Run Modulus 97 checks locally in Claude Desktop

The `validate_iban` tool is your direct line to verifying international account numbers inside Claude Desktop. You are about to run a wire transfer and need to make sure the destination account actually exists. Instead of copying strings into sketchy web forms, let your agent do the math. No external APIs or cloud dependencies are needed for this to work. Standard Modulus 97 arithmetic catches typos before they cost you a hundred bucks in bank fees. The tool simply checks the structure and tells you if it's safe to send.

Stop wire transfer failures before they happen

By calling the `validate_iban` tool, you can check structural rules across eighty countries instantly. A single wrong digit in a cross-border payment means days of waiting for a bounce-back. This MCP Server gives your AI client the ability to parse the country registry and verify the format. When you ask Claude to check a billing file, it calls the tool to scan the list. It flags format errors, wrong lengths, and bad checksums before you upload the file to your banking portal.

Clean financial data directly in your chat

The `validate_iban` tool processes messy financial files to clean up your record systems. Working with messy spreadsheets or CSVs from vendors is a headache. You can feed the raw text to Claude Desktop, and the model will clean the data. This means you get clean, verified records without writing python scripts. The tool handles over eighty country formats, so you don't have to keep track of regional rules yourself.
