"page_views_Ask with this source
A prompt for your agent that names this source and how to call it through the crw MCP.
Catalogue search
Use performance.cookcountyil.gov (performance-cookcountyil-gov) from fastCRW Pergamon, capability "Catalogue search" (catalog-search). You want to find a dataset on this portal by keyword and do not know its four-by-four id. Example options: q=taxi, offset=0, order=page_views_total DESC. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "performance-cookcountyil-gov" and capability "catalog-search". 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>
Dataset metadata
Use performance.cookcountyil.gov (performance-cookcountyil-gov) from fastCRW Pergamon, capability "Dataset metadata" (dataset). You already hold a dataset id and need its columns, licence or description before querying rows. Example options: id=53u2-p679. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "performance-cookcountyil-gov" 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>
Dataset inventory
Use performance.cookcountyil.gov (performance-cookcountyil-gov) from fastCRW Pergamon, capability "Dataset inventory" (datasets). You need to enumerate what this portal publishes, or page through its newest datasets. Example options: offset=0, order=createdAt, category=Transportation. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "performance-cookcountyil-gov" 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>
Row count
Use performance.cookcountyil.gov (performance-cookcountyil-gov) from fastCRW Pergamon, capability "Row count" (row-count). You need to know how large a dataset is before downloading it, or want a cheap liveness check. Example options: id=53u2-p679. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "performance-cookcountyil-gov" and capability "row-count". 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
No licence is declared in the dataset metadata this portal exposes through its catalogue API. No reuse grant is made here: commercial use and redistribution are recorded as false and no rights are claimed over the upstream data.
