Map SNAP retailers from Claude Desktop

The `search_retailers_by_location` tool lets your agent find SNAP-authorized stores within a specific mile radius of any GPS coordinates. You don't have to look up coordinates manually or leave your chat window to find where people can use their benefits. Just type a lat-long pair and let your AI client fetch the exact list of stores. Running this MCP server as a local subprocess pulls data directly into your active workspace.

Run detailed store queries using this MCP Server

The `search_retailers` tool lets your AI client filter the entire USDA database by store name, city, state, and zip code. You can quickly verify if a specific grocer accepts SNAP benefits without hunting through stale government PDFs. Your agent handles the API calls directly through the desktop configuration. It formats the raw JSON response into a clean list right inside your chat window.

Quick local lookups for regional data

The `search_retailers` tool targets specific locations like state 'VA' and zip '22314' to pull active merchant lists instantly. Claude Desktop processes these queries locally, keeping your regional research fast and self-contained. Because this MCP server runs as a local subprocess, you get fast response times when querying large datasets. Your agent handles the heavy lifting of parsing the USDA public registry.
