Tools of exchange-rates-mcp-server
	Description		Read-only	Idempotent	Open world
`fx_convert_currency`Convert an amount between any two currencies at the latest or a historical rate. Returns the converted amount, the rate used, the actual rate date, and whether the date was snapped from a weekend/holiday to the prior business day. Cross-rates are triangulated through EUR automatically.	Convert an amount between any two currencies at the latest or a historical rate.

Cross-rates are triangulated through EUR automatically.	Not declared	Yes	Yes	Yes
`fx_dataframe_describe`List tables and columns staged on a DataCanvas from a prior fx_get_timeseries call. Required first step before fx_dataframe_query — use it to discover table names and column schemas. Requires DataCanvas, which is on by default — a deployment that turns it off does not list this tool at all, and fx_get_timeseries returns every range inline there.

`fx_dataframe_query`Run a read-only SQL SELECT against DataCanvas tables staged by fx_get_timeseries. Supports aggregations, GROUP BY, window functions, and JOINs across multiple registered tables. Run fx_dataframe_describe first to discover table names and column schemas.

`fx_get_rate`Get the exchange rate for a currency pair on a given date (default: latest). Returns the rate, the actual rate date (which may differ from the requested date on weekends/holidays — daily observations may skip non-publication days), and source provenance. Cross-rates are triangulated through EUR automatically. A same-currency pair returns a rate of 1, dated to the same publication day any other pair would report for that date. Use fx_convert_currency when you want the converted amount; use this tool when you only need the rate number.	Get the exchange rate for a currency pair on a given date (default: latest).

`fx_get_rates`Get all available exchange rates for one base currency in a single snapshot. Useful for bulk comparison and seeding downstream tools. Returns a map of quote currency → rate, the actual snapshot date, and whether a historical date was snapped from a weekend/holiday to the prior business day. Optionally filter to a subset of quote currencies via symbols. Listing the base currency itself in symbols is accepted and returns a rate of 1 for it.

`fx_get_timeseries`Get historical daily Frankfurter v1 rates over an inclusive date range. Same-date EUR legs are divided without intermediate rounding; only days with both currencies appear, including observed self-pairs at 1 and historical retired currencies. Missing-leg served days produce coverage notices; weekends and holidays are not counted as missing. summary covers all observed days before delivery: arithmetic mean, earliest tied extrema, endpoints and percentage change, without accounting policy. limit bounds returned rows (default/max 500); 0 returns summary only. Continue inline with next_start_date, the same end_date and a positive limit. Long ranges (>90 days by default) stage beyond the 40,000-character preview budget, independently of limit. Explicit canvas_id always stages the complete series, including short/empty results, and fails if unavailable or unknown. Each registration preserves earlier tables with a unique table_name. spilled=true returns canvas_id and table_name; use fx_dataframe_describe then fx_dataframe_query for SQL. Without DataCanvas, omit canvas_id to page inline.	Get historical daily Frankfurter v1 rates over an inclusive date range.

`fx_list_currencies`List current Frankfurter v1 currency codes and names with as_of, the latest served rate date. include_retired=true adds historical codes absent from the current set. Optional official ECB start_date/end_date are outer coverage bounds, not uninterrupted availability; a dated end_date does not imply retirement. Metadata outages are disclosed without failing current discovery. Historical availability remains validated from requested v1 data. Use this to disambiguate dollars (USD vs AUD vs CAD).
