Report #77689

[frontier] How do I share mutable state between multiple AI agents without tight coupling or shared databases?

Use MCP \(Model Context Protocol\) servers as a shared state bus; expose memory segments as MCP resources with subscription support, allowing agents to read/write state via the protocol rather than direct database calls.

Journey Context:
Teams initially use MCP only for tools \(calculator, search\) but hit a wall when agents need shared context. Centralized databases create tight coupling and schema drift. Message queues add operational complexity. MCP resources support live subscriptions and bi-directional updates, effectively turning the MCP server into a reactive state bus. The tradeoff is slightly higher latency than raw Redis, but you gain protocol-level standardization and automatic schema validation via MCP type hints.
