Common questions

Is CurrencyFreaks safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: CURRENCYFREAKS_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 11 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

What's 50 USD in the local currency of IP 182.186.18.9?	`ip_to_currency`

Tool Reference

All 7 tools wrap the CurrencyFreaks v2.0 REST API. Tools that take symbols accept a comma-separated list of currency codes (e.g. EUR,GBP,PKR), case-insensitive. Use list_currencies to look up a code — there are 1000+ across fiat, crypto, and metals.

Precious metals use ISO 4217 codes: XAU (gold), XAG (silver), XPT (platinum), XPD (palladium). The API returns all rates and amounts as strings to preserve precision.

list_currencies

GET /v2.0/currency-symbols (compact) or GET /v2.0/supported-currencies (detailed) — the supported currency catalogue. No API key required.

Parameter	Required	Description
`search`	No	Case-insensitive substring matched against code, name, or (with `detailed`) country name, e.g. `rupee`, `PK`, `bitcoin`
`detailed`	No	`true` returns country, status (`AVAILABLE`/`DEPRECATED`), the `availableFrom`/`availableUntil` historical data range, and flag icon per currency. Default `false`. Combine with `search`; the full detailed catalogue is ~270 KB.

get_latest_rates

GET /v2.0/rates/latest — latest rates for one or more currencies against a base. Refresh frequency depends on plan: daily on Developer (free), hourly on Starter, every 10 minutes on Growth, every 60 seconds on Professional and above.

Parameter	Required	Description
`symbols`	No	Comma-separated currency codes. Omit for all 1000+ currencies.
`base`	No	Base currency code. Default `USD`. Paid plans only.

convert_currency

GET /v2.0/convert/latest, or GET /v2.0/convert/historical when date is given — convert an amount between two currencies. Paid plans only.

Parameter	Required	Description
`from`	Yes	Currency code to convert from
`to`	Yes	Currency code to convert to
`amount`	No	Amount to convert, greater than 0. Default `1.0`.
`date`	No	`YYYY-MM-DD`. Converts at that day's rate instead of the latest.

get_historical_rates

GET /v2.0/rates/historical — rates on a specific past date. Major fiat currencies go back to 1984-11-28; newer currencies and crypto start from their own listing date. Paid plans only.

Parameter	Required	Description
`date`	Yes	`YYYY-MM-DD`
`symbols`	No	Comma-separated currency codes. Omit for all.
`base`	No	Base currency code. Default `USD`.

get_time_series

GET /v2.0/timeseries — daily rates between two dates, one entry per day. Professional plan and above.

Parameter	Required	Description
`startDate`	Yes	`YYYY-MM-DD`
`endDate`	Yes	`YYYY-MM-DD`
`symbols`	No	Comma-separated currency codes
`base`	No	Base currency code. Default `USD`.

get_fluctuation

GET /v2.0/fluctuation — how each currency moved between two dates: start rate, end rate, absolute change, and percent change. Professional plan and above.

Sign convention: change is startRate - endRate. A positive change means the rate fell (the symbol currency strengthened against the base); a negative change means the rate rose (the symbol currency weakened).

Parameter	Required	Description
`startDate`	Yes	`YYYY-MM-DD`
`endDate`	No	`YYYY-MM-DD`. Defaults to the day before today.
`symbols`	No	Comma-separated currency codes
`base`	No	Base currency code. Default `USD`.

ip_to_currency

GET /v2.0/iptocurrency — resolves the local currency from an IP address's geolocation and converts an amount into it. The target currency comes back in the to field. Growth plan and above.

Parameter	Required	Description
`from`	Yes	Currency code to convert from
`ip`	No	IPv4 or IPv6 address. Omit to use the caller's own IP.
`amount`	No	Amount to convert. Default `1.0`.

Plan Requirements

Feature	Minimum plan
`list_currencies`	None (no API key needed)
`get_latest_rates` with default USD base	Developer (free)
`base` parameter on any tool	Starter
`convert_currency`	Starter
`get_historical_rates`	Starter
`ip_to_currency`	Growth
`get_time_series`	Professional
`get_fluctuation`	Professional
