Ask with this source
A prompt for your agent that names this source and how to call it through the crw MCP.
Active tropical cyclones
Use NOAA National Hurricane Center (nhc) from fastCRW Pergamon, capability "Active tropical cyclones" (active-storms). You want to know what storms are running right now, anywhere NHC or CPHC forecast, before you look up anything storm-specific. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "nhc" and capability "active-storms". 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>
Current advisory wind field
Use NOAA National Hurricane Center (nhc) from fastCRW Pergamon, capability "Current advisory wind field" (advisory-wind-field). You want how far out damaging winds reach from the storm centre at this moment. Example options: resultRecordCount=50, resultOffset=0, returnGeometry=false. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "nhc" and capability "advisory-wind-field". 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>
Watch and warning breakpoints
Use NOAA National Hurricane Center (nhc) from fastCRW Pergamon, capability "Watch and warning breakpoints" (breakpoints). You need the official place names NHC draws watch and warning boundaries between, for example to parse an advisory. Example options: resultRecordCount=50, resultOffset=0, returnGeometry=false. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "nhc" and capability "breakpoints". 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>
Forecast cone of uncertainty
Use NOAA National Hurricane Center (nhc) from fastCRW Pergamon, capability "Forecast cone of uncertainty" (forecast-cone). You need the official uncertainty footprint of a forecast track, for example to test whether a location falls inside the cone. Example options: resultRecordCount=50, resultOffset=0, returnGeometry=false. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "nhc" and capability "forecast-cone". 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>
