The tool

Once your client is connected to the VerveKit server, this appears in its tool list as CrosswordGeneratorSkill. 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": "CrosswordGeneratorSkill",
  "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"
    }
  }
}

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
`size`Optional	string	Grid size: small, medium, large `smallmediumlarge` default medium
`theme`Optional	string	Theme: random, animals, food, sports, science, geography `randomanimalsfoodsportssciencegeography` default random
`difficulty`Optional	string	Difficulty: easy, medium, hard `easymediumhard` default medium
`image`OptionalPremium	boolean	Set to true to generate a downloadable puzzle image
`solutionImage`OptionalPremium	boolean	Set to true to generate a downloadable solution 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 4 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.
