Calculate distances using MCP Server

Need to know how far apart two locations are? Just use `get_zip_distance` to calculate the mileage between any two ZIP codes. You pass in two pairs of codes, and it spits out the exact distance. This is perfect for auditing supply chains or validating regional sales territories. It gives you a concrete metric—the miles—not just an estimate.

Find all locations by state

When you need to scope out a whole region, start with `find_zips_by_state`. Drop in the state abbreviation, and it returns every corresponding ZIP code. You'll get a massive list of data points instantly. This saves you from manually cross-referencing spreadsheets or dealing with partial datasets.

Get detailed records for any ZIP Code

Don't just know the code; know what it means. `get_zip_details` pulls geographic and demographic data for a specific ZIP code. You get more than just coordinates—you get the context. Use this to enrich your database entries or quickly verify if a location matches expected census parameters.
