Currency Symbol Grounding Data

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 VerveContext server, this appears in its tool list as CurrencySymbolGroundingData. 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": "CurrencySymbolGroundingData",
  "arguments": {
    "currency": "USD"
  }
}

You do not name the tool yourself; the model picks it. Asking about USD in the terms this source covers is enough for it to reach for CurrencySymbolGroundingData on its own — naming it explicitly also works, and is the way to force the call.

Connecting

One server URL covers every source 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": {
    "vervecontext": {
      "url": "https://api.vervecontext.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
`currency`Required	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_name`Premium	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_number`Premium	string	`840`	ISO 4217 numeric currency code
`countriesFound.0.currency_mnr_unts`Premium	string	`2`	Minor currency units for decimal place specification
`countriesFound.0.currency_symbol`Premium	string	`$`	Symbol representing the currency
`currency`	string	`USD`	The currency code of the queried country

Why ground on it

A model can produce something that looks like this answer from its training data, and be confidently out of date or simply wrong. This source returns the current value in a shape you can check, which is the difference between an answer you can cite and one you have to hedge.

Point an evaluation at countriesFound.0.country_name: it is the field most worth pinning a claim to, and it is either present and current or absent — never plausibly invented.

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 source is not part of VerveContext. 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.

Use cases

E-Commerce Storefronts: Look up a buyer's country during checkout to retrieve the matching ISO currency code and render localized pricing with the correct symbol.
Invoicing Systems: Accounting platforms query an ISO currency code to identify the associated countries, numeric code, and decimal precision before generating international billing records.
Multi-Currency Digital Wallets: When a customer opens a foreign account balance, fetch the official currency name and symbol to display next to the ledger balance.
Expense Report Processing: Map foreign transaction entries to their originating country and currency code to validate expense submissions across international subsidiaries.
