Tools

• worldbank_get_country

  Fetches full metadata for a specific country or aggregate entity: region, income level, capital, coordinates, and lending type. Accepts ISO2 codes (US, DE), ISO3 codes (USA, DEU), or World Bank aggregate codes (EAS, HIC, WLD).

  shallow
• worldbank_get_data

  Queries World Bank indicator values for one or more countries across a time range. The primary data-access tool — use worldbank_search_indicators to find indicator_id values. Returns observations with null values when data is not available for a country×year cell (common for sparse series). Specify either date_range (historical analysis) or mrv (most recent N values), not both. For "all" countries, use pagination (per_page up to 1000) — the API returns several hundred entries per indicator.

  shallow
• worldbank_get_indicator

  Fetches complete metadata for a single World Bank indicator by its ID: name, description, source dataset, source organization, unit, and thematic topics. Use worldbank_search_indicators to discover indicator IDs if you only know the concept.

  shallow
• worldbank_get_poverty

  Queries poverty and inequality estimates from the World Bank Poverty and Inequality Platform (PIP) for one or more countries. Returns the poverty headcount ratio, poverty gap, and poverty severity at any poverty line, plus mean and median welfare and population. This is also the tool for inequality and distribution questions — survey-based rows carry the Gini coefficient, mean log deviation, polarization, and the ten decile income/consumption shares, because PIP returns poverty and inequality in the same row. PIP is a separate dataset from the WDI series worldbank_get_data reads: it measures welfare in PPP dollars per person per day and covers individual economies only, so regional and income-group aggregate codes are not accepted. Every row reports how it was produced. estimationType "survey" rows carry the full inequality block; "interpolation", "extrapolation", and "CMD estimation" rows are gap-filled estimates for years no survey covers, and their gini, mld, polarization, and decileShares are null — a documented gap in the source data, not an error.

  shallow
• worldbank_list_countries

  Lists countries and regional aggregates with metadata: ISO codes, region, income level, capital, and coordinates. Filterable by region code (e.g. EAS, SSF, NAC) and income level (LIC, LMC, UMC, HIC). By default, excludes regional/income-group aggregate entries and returns individual countries only. Set include_aggregates=true to also see region, income group, and world aggregate entities.

  shallow
• worldbank_list_sources

  Lists the 70+ World Bank data sources (datasets) such as World Development Indicators, IDS, and Doing Business. Returns source IDs and names for use as source_id in worldbank_search_indicators. Supports pagination.

  shallow
• worldbank_list_topics

  Lists all 21 World Bank thematic topics (Economy & Growth, Health, Education, etc.) with descriptions. Use to browse the indicator space or find a topic_id for worldbank_search_indicators.

  shallow
• worldbank_search_indicators

  Searches the 29,500+ World Bank indicator catalog by keyword, topic, or source. Returns indicator IDs and metadata for chaining into worldbank_get_data. At least one of query, topic_id, or source_id must be provided. A keyword query matches every term against indicator ID, name, and description, in any word order, across the whole catalog or the whole selected topic or source; punctuation in the query is ignored. Exact ID or name matches rank first, then whole-phrase matches, then ID/name matches, then description-only matches. Each indicator ID appears once, even where the catalog publishes it under two sources. Use worldbank_list_topics for topic IDs, worldbank_list_sources for source IDs.

  shallow
• worldbank_search_projects

  Searches the World Bank lending portfolio — the individual loans, credits, and grants the Bank finances — by free text, country, region, status, and board approval date. Returns the project ID, name, borrowing country, region, status, board approval and closing dates, total commitment in USD, financing instrument, major sectors, and a link to the project page. This is the operations catalogue, not the statistics catalogue: use it for "what is the World Bank funding in Kenya", "which climate adaptation projects are active", or "how much was committed to education in South Asia since 2020". For development statistics and time series, use worldbank_search_indicators and worldbank_get_data instead. Countries are identified by ISO2 code here (BR, IN, ZA), which is the one place this server departs from the ISO3 codes its other tools take — worldbank_get_country reports a country's iso2 field for either form, and multi-country operations carry a World Bank regional code such as 3A instead. Every filter is an exact match upstream and combines with the others by AND, so a narrow search can legitimately return nothing; when it does, the response says whether the country codes matched anything on their own.
