`compare_countries`

Pack: worldbank · Endpoint: https://gateway.pipeworx.io/worldbank/mcp

Compare a World Bank indicator across MULTIPLE countries in one call, returned ranked high→low. PREFER for “GDP per capita: US vs China vs Germany”, “rank the G7 by CO2 emissions”, “compare population of ”. Pass 2+ ISO country codes. Defaults to each country’s most-recent available value; pass a year for a specific year. Common indicators: NY.GDP.MKTP.CD (GDP), NY.GDP.PCAP.CD (GDP per capita), SP.POP.TOTL (population), EN.GHG.CO2.MT.CE.AR5 (CO2, Mt), FP.CPI.TOTL.ZG (inflation %). For CO2 rankings prefer country_co2_emissions, which knows the right series.
