Overview
Roman Numeral Converter works by converting numbers to Roman numerals using standard notation (I, V, X, L, C, D, M) or converting Roman numerals back to numbers. Supports numbers 1-3999 and validates Roman numeral syntax.
The tool
Once your client is connected to the VerveContext server, this appears in its tool list as RomanNumeralConversionforAIAgents. 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": "RomanNumeralConversionforAIAgents",
"arguments": {
"number": "2024"
}
}You do not name the tool yourself; the model picks it. Asking about 2024 in the terms this source covers is enough for it to reach for RomanNumeralConversionforAIAgents 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": {

}

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 |
|---|---|---|
numberRequired | integer | The number to convert to Roman numerals range 1–3999 |
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.
{
"status": "ok",
"error": null,
"data": {
"number": 2024,
"roman": "MMXXIV",
"breakdown": {
"M": 2,
"X": 2,
"IV": 1
}
}
}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 |
|---|---|---|---|
number | number | 2024 | The converted number from Roman numeral input |
roman | string | MMXXIV | The original Roman numeral provided for conversion |
breakdown | object | {…} | Object containing Roman numeral components and their counts |
breakdown.MPremium | number | 2 | Count of M (1000) symbols in breakdown |
breakdown.XPremium | number | 2 | Count of X (10) symbols in breakdown |
breakdown.IVPremium | number | 1 | Count of IV (4) subtractive pairs in breakdown |
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 roman: 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 1 credit each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.
