Summary
Generates UUIDs in multiple formats including v4, v7, ULID, and nanoid, with batch generation support. The server runs remotely via SSE transport and integrates x402 micropayments, meaning you'll pay fractional amounts per generation request. Reach for this when you need unique identifiers in your Claude workflows without spinning up your own generation logic. The batch support is handy if you're provisioning multiple resources at once and need a set of IDs in one call. The x402 integration means you're paying per use rather than running infrastructure, which makes sense for sporadic ID generation needs but adds cost overhead if you're generating thousands of identifiers regularly.

UUID Generator API
Generate UUID v4, v7, ULID, or nanoid identifiers. Batch up to 100 at once. Sortable, compact, or random formats. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
{
"mcpServers": {
"uuid-generator": {
"url": "https://uuid-generator.api.klymax402.com/mcp"
}
}
}
Quickstart -- HTTP (x402)
curl -X POST "https://uuid-generator.api.klymax402.com/api/generate" \
-H "Content-Type: application/json" \
-d '{}'
# -> 402 Payment Required, with an x402 payment challenge in the response body
Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

utility_generate_uuid
Use this when you need to generate unique identifiers for database records, API keys, or session tokens. Returns an array of IDs in the chosen format.
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
format | string | no | Format: uuidv4, uuidv7, ulid, nanoid (default: uuidv4) |
count | number | no | Number to generate (default: 1, max: 100) |
length | number | no | Length for nanoid (default: 21) |
Example response:
{"ids":["550e8400-e29b-41d4-a716-446655440000"],"format":"uuidv4","count":1}
When to use: creating primary keys, correlation IDs, or unique file names. Use uuidv7 or ulid WHEN you need time-sortable IDs for databases. Use nanoid FOR short URL-safe tokens.
Not for: hashing (use crypto_generate_hash), password generation (use security_check_password), slug generation (use text_generate_slug).
Example agent prompts
- "Generate unique identifiers for database records, API keys, or session tokens"
