Currency Conversion Skill

Overview

Currency Converter works by analyzing the amount and currency provided and converting the currency rate. It uses advanced algorithms to convert the currency rate based on the amount and currency and returns the converted currency rate.

The tool

Once your client is connected to the VerveKit server, this appears in its tool list as CurrencyConversionSkill. 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.

Tool call

{
  "name": "CurrencyConversionSkill",
  "arguments": {
    "value": "1",
    "from": "USD",
    "to": "EUR"
  }
}

You do not name the tool yourself; the model picks it. Asking about 1 in the terms this skill covers is enough for it to reach for CurrencyConversionSkill 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"
    }
  }
}

Per-client setup — Claude, Cursor, VS Code, ChatGPT — is on the MCP setup page.

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
`value`Required	number	The amount to convert range 0–∞
`from`Required	string	The ISO 4217 currency code to convert from
`to`Required	string	The ISO 4217 currency code to convert to

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.

Result

{
  "status": "ok",
  "error": null,
  "data": {
    "from": "USD",
    "to": "EUR",
    "value": 1,
    "convertedValue": 0.921456,
    "rate": 0.921456,
    "change24h": -0.002134,
    "change24hPct": -0.2312,
    "changeDirection": "down",
    "high24h": 0.924521,
    "low24h": 0.919823
  }
}

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
`from`	string	`USD`	Source currency code (e.g., USD, EUR)
`to`	string	`EUR`	Target currency code (e.g., USD, EUR)
`value`	number	`1`	Original amount to convert
`convertedValue`	number	`0.921456`	Converted amount in target currency
`rate`	number	`0.921456`	Current exchange rate for the currency pair
`change24h`Premium	number	`-0.002134`	Rate change vs 24 hours ago
`change24hPct`Premium	number	`-0.2312`	Percentage rate change vs 24 hours ago
`changeDirection`	string	`down`	Direction of 24h change: up, down, or unchanged
`high24h`Premium	number	`0.924521`	Highest rate in the past 24 hours
`low24h`Premium	number	`0.919823`	Lowest rate in the past 24 hours

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.
