Overview

What is mcp-census?

mcp-census is a proof of concept for an MCP (Model Context Protocol) server that delivers Census Bureau 2020 decennial data for AI Agent interoperability. It is intended for developers building AI agents that need to access U.S. census data via the MCP protocol.

How to use mcp-census?

The server requires two API keys: CENSUS_API_KEY (request at https://api.census.gov/data/key_signup.html) and GEMINI_API_KEY (request at https://ai.google.dev/gemini-api/docs/api-key). To run the MCP server, execute uv run python mcp_server/app.py. An accompanying agent can be run with uv run python app.py.
