Overview
Currency Symbols works by querying a large currency database to retrieve the symbol and name of a currency. It returns the currency data in a structured format.

The tool
Once your client is connected to the VerveKit server, this appears in its tool list as CurrencySymbolSkill. It is read-only and open-world — it fetches and never mutates anything on your side — so most clients call it without asking you to confirm.
{
"name": "CurrencySymbolSkill",
"arguments": {
"currency": "USD"
}
}You do not name the tool yourself; the model picks it. Asking about USD in the terms this skill covers is enough for it to reach for CurrencySymbolSkill on its own — naming it explicitly also works, and is the way to force the call.
Connecting
One server URL covers every skill in the catalog, including this one. Authorization is OAuth: the client opens a browser once, and there is no key to paste into a config file.
{
"mcpServers": {
"vervekit": {
"url": "https://api.vervekit.com/v1/mcp"
}
}

Arguments
These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made. Premium arguments are accepted on every plan but only take effect on plans that include them.
| Argument | Type | Description |
|---|---|---|
currencyRequired | string | The currency code for which you want to get the symbol |
What the model gets back
The result carries a structuredContent object matching the tool's declared outputSchema, so a client reads fields without parsing prose. status is "ok" and error is null on success; a null field means the value was not available for that input, not that the call failed.

Response fields
Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.
| Field | Type | Example | Description |
|---|---|---|---|
countriesFound | array[19] | Array of countries matching the search query | |
countriesFound.0.country_name | string | AMERICAN SAMOA | Full name of the country |
countriesFound.0.currency_namePremium | string | US Dollar | Full name of the currency used in country |
countriesFound.0.currency_iso_code | string | USD | ISO 4217 currency code for the country |
countriesFound.0.currency_numberPremium | string | 840 | ISO 4217 numeric currency code |
countriesFound.0.currency_mnr_untsPremium | string | 2 | Minor currency units for decimal place specification |
countriesFound.0.currency_symbolPremium | string | $ | Symbol representing the currency |
currency | string | USD | The currency code of the queried country |
Failure modes
Errors come back as tool errors carrying a sentence the model can act on, not a bare status code. Error handling covers the full list.
| Status | What it means |
|---|---|
400 / 422 | The arguments did not validate. The message names the offending one. |
401 | The OAuth session is invalid or expired — reconnect the server. |
403 | Blocked by a key restriction or an IP allow-list. Never a bad identity. |
404 | This skill is not part of VerveKit. Check the catalog. |
429 | Out of credits, or a brief rate limit. The message tells them apart. |
A call costs 2 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.
