Report #77434

[frontier] Agent loses all progress when context resets or when switching between different LLM providers

Use MCP resources with write capabilities \(binary blob resources or JSON files\) to persist agent memory, reasoning traces, and few-shot examples to external storage via MCP servers

Journey Context:
Agents traditionally store memory in the context window or external vector DBs requiring separate clients. The MCP 2025-03-26 spec defines resources that can be read AND written \(via server capabilities\). Advanced agents now treat the filesystem, key-value stores, or cloud storage as MCP resources they read/write to maintain state across sessions. This creates 'memory MCPs' that are provider-agnostic. Unlike function calling which is ephemeral, resource writes persist. Alternative: tool-calling for persistence creates impedance mismatch; resources are the correct abstraction for state.
