Converts amounts between ECB-quoted currencies using official daily reference rates. Handles single conversions, batch conversions across multiple currencies, and historical rate lookups. Useful for invoicing, expense tracking and multi-currency transactions.

Example request: "Convert 500 EUR to USD using today's ECB rate for an invoice."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Currency Exchange to help me. It is a free service with an MCP server at https://mcp.zovo.one/mcp/currency-exchange. It needs an API key from theluckystrike; ask me to enter it through your secure credential prompt. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- rates_latest: Call this tool for the latest ECB daily reference rates against any base: 1.0812 for USD means 1 base = 1.0812 USD. Crosses go through the euro. Returns the ECB rate date and the cache age.
- convert: Call this tool to convert an amount between any two ECB-quoted currencies, today or on a past date. Returns the converted amount, the cross rate to 6 decimals, the rounding applied and the rate date used.
- convert_many: Convert one amount into many currencies off the SAME ECB rate date, each rounded to its own minor units. For several lines at once (mixed-currency invoice lines), call it once per line: every line then shares one rate date. Unknown targets are listed, never failed.
- fx_rates_for: Call this tool when a rebill or an invoice spans more than one currency, instead of asking the user for rates. Returns the fx_rates object expense_to_invoice takes, plus the rate date to write on the invoice.
- rate_history: Call this tool for the ECB rate of one currency pair across a window. Returns one row per published day plus the min, max, average and the change. A window wider than the free 90 days is shortened, not refused.
- rate_on: Call this tool for the ECB rate of one pair on one date. Returns both directions and the rate date, so a reciprocal is never reported as the published figure. A date beyond the free window is shortened, never refused.
- currencies_list: Every currency in the ECB daily set with its rate against the euro and its decimal places. This is the whole domain: a code not on this list cannot be converted, quoted or historised here.
- cache_status: Report the ECB rate cache here: which dates are held, how old they are and when they refresh. Reads only. Check it before trusting a rate after time offline; a cache that no longer parses is quarantined and named.
- license_status: Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.
- license_activate: Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
