Overview
Short Code Generator works by randomly selecting characters from the specified character set to create codes of the desired length. Supports URL-safe character sets and excludes ambiguous characters in Base58 mode.

The tool
Once your client is connected to the VerveKit server, this appears in its tool list as ShortCodeGeneratorSkill. 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": "ShortCodeGeneratorSkill",
"arguments": {}
}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"
}
}
}https://api.vervekit.com/v1/mcpPer-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 |
|---|---|---|
countOptional | integer | Number of codes to generate default 1 · range 1–100 |
lengthOptional | integer | Length of each code default 8 · range 4–32 |
charsetOptional | string | Character setalphanumericalphanumerichexbase58default alphanumeric |
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": {
"codes": [
"bgiFznFh",
"jr84hHsG",
"Q77qABwn",
"gvMjXxXs",
"WDPJzCsi"
],
"count": 5,
"length": 8,
"charset": "alphanumeric",
"url_safe": true
}
}
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 |
|---|---|---|---|
codes | array | ["bgiFznFh","jr84hHsG","Q77qABwn"] | Array of generated short codes |
count | number | 5 | Number of codes generated |
length | number | 8 | Length of each generated code |
charset | string | alphanumeric | Character set used for generation |
url_safe | boolean | true | Whether the generated codes are safe to use in a URL without encoding |
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.
