Currency Minor Unit Lint

A local MCP server that scans code for money amounts sent to payment APIs in the wrong minor unit, such as a 100x overcharge in JPY.

What you can do

Checks money values in code against the minor-unit conventions of currencies, flagging amounts that would be sent to a payment API in the wrong unit. Surfaces cases such as a x100 conversion that would charge 100 times the intended amount in a zero-decimal currency like JPY. Runs as a local command-line tool started by the assistant. The supplied README does not document its tools or usage.

When to use it

Useful when reviewing or maintaining code that formats amounts for payment APIs, especially across currencies with different decimal places, and you want an automated check for unit mistakes before they reach production.

Requirements

Runs locally as a Node.js process via npx from the npm package; no authentication, environment variables or headers are declared.
