Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

exchange

get_exchange_rate_history

ECB historical daily reference rates for one currency against EUR. Provide year (1999 onward) or an exact date, not both. Default: current year. Returns one year at most, original decimals, missing values and evidence. No weekend carry-forward, interpolation, current quote for discontinued currencies, cross rates or executable prices.

get_exchange_rates

ECB indicative daily currency reference rates against EUR. Not real-time or executable prices; inspect observation_date. Original rates freely available at the cited ECB source.

list_exchange_rate_history

List available currencies, annual snapshots since 1999 and explicit gaps in ECB daily reference FX history. Some currencies have been discontinued. Units per EUR; original data freely available at ECB.

catalog

catalog

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.

convert

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 Use exact-date ECB historical references; derived cross conversions use amount * target units per EUR / source units per EUR without intermediate rounding.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.

evidence

get_evidence

Retrieve the source JSON snapshot and SHA-256 digest for a currently available record. The digest proves snapshot integrity, not factual truth.

record

get_record

Get an unexpired record with provenance and its explicit verification level. Source/schema validation is not independent factual verification.
