Ask with this source
A prompt for your agent that names this source and how to call it through the crw MCP.
Dataset detail
Use data.public.lu (datapubliclu) from fastCRW Pergamon, capability "Dataset detail" (dataset). You already have a data.public.lu dataset id or slug and need its metadata and downloadable files. Example options: id=etat-de-la-population-population-structure. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "datapubliclu" and capability "dataset". 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>
Search datasets
Use data.public.lu (datapubliclu) from fastCRW Pergamon, capability "Search datasets" (datasets). You want to find Luxembourg public datasets by keyword, publisher, tag, licence or file format. Example options: q=mobilité, page=1, sort=-last_update. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "datapubliclu" and capability "datasets". 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>
Discussion threads
Use data.public.lu (datapubliclu) from fastCRW Pergamon, capability "Discussion threads" (discussions). You want the questions, corrections and publisher replies attached to a dataset, organisation or user. Example options: for=6662a77d3966fe4cf3f76d01, org=statec-institut-national-de-la-statistique-et-des-etudes-economiques-du-grand-duche-de-luxembourg, closed=false. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "datapubliclu" and capability "discussions". 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>
Licence list
Use data.public.lu (datapubliclu) from fastCRW Pergamon, capability "Licence list" (licenses). You need the valid licence ids to filter dataset search, or want to check the reuse terms of Luxembourg open data. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "datapubliclu" and capability "licenses". 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>
