Ask with this source
A prompt for your agent that names this source and how to call it through the crw MCP.
DCAT-US catalogue
Use opendataportal-lasvegas.opendata.arcgis.com (opendataportal-lasvegas-opendata-arcgis) from fastCRW Pergamon, capability "DCAT-US catalogue" (dcat-catalog). You want a standards-shaped harvest of the entire portal rather than keyword search hits. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "opendataportal-lasvegas-opendata-arcgis" and capability "dcat-catalog". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
Item detail
Use opendataportal-lasvegas.opendata.arcgis.com (opendataportal-lasvegas-opendata-arcgis) from fastCRW Pergamon, capability "Item detail" (item). You have an ArcGIS item id from a search and need its metadata and service URL. Example options: id=f6b923ee5eb9450baf6adebaf0f307ed. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "opendataportal-lasvegas-opendata-arcgis" and capability "item". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
Item search
Use opendataportal-lasvegas.opendata.arcgis.com (opendataportal-lasvegas-opendata-arcgis) from fastCRW Pergamon, capability "Item search" (items). You want to find data layers or maps on this ArcGIS portal by keyword or by map extent. Example options: q=crime, bbox=-77.1,38.8,-76.9,39.0, filter=type:("Feature Service"). Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "opendataportal-lasvegas-opendata-arcgis" and capability "items". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
