Slot Machine Skill

The tool

Slot Machine Simulator provides authentic slot machine experience with weighted symbol probabilities, configurable reels (3-5), payout multipliers, and comprehensive statistics including net profit and win percentages.

Once your client is connected to the VerveKit MCP server, this appears in its tool list as SlotMachineSkill. It is read-only and open-world: it fetches, it never mutates anything on your side, so most clients will call it without asking you to confirm.

{
  "name": "SlotMachineSkill",
  "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 Desktop, 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.

What the model gets back

The result carries a structuredContent object matching the tool's declared outputSchema, so a client can read fields without parsing prose. status is "ok" on success and error is null; a null field means the value wasn't available for that input, not that the call failed.

Errors come back as tool errors with a sentence the model can act on, not a bare status code.
