Documentation Overview
SWATGenX MCP Server
The agent-native front door to SWATGenX — automated, calibrated SWAT+ watershed modeling for the conterminous United States.
Add it to Claude or any MCP client and a continental watershed-modeling platform becomes a set of callable tools: search calibrated SWAT+ models, read calibration and held-out validation scores, query a national groundwater lithology inventory of ~28.8 million depth intervals, query a national PFAS monitoring inventory, and — with an API key — order and download watershed models.

About
SWATGenX builds physically based SWAT+ and coupled SWAT+/MODFLOW 6 models from NHDPlus HR hydrography, gSSURGO soils, NLCD land cover and PRISM climate, and calibrates them against USGS streamflow. The national groundwater inventory this server queries is described in a preprint under open review at Earth System Science Data (doi:10.5194/essd-2026-527).
The server implementation lives in the main SWATGenX repository; this repository holds the
registry manifest (server.json) and the publish workflow.
