Report #64296

[frontier] Multi-agent systems fail to maintain shared mutable state across tool boundaries, leading to race conditions and stale context

Use MCP Resources \(not just Tools\) to expose mutable state with subscription patterns. Treat MCP server as a state bus: agents subscribe to resource URIs \(e.g., \`state://session/order-123\`\), receive Server-Sent Events on mutation, and write back via tool calls validated by server-side conflict resolution \(ETag/version vectors\).

Journey Context:
Treating MCP as mere RPC tool registry misses the 'Context' in Model Context Protocol. Resources provide first-class entities with lifecycle. This replaces ad-hoc Redis/pub-sub between agents with protocol-native state sync. Tradeoff: tight coupling to MCP spec vs. interoperability.
