FAQ from cityparity: Cost-of-Living & Quality-of-Life Comparison
How is this different from other cost-of-living calculators?
cityparity explicitly prices the social safety net (childcare subsidies, parental leave, statutory vacation, universal healthcare) so that "the lower-salary city actually pays more" becomes a quantifiable number.
What are the runtime or dependency requirements?
The hosted MCP server has no client-side dependencies. The optional npm bridge (cityparity-mcp) requires Node.js ≥ 20 and uses no external dependencies.
Where does my query data go?
Queries are sent only to mcp.cityparity.com. No accounts, no client-side telemetry, and no personally identifiable information is logged beyond standard HTTP server logs.
Are there any known limits or restrictions?
The service is rate-limited at the edge. RSU income is not supported as an input; grants are treated as source-only because they generally do not follow you across employers.
What transport and authentication are used?
The server speaks Streamable HTTP (MCP spec 2025-06-18). It is completely free and requires no API key or authentication.
