[frontier] MCP servers treated as stateless tool providers causing context loss between agent sessions
Leverage MCP Resources and subscriptions to maintain durable state across sessions, using MCP servers as state brokers that persist shared context \(memory, user preferences, session history\) via resource URIs rather than passing state through tool arguments.
Journey Context:
Developers initially implement MCP as pure function calls \(tools\), losing state between invocations. The insight is that MCP Resources are designed for exactly this: a server can expose 'user://preferences' as a resource that persists between tool calls. This decouples state management from the agent's context window, allowing multi-agent shared memory without context pollution. Common pitfall: trying to pass state via tool parameters instead of resource subscriptions.
