How do I validate credit card / IMEI numbers with Luhn checksum via MCP?
intentvalidate-luhn-checksumconstraints
credential-freestdio transportnode runtime
I need to verify numbers using the Luhn (mod-10) algorithm — credit card numbers, IMEI codes, or any digit string that uses a Luhn check digit. I also want to compute the check digit for a partial number and complete an incomplete number by appending the correct check digit. Is there an MCP server that handles all three operations (verify, checksum, complete)?
