Hosted cost-of-living calculator that exposes six MCP tools for comparing cities across 69 countries. You get take-home pay after taxes, rent and groceries breakdowns, equivalent salary math, and quantified safety-net deltas like parental leave, vacation days, and universal healthcare. Use compare_cities for full scenario analysis, rank_cities to filter by composite quality scores, or get_inbound_tax_regime to check expat programs like Italy's impatriati or Portugal's IFICI. Free tier, no API key, rate-limited at the edge. Built on Streamable HTTP so Claude Desktop, Cursor, and ChatGPT Desktop connect with one JSON line. Ships an optional stdio bridge for older clients.
