Eleven MCP servers exposing a reproducible EPA SWMM stormwater-modelling workflow: model building, simulation runs with manifests and continuity checks, calibration, GIS/QGIS integration, design storms and climate scenarios, uncertainty analysis, plotting, and modelling memory. Config generators included for Codex, Claude Code, OpenClaw, and Hermes.
Latest instantaneous (real-time) readings for one or more USGS gauge sites. Returns the most recent value per site × parameter — e.g. current streamflow and gage height for a river. Common parameter codes: 00060 = discharge/streamflow (ft³/s), 00065 = gage height (ft), 00010 = water temperature (°C…
daily_values
Daily-values time series for a single USGS site + parameter over a date range. Returns one statistic per day (default mean). Useful for trends, hydrographs, and historical comparison. Common statCd: 00003 = mean, 00001 = max, 00002 = min. Common parameter codes: 00060 = discharge (ft³/s), 00065 = g…
find_sites
Discover active USGS gauge sites in a US state that are currently reporting a given parameter (real-time). Returns sites with their latest reading; useful for finding which gauges are live in a region. Can match many sites, so results are capped. Keyless.
