Overview
Puzzles are built by trial. Each attempt draws two or three distinct vowels and fills the rest with distinct consonants to make seven letters, shuffles them and makes the first one the center letter. The API then finds every word in its common-word list that is at least four letters long, contains the center letter and uses only the seven letters, with repeats allowed. An attempt is accepted when that count falls in the target range for `difficulty`: 30-50 words for `easy`, 50-80 for `medium` and 80-150 for `hard`. After 100 attempts without a hit it uses the attempt with the most words, provided it found at least 20.
Scoring follows the familiar rules. A four-letter word scores 1 point and a longer word scores one point per letter. A pangram, a word that uses all seven letters at least once, earns 7 extra points. `maxPoints` is the sum over every valid word, `wordCount` is how many there are and `pangramCount` counts the pangrams. A pangram is not guaranteed, so `pangramCount` can be 0. `words` is sorted from highest to lowest points.
Letters are returned in uppercase. `allLetters` lists the center letter first, then the six `outerLetters` in their shuffled order. `difficulty` accepts only easy, medium or hard; any other value returns a 400 error.
Valid words come from that one list, so the answers can include words a hand-edited puzzle would leave out and miss some a player expects. On the Free plan `wordCount`, `pangramCount`, `maxPoints`, `words` and `html` are null and the `image` parameter is removed.

The tool
Once your client is connected to the VerveKit server, this appears in its tool list as SpellingBeeGeneratorSkill. 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": "SpellingBeeGeneratorSkill",
"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 |
|---|---|---|
difficultyOptional | string | Difficulty: easy, medium, hard (affects word count)easymediumharddefault medium |
imageOptionalPremium | boolean | Set to true to generate a downloadable puzzle image |
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.

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.
