An MCP server that provides read-only U.S. Census ACS 5-year data for ZIP codes, including income, demographics, housing, education, and ZIP comparisons. It downloads Census data once into a local store and then serves lookups offline, with an extra reverse lookup tool for finding ZIPs within a place.
From the registry: U.S. Census (ACS) data by ZIP: income, demographics, housing, education, from a local store.
$ uvx mcpwright-census setupPlease install the `census-mcp` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **Install Python 3.12+** — Python 3.12 or newer is required to run the server via uvx.
- **Install uv/uvx** — The recommended portable install path uses uvx to run the published PyPI package.
- **Get a Census API key** — A free U.S. Census API key is required for the initial ACS dataset download. Set it as the CENSUS_API_KEY environment variable. (https://api.census.gov/data/key_signup.html)
- **Initialize the local data store** — Run the one-time setup to bulk-download the ACS dataset into the local store. The server can also download lazily on first use, but setup is the explicit recommended initialization step. Run: `uvx mcpwright-census setup`
Canonical MCP server config (stdio transport):
- command: `uvx`
- args: ["mcpwright-census"]
- required environment variables:
- `CENSUS_API_KEY`: Free U.S. Census API key used to download the ACS dataset for the local store. (example: `<your-census-api-key>`)
- optional environment variables:
- `CENSUS_MCP_STORE`: Optional override for the local store location where downloaded Census data is cached. (example: `<your-store-path>`)
Note: The server runs over stdio via the published PyPI package `mcpwright-census`. On first use it may lazily download the ACS dataset into a local SQLite store under the OS cache directory if setup was not run ahead of time. `uvx mcpwright-census refresh` re-downloads data when a new ACS vintage is published.
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.CENSUS_API_KEYrequiredFree U.S. Census API key used for the one-time ACS dataset download and refresh.CENSUS_MCP_STOREOverrides the local store location for downloaded Census data.Trending hip-hop artist momentum scores across four cultural dimensions.
