}Run this in your terminal
claude mcp add epanet -- uvx epanet-mcp-serverOr copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{
"mcpServers": {
"epanet": {
"command": "uvx",
"args": [

Common questions
Is EPANET MCP Server safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 5 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.
What can I use instead?

EPANET MCP Server
A Model Context Protocol (MCP) server that exposes EPANET water-distribution network modelling capabilities through ePyT - the EPANET Python Toolkit.
Any MCP-compatible LLM can load water network models, run simulations, modify parameters, and generate complex what-if scenarios through natural language.
Features
| Category | Tools |
|---|---|
| Load & Inspect | load_network, unload_network, list_networks, list_bundled_networks, get_network_summary, get_nodes, get_links, get_patterns, get_controls, get_curves, get_options |
| Simulate | run_hydraulic_simulation, run_quality_simulation, run_full_simulation, get_pressure_at_time, get_flow_at_time |
| Modify | set_node_base_demand, set_pattern, add_pattern, set_pipe_diameter, set_pipe_roughness, set_pipe_status, set_pipe_length, set_pump_status, set_pump_speed, set_pump_head_curve, set_valve_setting, set_valve_status, set_tank_parameters, set_reservoir_head, set_simulation_duration, set_hydraulic_timestep, set_quality_timestep, set_quality_type, add_control, delete_control, save_network |
| Scenarios | create_demand_perturbation, create_leakage_event, create_contamination_event, create_pressure_change_scenario, create_pump_control_scenario, create_valve_control_scenario, create_multi_failure_scenario |
Requirements
pip install epyt mcpInstallation
git clone https://github.com/Applied-Artificial-Intelligence-Eurecat/epanet-mcp-server.gitcd epanet-mcp-server pip install -e .
Running the server
stdio (for Claude Desktop / Claude Code)
epanet-mcp-serveror
python -m epanet_mcp.server
SSE / HTTP
epanet-mcp-server --transport sse --port 8000Claude Desktop configuration
Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or the equivalent on your platform:
{"mcpServers": { "epanet": { "command": "epanet-mcp-server", "args": [] } } }
If not on PATH:
{"mcpServers": { "epanet": { "command": "python", "args": ["-m", "epanet_mcp.server"], "cwd": "/path/to/epanet-mcp-server/src" } } }
Claude Code (.mcp.json)
Place this in the root of your project or ~/.claude/:
{"mcpServers": { "epanet": { "command": "epanet-mcp-server", "args": [] } } }
Example interactions
Once the server is connected, you can ask things like:
"Load Net1.inp and show me a summary of the network."
"Run a full simulation and tell me which node has the lowest pressure at hour 12."
"Double the base demand at junction 11 and re-run the simulation. How does pressure change?"
"Simulate a burst on pipe 10 with a 20% leakage fraction."
"Inject 10 mg/L of chlorine at node 11 between hours 1 and 3 and show me the contamination spread."
"What happens to pressures if the reservoir head drops from 150 m to 120 m?"
"Schedule Pump 9 to start at 06:00 and stop at 22:00."
"Close pipes 10 and 11 and the pump simultaneously. Where are service disruptions?"
Architecture
src/epanet_mcp/├── server.py # FastMCP server – tool registration + entry point ├── session.py # Thread-safe registry of open ePyT sessions ├── utils.py # numpy → Python serialisation helpers └── tools/ ├── inspection.py # load / inspect network models ├── simulation.py # run hydraulic & quality simulations ├── modification.py# in-memory parameter changes └── scenarios.py # what-if scenario generators (clone + modify + run)
Session model: Each loaded network lives in a named session. Scenario tools automatically clone the source session into a new independent session so the baseline network is never mutated.
Running the tests
pip install pytestpytest tests/ -v
Bundled networks
ePyT ships with many standard benchmark networks including Net1, Net2, L-TOWN, Hanoi, Anytown, Balerma and others. Use list_bundled_networks to discover them all.
