Memgraph MCP Experimental Server: Elicitation and Sampling Explained

Memgraph's experimental server introduces the concepts of Elicitation and Sampling within the Model Context Protocol (MCP) to enhance user interaction and optimize database queries. Elicitation allows servers to request additional structured information from users via clients, creating an interactive workflow where users can dynamically provide input. Sampling involves the server delegating language model calls to the client, enabling the analysis and optimization of Cypher queries by recommending appropriate indexes. This approach facilitates a user-controlled optimization process, where users can choose whether to create suggested indexes, thereby ensuring transparency and control. The experimental server's workflow, demonstrated through examples, showcases its ability to analyze queries, identify missing indexes, and prompt users for index creation, ultimately aiming to improve system adaptability and lay the groundwork for autonomous GraphRAG workflows.
