io.github.cyanheads/usgs-water-mcp-server · Verify this server

Find USGS water monitoring sites by bounding box, state, county, or HUC watershed code, filtered by site type and parameter availability. Returns site numbers, names, coordinates, types, altitude, and (in expanded mode) drainage area. Call this first — water_get_readings, water_get_series, and water_get_conditions all require a site number. Capped at 500 sites inline; when truncated=true, upstreamTotal holds the full count and, if DataCanvas is enabled, the complete match set stages to a canvas (canvas_id/table_name) for retrieval via water_dataframe_query — otherwise narrow the filters to get all matches.
