Automated State Demographics Checks

Use `get_demographics_by_state` to pull racial and ethnic data for every state. This is perfect for running nightly reports in a container or CI/CD pipeline. The output from the MCP Server can be piped directly into a shell script, allowing you to check compliance rules against demographic thresholds without needing any GUI.

County Population Scripting

Need population counts for specific counties? The `get_population_by_county` tool uses state FIPS codes (like CA=06) to get granular data. This is ideal for headless background jobs. You can write a simple shell script that loops through a list of required FIPS codes, calls the MCP Server function, and saves the JSON output into structured files.

National Population Metrics

The `get_population_by_state` tool gives total population and median age for all 50 U.S. states plus DC. This is your anchor point for national metrics. In a CI/CD context, you run this to validate that the latest census data aligns with expected range checks before deploying a service.
