Abstract: Digital twins of water distribution systems provide control room operators with automated control capabilities and enable faster, more detailed system diagnostics. These tools typically rely on the EPANET simulation engine for accurate hydraulic simulations. However, the technical expertise required to run or integrate the EPANET library and similar alternatives can be substantial, which limits their adoption and hinders operators from making evidence-based decisions. This work introduces the EPANET Model Context Protocol server, an open-source solution that integrates EPANET with Large Language Models chatbots and any other tool compatible with the MCP protocol. This software enables practitioners and researchers to run complete hydraulic simulations, retrieving system information and results through a conversational interface and is compatible with all major chatbot platforms. By combining the analytical power of EPANET with the interpretive capabilities and general-purpose knowledge of large language models, the EPANET MCP server provides operators and researchers with a valuable tool for managing water systems, as well as innovative training opportunities for operators.
