LangGraph bot uses MCP Resource for persistent episodic memory

A developer encountered an issue with a support bot built using LangGraph, where the bot repeatedly forgot conversation context. The problem stemmed from using a simple in-memory store for episodic memory, which was lost upon bot restarts. To resolve this, the developer implemented a solution using the Resource primitive from the Model Context Protocol (MCP) to persist and retrieve the bot's episodic memory across interactions. AI
