Overview
The MCP Server provides a standardized API for AI assistants (LLMs) to access and process U.S. Census Bureau data and geography information, enabling data retrieval and analysis through an agent-like interface.
Installation
npm run prod:buildEnvironment Variables
- CENSUS_API_KEY
- DATABASE_URL
- DEBUG_LOGS
- SEED_MODE
Security Notes
The server uses environment variables for sensitive data like `CENSUS_API_KEY` and `DATABASE_URL`, which is good practice. Input validation is implemented using `zod` schemas. Database interactions largely use parameterized queries, which mitigates common SQL injection risks. However, the `recordApiCall` and `hasApiBeenCalled` functions directly interpolate the `url` parameter into SQL queries. While `url` is typically constructed internally from trusted Census API endpoints, this pattern could pose a risk if malicious user input could somehow manipulate this variable without prior sanitization.
