Workflow: search_sources → get_source → advertised router_tools. Inspect tools/list for exact schemas. Confirm site coordinates; location_hints are approximate.
Discovery: search_sources, get_source, list_categories, top_sources, get_consultant.
Live: flood_find_stations, flood_get_readings, rainfall_stations, rainfall_latest, ea_hydro_series, nrfa_station_info, nrfa_get_timeseries, wq_*, sepa_*, bgs_*, planning_entities, flood_zone_at_point, tide_*.
For FRA evidence, combine site-specific flood polygons, river/rainfall records, long-term flow, geology and planning; observations are not forecasts or design levels. For York river levels, find nearby stations then request readings. For Salford geology, inspect BGS collections then bounded features.
Preserve source URL, retrieval/observation times, station IDs, licence attribution, units and datum. Missing/truncated data are unknown. dem_clip requires TerraMCP and OpenTopography keys; upstream commercial rights still apply.
