Report #48898

[frontier] Multi-agent systems struggle to share state without tight coupling or polling APIs.

Use MCP \(Model Context Protocol\) Resources not just for static file access, but as a pub/sub shared memory bus. Implement a 'state server' exposing resources at URIs like 'state://session-123/memory'. Agents read/write to these resources using MCP tools. The server handles persistence, locking, and change notifications via the MCP protocol's resource update notifications.

Journey Context:
Message queues \(Redis/RabbitMQ\) require agents to know queue semantics. Direct API calls couple agents to specific implementations. MCP Resources were designed for 'context' but the spec allows dynamic resources that can represent computed state. Leading implementations \(Cursor, Claude Desktop\) are beginning to use MCP for live state synchronization. This pattern decouples agents via a standard protocol: agents don't know about each other, only about the MCP resource URI. It's the difference between 'calling a service' and 'mounting a filesystem'.
