## MCP tools (2)

### `hnb_exchange_rates` (~163 tokens)

HNB (Croatian National Bank) official exchange rates for ALL foreign currencies on a given date. Croatia is in the eurozone, so every rate is quoted AGAINST THE EURO (units of foreign currency per 1 EUR). Returns rows with valuta (3-letter ISO code), srednji_tecaj (middle/reference rate), kupovni_tecaj (buying), prodajni_tecaj (selling), datum_primjene (apply date). Omit date for the latest applicable rates. Rate values are strings with a COMMA decimal separator (e.g. "1,164900").

Input parameters:

- `date` (string): Applicable date, YYYY-MM-DD, e.g. "2026-05-15". Omit for the latest applicable date.

### `hnb_currency_rate` (~212 tokens)

HNB exchange rate for ONE foreign currency vs EUR (Croatia is in the eurozone). Pass the 3-letter ISO currency code (e.g. "USD", "GBP", "CHF"). Three modes: omit dates for the latest rate; pass `date` for a single historical date; pass `start_date`+`end_date` for a daily time series over that window. srednji_tecaj is the middle/reference rate. Rate values are strings with a COMMA decimal separator (e.g. "1,164900"). Dates are YYYY-MM-DD.

Input parameters:

- `currency` (string, required): 3-letter ISO currency code, e.g. "USD", "GBP", "CHF".
- `date` (string): Single historical date, YYYY-MM-DD. Ignored if start_date is given.
