Report #88720
[frontier] How do agents share persistent state without a database in MCP architectures?
Use MCP Resources \(not just Tools\) to expose mutable state as URI-addressable content that agents can read/write via the protocol, treating the MCP server as a stateful memory bus.
Journey Context:
Teams initially use MCP only for tool calling \(functions\), hitting limits when agents need shared context across sessions. Databases add latency and schema coupling. The insight: MCP Resources were designed for contextual data exposure—using them for state turns the MCP server into a lightweight, protocol-native memory layer with built-in URI addressing and subscription capabilities.
