Report #55542

[frontier] Agents losing persistent state across tool calls and session restarts

Use Model Context Protocol \(MCP\) servers as persistent state stores via the resource and sampling patterns rather than stateless tool wrappers

Journey Context:
Standard tool calling loses context between invocations. MCP's resource paradigm allows agents to maintain persistent state across sessions. Emerging production pattern treats MCP servers as 'memory servers' with CRUD resources that survive agent restarts.
