Overview
Words to Numbers works by converting words to numbers using a predefined set of rules. It supports a wide range of words and provides the equivalent numbers in a structured format.

The tool
Once your client is connected to the VerveKit server, this appears in its tool list as WordstoNumbersSkill. 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": "WordstoNumbersSkill",
"arguments": {
"words": "seven thousand six hundred and twenty"
}
}You do not name the tool yourself; the model picks it. Asking about seven thousand six hundred and twenty in the terms this skill covers is enough for it to reach for WordstoNumbersSkill 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 |
|---|---|---|
wordsRequired | string | The words to convert to numbers |
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": "7620",
"words": "seven thousand, six hundred twenty",
"ordinal": "seven thousand, six hundred twentieth",
"numberOfDigits_numeric": 4,
"numberOfDigits_words": "four",
"eachNumber": [
"seven",
"six",
"two",
"zero"
]
}
}
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 | string | 7620 | Numeric representation of the input words |
words | string | seven thousand, six hundred twenty | Original words formatted in standard English notation |
ordinalPremium | string | seven thousand, six hundred twentieth | Ordinal form of the number in words |
numberOfDigits_numeric | number | 4 | Count of individual digits in the number |
numberOfDigits_words | string | four | Digit count expressed in words format |
eachNumberPremium | array | ["seven","six","two"] | Array with each digit represented as a word |
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.
