Why does it require an API key?

While the SEC and Treasury APIs do not require keys, the Census Bureau requires a free API key to handle the massive volume of hyper-local data (thousands of variables across millions of geographies). The key prevents rate limiting and ensures stable connections.

What geographies can I query?

This MCP limits the main built-in endpoints to State, County and Place (cities). Detailed geometries like zip-codes, tracts, or congressional districts can be queried utilizing the `query_census` custom tool.

Is Puerto Rico included?

Yes! Puerto Rico is treated internally as state FIPS code `72`.
