Best When

An agent needs to discover and access US federal government datasets from Data.gov — for policy research, academic analysis, or data journalism using publicly available government data.

Avoid When

You need real-time data, non-US government data, or commercial datasets.

Use Cases

  • Searching federal government datasets from research and policy agents
  • Finding economic indicators and census data from economics research agents
  • Accessing FDA, EPA, and USDA datasets from regulatory compliance agents
  • Discovering geospatial and climate datasets from environmental analysis agents
  • Retrieving public health data from epidemiology research agents
  • Building data pipelines from US government open data from analytics agents

Not For

  • Non-US government data (use country-specific open data portals)
  • Real-time data needs (Data.gov is primarily static datasets)
  • Commercial/proprietary data (Data.gov is exclusively public/open data)

Known Gotchas

  • Dataset discovery is the strength — actual data download requires following dataset-specific URLs
  • Data.gov catalogs metadata; actual data files hosted by individual agencies
  • File formats vary widely: CSV, JSON, XML, GIS, Excel — agents must handle diverse formats
  • Some datasets are outdated — check 'last updated' metadata before using
  • Metatool AI MCP — quality reflects organization's broader MCP ecosystem work
  • CKAN API pagination required for large result sets
