Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

catalog Read-only

Inspect this connection’s scope, tools and access policy. With no arguments returns the usual catalog. On the general or economy connection, optionally supply report_countries (1–10 World Bank codes) for a FREE live preview of the optional paid country comparison: population/GDP/inflation by default, or up to six selected historical indicators over ten years, aligned JSON and CSV, definitions and source evidence. Preview reports price, missing cells, availability and the exact HTTP purchase path; it never signs or pays. Existing data tools remain free. Buying requires an authorized x402 HTTP client, not just MCP. Source/schema checks are not independent factual verification.

languagestring

Response metadata language, English by default or French; original source definitions and notes remain preserved.

report_tointeger

Inclusive last observation year, no later than the last completed calendar year. Supply with report_from and report_indicators; missing observations block purchase.

report_frominteger

Inclusive first observation year for a custom country preview. Supply with report_to and report_indicators; at most ten years, from 1960 onward.

report_countriesarray

Optional free preview for these distinct World Bank country codes, e.g. FRA, DEU, ESP. General/economy connections only.

report_indicatorsarray

Custom historical comparison: select up to six of the 22 WDI indicators. Supply report_from and report_to together, up to ten years. Missing cells block payment.

convert_currency_batch

Free pilot: convert dated decimal-string amounts to a target_currency chosen from 30 supported currencies, including EUR (default), USD, JPY, CNY, GBP, CHF, INR and KRW. Use exact-date ECB historical references; derived cross conversions use amount * target units per EUR / source units per EUR without intermediate rounding. Up to 500 rows, eight currency/year snapshots including target rates, 48,000 UTF-8 argument bytes; start small. Unique id per row. Half-even rounding by default, ISO 4217 minor-unit rounding per line: zero decimals for JPY/KRW/ISK, two for other supported targets; target_decimal_places reports precision; total_target sums rounded lines. amount_target is the result; legacy amount_eur/total_eur are null for non-EUR targets. Same-currency rows use identity without an external quote. Preserve originals and evidence for both currencies from the same source edition. Missing, stale or mismatched rates block complete export and total; never replace dates. JSON default; output_format=both includes CSV. ECB originals are free; indicative calculations are not executable prices or accounting/tax certification. No transfers, independent factual verification, customer-content retention or content logging.

Argument	Type	Description
rows*	array
rounding	string
output_format	string	json keeps the response smaller. both includes the CSV in the same free result; no separate export purchase.
