  • Scan coverage counts

    Use GSA Site Scanning (gsa-site-scanning) from fastCRW Pergamon, capability "Scan coverage counts" (analysis). You want how many federal sites meet a condition, or how many agencies and domains it spans, and do not want to page thousands of records to count them. Example options: target_url_domain=nasa.gov, final_url_domain=nasa.gov, final_url_live=true. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "gsa-site-scanning" and capability "analysis". 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>

  • Scan record for one site

    Use GSA Site Scanning (gsa-site-scanning) from fastCRW Pergamon, capability "Scan record for one site" (website). You already have one specific .gov hostname and want its whole scan record without paging the list to find it. Example options: target_url=gsa.gov. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "gsa-site-scanning" and capability "website". 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>

  • Federal website scan results

    Use GSA Site Scanning (gsa-site-scanning) from fastCRW Pergamon, capability "Federal website scan results" (websites). You want to survey or filter the federal web estate - by agency, bureau, domain, liveness, redirect behaviour or analytics coverage - and read the actual scan records rather than a count. Example options: target_url_domain=nasa.gov, final_url_domain=nasa.gov, final_url_live=true. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "gsa-site-scanning" and capability "websites". 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>
