Team-wide SNAP merchant lookups

The `search_retailers` tool allows your team to query the USDA public database directly from VS Code Copilot Chat using this MCP server. By committing the configuration to your repository, every developer gets instant access to the same live merchant data. This setup keeps your team aligned when building features for SNAP beneficiaries. Developers can verify store names and zip codes without leaving their code files.

Coordinate-based testing via this MCP Server

The `search_retailers_by_location` tool lets your agent run coordinate searches during active coding sessions. You can write your geolocation filters and immediately test them against real-world USDA coordinates. Copilot uses the live API responses to write accurate integration tests. You don't have to manually write mock JSON files for different radius parameters.

Clean data modeling with live schemas

The `search_retailers` tool retrieves active merchant listings, giving your agent the exact schema of the USDA public data. This helps you design database migrations and TypeScript interfaces that match the actual API output. Your agent inspects the returned fields to ensure your code handles null values or missing address lines correctly. It prevents runtime errors when you deploy your application.
