    How to connect

    How to connect exchangerate.dev to Claude

    The server address to paste into Claude settings:

    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Server tool list (7)

    Raw names from tools/list. Only developers need these.

    start_checkoutOpen a billing URL for an explicitly selected eligible plan. After human confirmation, a Free account without a subscription receives a one-hour Stripe Checkout URL; an existing Basic subscriber receives Stripe billing management instead. Cancellation creates nothing and account identifiers are never accepted from the model.
    list_currenciesList all supported currencies with name, decimal precision, minor units, and whether the pair is derived (triangulated). Use this before other tools to discover valid currency codes.
    get_usd_indexGet the latest independently calculated USD index. dxy-reconstructed uses the published six-currency basket formula but is not official or licensed ICE data. usd-strength is the versioned exchangerate.dev equal-weight 13-currency index, with 2026-01-02 = 100. Both require a complete, time-aligned basket.
    get_rateGet the current — or historical, with date — exchange rate from one currency to another. Indicative developer-grade reference rates (aggregated market data + public reference rates), not for settlement or trading. Rates update ~60s for real-time currencies through the trading week when the live overlay is active; the source field on every response is the authoritative freshness indicator (live | ecb_daily | fred_daily | nbp_daily) — rates fall back to official daily reference data during market closures, data-source unavailability, or low liquidity. market_session on every response indicates open, weekend, or interbank_closed.
    convertConvert an amount from one currency to another at the current rate. Indicative developer-grade reference rates (aggregated market data + public reference rates), not for settlement or trading.
    get_rangeGet a daily time-series of exchange rates over a date range (business days). Capped at 366 rows per call; when has_more is true, pass next_cursor as the cursor parameter to fetch the next page. Indicative developer-grade reference rates (aggregated market data + public reference rates), not for settlement or trading.
    search_docsSearch the exchangerate.dev FAQ corpus via BM25. Returns the top-K matching questions and answers with relevance scores. Use before answering how-to / pricing / data-sourcing questions so you cite the canonical text instead of guessing from training data.
