Overview

AI-generated overview

Remote MCP endpoint that generates UUID v4/v7, ULID and nanoid identifiers in batches, paid per call with USDC micropayments.

What you can do
  • Generate unique identifiers in uuidv4, uuidv7, ulid or nanoid format
  • Request batches of up to 100 IDs at once, with a configurable nanoid length
  • Receive the generated IDs as an array in the chosen format
When to use it
Useful when an assistant needs fresh unique IDs for database primary keys, correlation IDs, session tokens or file names, especially time-sortable uuidv7/ulid values. It is a narrow single-purpose service, so it only makes sense if you already accept pay-per-call crypto payments.
Requirements
A remote MCP client pointed at the hosted endpoint; nothing to install locally. No API key or signup, but each call is paid in USDC on the Base L2 network through the x402 protocol, so an x402-capable client and a funded wallet are needed. Network access to the provider's host.
Before you install
Every call costs money ($0.003 per generate call) in USDC on Base, settled through a crypto wallet, so an assistant could spend funds without a clear per-call prompt. Payment handling depends on the client's x402 support. Generated identifiers come from a third-party service, so they should not be treated as secret or used for security-sensitive tokens.

Installation

In SourceWeft

  1. Open UUID Generator API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Br0ski777%2Fuuid-generator/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

UUID Generator API

[MCP Server] [x402] [License: MIT]

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.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "uuid-generator": {      "url": "https://uuid-generator.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
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.

Tools

ToolMethodPathPriceDescription
utility_generate_uuidPOST/api/generate$0.003Generate unique identifiers

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

NameTypeRequiredDescription
formatstringnoFormat: uuidv4, uuidv7, ulid, nanoid (default: uuidv4)
countnumbernoNumber to generate (default: 1, max: 100)
lengthnumbernoLength for nanoid (default: 21)

Example response:

json
{"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"

Payment

  • Protocol: x402 -- HTTP-native pay-per-call, no signup, no API key

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
