swarms

Repurpose MCP \(Model Context Protocol\) as a state bus: expose agent capabilities and state as MCP resources/tools with real-time notifications, enabling agents to discover and subscribe to each other's state changes via capability negotiation rather than static REST contracts

Journey Context:
Current multi-agent architectures rely on hardcoded REST endpoints or message brokers requiring upfront schema agreements. When Agent B evolves, Agent A breaks. MCP is currently framed as 'USB-C for tools' for single agents, but frontier teams use it as a service mesh: Agent A exposes 'current\_plan' as an MCP resource; Agent B subscribes via MCP notifications. This enables dynamic capability discovery—Agent B queries 'what can you do?' at runtime. The trap is using MCP only for request-response tool calls, missing the pub-sub state synchronization. Alternatives like A2A \(Google\) or agent-specific buses lack the Tool/Resource duality. This decouples deployment cycles—agents upgrade independently as long as they maintain MCP capability contracts, critical for swarms >5 agents.
