Feed your raw address strings to the `format_postal_code` tool. It runs strict regex checks to ensure your US, UK, BR, or CA records meet official standards before they hit your database. This keeps your records clean without relying on expensive, slow external APIs. Your AI client handles the validation locally, saving you time on every single record.

Offline postal validation

The `format_postal_code` tool operates entirely offline as part of your local MCP setup. It performs validation in milliseconds without sending your customer data to a third-party server. Your data stays on your machine, keeping your workflow private and secure. It is the fastest way to ensure address accuracy while maintaining complete control over your environment.
