GUID Generator Skill

Overview

GUID Generator works by creating random 128-bit identifiers following the RFC 4122 UUID version 4 specification. Supports multiple output formats including standard, uppercase, hyphen-less, and brace-enclosed.

The tool

Once your client is connected to the VerveKit server, this appears in its tool list as GUIDGeneratorSkill. 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": "GUIDGeneratorSkill",
  "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
`count`Optional	integer	Number of GUIDs to generate default 1 · range 1–100
`format`Optional	string	Output format `defaultuppercasenohyphensbraces` default default

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.

Result

{
  "status": "ok",
  "error": null,
  "data": {
    "guids": [
      "099FD1E4-60FD-4749-9B61-53A265F52579",
      "D68CA374-C822-40E4-9948-CE7A5D5FC76A",
      "F6DAD45F-A904-4007-89DF-8F5C76184910"
    ],
    "count": 3,
    "format": "uppercase",
    "version": 4,
    "variant": "RFC 4122"
  }
}

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
`guids`	array	`["099FD1E4-60FD-4749-9B61-53A265F52579","D68CA374-C822-40E4-9948-CE7A5D5FC76A","F6DAD45F-A904-4007-89DF-8F5C76184910"]`	Array of generated GUID strings in requested format
`count`	number	`3`	Total number of GUIDs generated in the response
`format`	string	`uppercase`	Output format applied to generated GUIDs
`version`Premium	number	`4`	UUID version used for GUID generation
`variant`Premium	string	`RFC 4122`	UUID variant standard followed by generated GUIDs

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.

Use cases

Database Records: Generate unique primary keys and identifiers for database records and entities
Session Management: Create unique session identifiers for web applications and APIs
File Naming: Generate unique filenames and resource identifiers to prevent conflicts
Transaction IDs: Create unique transaction and request identifiers for tracking and logging
