More Details Connect to Claude

Connect to the Data.gov Catalog to explore the comprehensive repository of US Government open data. This MCP server allows AI agents to discover datasets from agencies like NASA, NOAA, and the Census Bureau through natural language.

What you can do

  • Dataset Discovery — Search the entire catalog using keywords, organization filters, and advanced sorting via search_datasets.
  • Spatial Analysis — Find datasets by geographic location using GeoJSON boundaries and spatial filters with search_locations and get_location_geometry.
  • Organization Insights — List all publishing organizations and filter results by specific agency slugs using get_organizations.
  • Metadata Inspection — Retrieve detailed harvest records, including raw and transformed DCAT-US payloads with get_harvest_record_raw and get_harvest_record_transformed.
  • Keyword Trends — Analyze commonly used keywords and their dataset counts to identify data trends using get_keywords.

How it works

  1. Subscribe to this server
  2. Enter 'PUBLIC' or your API key if required by your proxy
  3. Start querying the US Government's open data repository directly from Claude, Cursor, or any MCP-compatible client

Who is this for?

  • Data Scientists — quickly find relevant datasets for analysis without manual browsing
  • Researchers — access official government metadata and harvest records for academic or policy work
  • Developers — integrate public data sources into applications using structured GeoJSON and DCAT-US metadata

Search for NASA datasets related to climate change.

I found several NASA datasets. Notable results include 'Global Surface Temperature Analysis' and 'Climate Model Outputs'. Would you like the full metadata for any of these?

List all government organizations that publish data here.

I've retrieved the list of publishing organizations. There are over 1,200 entities, including major agencies like NOAA, NASA, and the Department of Education. Which one would you like to explore?

Get the GeoJSON boundary for 'Los Angeles' to filter my search.

I've found the location ID for Los Angeles. Retrieving the GeoJSON geometry now... Done. You can now use this boundary to filter datasets using the `search_datasets` tool.

Yes! Use `search_locations` to find a location ID, then `get_location_geometry` to get the GeoJSON. Finally, pass that to `search_datasets` with the `spatial_geometry` parameter.
