What is the USDA NASS MCP Server?
Connect to USDA NASS (National Agricultural Statistics Service) APIs through any AI agent and explore American agriculture data through natural conversation.
What you can do
- Crop Production — Query yield, production, harvested acres and price data for all major crops (corn, soybeans, wheat, cotton, rice)
- Livestock Data — Retrieve cattle inventory, hog production, poultry statistics, milk and egg production data
- Agricultural Economics — Access prices received/paid by farmers, farm income, production expenses and land values
- Farm Demographics — Explore Census of Agriculture data including operator age, experience, occupation and veteran status
- Parameter Discovery — Discover valid values for any filter parameter (commodities, states, years, units)
- Survey Metadata — Review information about all NASS surveys including frequencies and methodologies
How it works
- Subscribe to this server
- Enter your USDA NASS API Key (free at nass.usda.gov/developer)
- Start exploring agricultural data from Claude, Cursor, or any MCP-compatible client
No more navigating complex Quick Stats interfaces to find crop yields or livestock data. Your AI acts as a dedicated agricultural data analyst.
Who is this for?
- Agricultural Analysts — quickly query crop production data, compare yields across states and track price trends
- Farmers & Ranchers — check market prices, review production statistics and benchmark against state/national averages
- Researchers — access demographics data, survey methodologies and historical agricultural statistics for academic work
- Commodity Traders — monitor production volumes, inventory levels and economic indicators for market analysis
