Aquaview MCP

Search the AQUAVIEW catalog — a comprehensive collection of 268K+ global oceanographic, atmospheric, and marine datasets from 15 sources (NOAA, NDBC, IOOS, WOD, CoastWatch, etc.), intended for scientific research, data analysis, and environmental monitoring. This searches METADATA — which datasets exist. To pull the actual observations (temperature profiles, buoy readings, float positions), u

Fetch a single AQUAVIEW dataset item with full details, properties, and download links (assets). STAC items embed assets inline — each asset includes an href (download URL) and media type, so there is no need for a separate "files" call. Args: collection: The collection ID the item belongs to (e.g., "NOAA", "NDBC", "WOD"). Available from search results or list_collections. item_id: The

List all available AQUAVIEW data collections (sources). Returns a summary of each collection with ID, title, description, spatial/temporal extent, and keywords. Use collection IDs to filter searches. These are CATALOG collections. Several are also queryable row by row — see list_data_sources for the sources get_data can pull observations from. A collection's bbox and temporal range are OUTER

Run aggregation queries on the AQUAVIEW catalog — get counts, spatial distributions, temporal distributions, and per-collection breakdowns without fetching individual items. Args: aggregations: Comma-separated aggregation types (required). Valid types: total_count, datetime_max, datetime_min, datetime_frequency, collection_frequency, geometry_geohash_grid_frequency, geometry_geotile_grid_fr

List the AQUAVIEW data sources you can pull actual rows from, or describe one in detail. Call this BEFORE get_data on a source you have not used. Variable names are canonical per source and cannot be guessed — this is where they come from. With an API key, sources your account is entitled to appear here too. Args: source_id: Omit to list every visible source. Give one (e.g. "gadr") to get

Pull actual observation rows from an AQUAVIEW data source — not catalog metadata. Use this whenever the question needs the measurements themselves (temperature profiles, float positions, buoy readings), rather than which datasets exist. Call list_data_sources first for a source's canonical variable names, its `qc_modes`, and its `engine` (gridded "xarray" sources have no rows to pull). READ 'r
