EPANET MCP servers and AI agent skills

How AI connects to EPANET

An MCP server or skill can only do what EPANET lets programs do. EPANET exposes 3 automation interfaces:

• EPANET Programmer's Toolkit (C API) (Other): The Programmer's Toolkit is a C library that lets other programs call EPANET's hydraulic and water quality engine, and the open-source OWA-EPANET 2.3 version adds functions to set and retrieve every parameter in a network. EPA still ships the 2.2 toolkit files. The command-line runner, runepanet.exe, takes an .inp file and writes an .rpt report, which is the whole interface the Renzodasu server uses. Documentation
• EPyT and WNTR (Python) (Python): EPyT, from the KIOS centre, wraps the toolkit for Python and is what both the KWR and Eurecat servers use. EPA's WNTR is an EPANET-compatible Python package for resilience analysis of distribution networks. According to the Renzodasu README, EPyT ships EPANET 2.3.05, so results can differ slightly from the 2.2 GUI that a specification or reviewer may expect. Documentation
• Network .inp files (Input files): Networks are text .inp files with sections for junctions, reservoirs, tanks, pipes, pumps, valves, patterns, curves, controls and options. Units follow the flow unit chosen in options, so a diameter of 12 means inches under GPM and millimetres under LPS, a common silent error when an agent writes a network. Documentation

What US EPA offers

EPA hasn't published an MCP server, skill or AI assistant for EPANET. Its EPANET page lists the 2.2 installer, toolkit, source code and online manual, calls EPANET public domain software and points to the GitHub open-source project for continued development. The listed servers come from KWR, Eurecat and an individual developer.

What you can do with EPANET and AI

• Find the junctions with the lowest pressure at a given hour, or every pipe above a velocity limit.
• Change a demand, pipe diameter, pump speed or valve setting, rerun and compare pressures with the base network.
• Simulate a pipe burst, a contamination injection or a pump outage on a cloned network and report which customers lose service.
• Build a small network from a description, solve it in EPANET 2.2 and check it for disconnected nodes, negative pressures and mass balance errors.
• Plot the network and pressure or velocity maps as images in the chat.

Installing

The listings here document setup for Claude Code, Claude Desktop, Codex and VS Code. Install steps, copied from each project's own documentation, are on each listing's page. Most EPANET integrations run on your own computer next to EPANET, so you need EPANET installed and licensed on the same machine unless the listing says otherwise.
