Convert and checksum a batch of identifiers

Generate deterministic UUIDs for a batch of records, CRC-32 checksum them, then Luhn-validate any card-like numbers involved.

Workflow

Step 1 of 3

Deterministic UUID (v5 / v3)

Generate a deterministic UUID for each record from a namespace and name.

uuid5({"name": "example"})

Step 2 of 3

CRC-32 / Adler-32 Checksum

CRC-32 checksum the resulting identifier batch.

crc32({"text": "hello from an agent"})

Step 3 of 3

Luhn Checksum (validate / check digit)

Luhn-validate any card-like check-digit numbers in the same batch.

luhn({"number": "example"})

Install

One command wires up every tool below for Claude Code:

claude mcp add --transport http wingman https://wingmanprotocol.com/mcp

Claude Desktop, Cursor and Continue configs are on /install. A free key (500 calls/month, no card) is on /pricing; beyond that it is x402 pay-per-call in USDC on Base.
